Baikal MP-310 Range Report

Today I went with a friend to Lehigh Valley Sporting Clays and shot a round of 100. By halfway through the gun was opening up quite a bit more easily.

The gun had no misfires with  Federal and Winchester 12 gauge No.8 target loads. I did have some sticky extraction in the bottom barrel but only with the Winchesters. Both my friend and I have had problems with this ammo in the past, he in a Browning O/U, so as far as I'm concerned this is an ammo issue, not a gun issue.

I'm very happy with the Baikal MP-310. Only time will tell how durable it is, but for the occasional clays or trap shooter or hunter, it looks to be a good value. The one thing I plan to change now is get a set of extended IC choke tubes for it from Carlson's.

Baikal MP310 Ejector Tuning

After playing some more today with the Baikal MP310 over/under shotgun that I bought yesterday, I decided to tune the ejectors. Specifically, the ejector springs that are installed by the factory are much stronger than required. Here’s a good video describing how to remove the ejectors and clip the springs to reduce their strength.

Rather than a Dremel with a cutoff wheel, I just used dykes to clip 6 coils off each ejector spring, then deburred the ends with my benchtop belt sander.

Aside from clipping the springs to reduce the effort needed to close the gun, I also polished the bearing points on the ejectors and the slots in which they ride, and deburr all edges. I also polished the part of the barrel monobloc that bears on the pivot pin. Be careful when disassembling and handling the parts. I cut one of my fingers on a really sharp burr.

To smooth things up I used 600 grit wet/dry sandpaper, and gunsmith’s Arkansas stones from a set that I purchased last year from Brownell’s.

With these bearing surfaces polished up and the springs reduced, the action opens and closes much more easily.

I’m hoping to try a round of sporting clays next weekend with the Baikal.

Baikal MP310 Shotgun

I took today off and went up to Cabela’s to do some gun trading. I got decent prices on a couple guns, but their offer of $200 for a 1944 Underwood M-1 Carbine was ridiculously low. I therefore traded in my Stoeger Uplander 20 gauge SxS shotgun and Springfield M1911 that I haven’t shot much in years, and came home with a Baikal MP310 over/under 12 gauge shotgun.

I’ve been looking at the Baikals for awhile, since unlike most of the sub-$1000 over/unders, the Baikal has a reputation for being reliable. My guess is that they are the most common sporting guns in Russia. For example, I watched Happy People: A Year in the Taiga (which I highly recommend, BTW) yesterday, and in one scene there is a group of Russians and most if not all have some kind of Baikal over/under.

Since my expected use is a few rounds of sporting clays each year, along with some bird and small game hunting, it should serve me well. If I was going to be running thousands of rounds through the gun like serious clays or trap shooters, I’d drop the coin on a Berretta or Browning.

The Baikal is imported by European American Armory/US Sporting Guns and is made by Izhmash in Russia. They were also imported for a few years by Remington in their Spartan lineup.

The right side of the butt on this specimen has some nice looking grain.

As you can see, it’s also fitted with sling swivels unlike most Western guns. They are for a 3/4” wide carry strap.

The MP310 has a single-selective, mechanically resetting trigger, selectable ejectors/extractors, automatic safety, and comes with three choke tubes for improved cylinder, modified, and full. Compared with most other modern made shotguns that I’ve handled the length of pull is a bit short, which for me is good. At 5’6”, most modern sporting guns have stocks that are a bit too long for me. The Russian guns with shorter stocks fit me better.

As with a lot of other Russian made firearms that I’ve seen, fit and finish is a bit crude. This shotgun is sold as a hunting gun at a moderate price, so it’ll be no big deal if it gets scratched.

The one thing that may need some work is loosening up the action. It’s very tight to open or close. I did remove the butt stock and hose out the action with PB Blaster, then relube with some FP-10, which helped a bit. I’m hoping that a round or two of sporting clays will loosen it up. If not, I found some info on tuning the action.

I’m not sure when I’ll get a chance to shoot the Baikal, but I’ll post a report afterwards.

The First 3D Printed METAL Gun

The smart guys at Solid Concepts have created the first 3D printed metal gun, a 1911 in fact. Here’s a video of it being test fired.

World’s first 3D printed metal gun

Yes, it had a few functioning issues. However, as a proof of concept they’ve done a fantastic job. Now it just needs a bit of debugging.

The technology enabling this is not yet affordable for the masses. Remember when personal computers first came out? Your smartphone has vastly more power at a faction of the cost. Or remember when the first Apple LaserWriter came out and cost around $4,000? You can now get a better laser printer delivered to your door from Amazon for around a hundred bucks. Even if 3D printers capable of doing laser sintering for additive manufacturing don’t drop to similar levels, they’ll come down in price to the point where you can go in together on one with a few buddies without breaking your bank accounts.

Combine affordable 3D metal printers with easily downloadable CNC drawings or even the G-code needed to run the printers, and the statist dream of unilateral civilian disarmament fails utterly.

Hey Feinstein, Schumer, Obama, Bloomberg, Cuomo? You can’t stop the signal!

A Small Lathe Built in a Japanese Prison Camp

I’ve been doing some preliminary research into silencer designs prior to filing my first Form 1, and ran across this article about a small lathe made by a British POW being held in a WW2 Japanese prison camp. Link to ~1.1 meg PDF.

This lathe was quite a bit smaller than the modern Chinese lathes made by Sieg and Real Bull, and which are commonly derided as toys. Yet, the author of the article made good use of it, fabricating parts for artificial limbs, among other things.

There’s something to be said for picking up and learning how to use a lathe as part of your preps. It could come in useful in the event of an economic depression when manufactured items become hard to get and it’s a tool with which to earn some extra cash.

Sources for the modern mini lathes include Harbor Freight, Grizzly, Little Machine Shop, and Big Dog Metal Works. Also check out mini-lathe.com for more info.

Reviving an H&R Model 1900 Shotgun, Part 2

Both the metal and wood of the H&R Model 1900 that I bought last weekend were pretty grungy. The metal had a mix of grease, dirt, patina, and rust. The forearm wood had been cleaned but the buttstock was nasty, with a couple splits in the wrist.

I started cleaning up the metal first. I used Kroil, steel wool, and paper towels to clean off the active rust while leaving most of the patina. Here’s the action, showing the patent date stamps above the pivot pin, which had been completely obscured.

(If you right-click on the photos you can then view them full size in another tab.)

The top of the barrel at the breech:

The choke is probably a full choke.

The wood was filthy. I took this pic to show the contrast between uncleaned wood (the wrist) and cleaned wood (the butt).

To clean the wood I used steel wool wet with lacquer thinner, and periodically wiped off the resulting slurry with paper towels. Except for the cracked wrist it’s perfectly sound. I flushed the cracks out with lacquer thinner then let the stock dry in the sun. I then flooded the cracks with superglue.

The only way to know if the glue is enough to prevent further cracking is to shoot it. If not, I’ll wrap it with wire like you see on a lot of old guns.

After the superglue dried I gave the stock three coats of dark walnut tint Watco Danish Oil. It came out pretty nice, IMO.

After cleaning up the barrel I hit it with some Birchwood Casey cold blueing solution. I applied several coats and let it sit for a couple hours. The white scratches that were on the barrel are now gone, and it has an overall brownish patina.

The cleaned and refinished gun looks good now. It doesn’t look new. It looks like a well used, old gun, rather than a neglected, filthy old gun. It should have some life it in yet.

Reviving an H&R Model 1900 Shotgun, Part 1

Last weekend I bought this H&R Model 1900 shotgun from the neighbor of a friend. I paid $60, which considering the gun’s condition, was probably too much. However, the neighbor is a widow selling off some of her late husband’s guns, so I don’t really care in this instance.

It’s a single shot 12 gauge. After getting it home I identified it as a Model 1900, which places the date of manufacture between 1901 and 1915. It was probably made with a 2.5” chamber but I measured it at 2.75”, so it’s likely that it was lengthened by a gunsmith. This was a fairly common operation after 2.75” shells became popular.

The Model 1900 was made with either an extractor or an ejector, and a twist steel or plain steel barrel. This one has a plain steel barrel and extractor. If it had a twist steel barrel I’d relegate it wallhanger status, but this one is mechanically sound so I feel comfortable shooting it with low brass loads or Aguila mini-shells.

In my online research I found this scan of an old catalog:

When this shotgun it came into my possession it was covered in about a century’s worth of rust, dirt, and dried up grease. Also, the barrel looked like someone had taken a Scotchbrite pad to it in an effort to clean it up, but never got around to finishing it. However, it is mechanically sound and locks up tightly.

Unlike other top break single shots I’ve seen, the way you take it down into two pieces is by removing the barrel pivot pin.

Open the action, lift the toggle, rotate it 90 degrees, and then you can pull it out. Now, you can separate the barrel and forearm from the frame.

I put a few shots through it last weekend and the choked barrel throws a pretty decent pattern at 15 yards, centered on your point of aim.

The gun cleaned up OK, which I’ll detail in Part 2.

Remember 9/11, Twelve Years On

On 9/11/01 I walked into the break room in our Plymouth Meeting, PA office a few minutes after the first plane hit the WTC, stopped dead in my tracks upon seeing the TV, and said aloud, "Holy shit!" A coworker repeated this about 30 seconds later.

We didn't know it was an attack yet and so I left for a job down in Philly, where I was to me one of our VPs who wanted to see a customer installation in person. We got down there and I completed most of the job before we decided it was time to leave, and I told the customer I'd come back to finish the job. Once I heard about the second plane hitting, I knew it was no accident, that this was an act of war. I recall CNN's website crashing under the load as seemingly everyone hit it in an attempt to find out what was going on.

It took awhile to get home because traffic was bad. My wife made it home OK after her students were dismissed. I spent much of the afternoon trying to find out the status of family in Manhattan, on Long Island, and down in Arlington. I later learned that one of my cousins was working downtown near the WTC and had to run for her life. Thankfully, she made it.

One thing that impressed me was how the Internet functioned as designed that day. When a large central router was taken out in the collapse of the WTC, the Internet routed around the damage and I was able to reach a cousin on Long Island using AOL Instant Messenger. Phone calls to the NYC area were basically impossible.

In the wake of 9/11 the country came together like I had never experienced, but unfortunately was soon torn apart over what turned out to be misguided foreign adventurism with the goal of nation building in a backwards shithole that we should never had invaded. Worse, IMHO, is how members of both political parties took advantage of the country's mood to ram through anti-freedom legislation like the Patriot Act, the creation of the TSA, and engage the USA in a never-ending War On A Tactic.

Having ruined the Republican brand with foreign interventionism, the American public proceeded to elect Not-Bush, thereby removing Carter from the position of Worst POTUS Ever. His signature accomplishment will give the Federal goverment control over about 20% of the US economy despite massive and increasing public opposition.

The Attorney General of the US -- the nation's highest law enforcement official -- has repeatedly refused to investigate slam-dunk cases of voter fraud. Worse, to undermine the Second Amendment to the Constitution -- which he swore to uphold and defend -- he oversaw a gun running operation to Mexico causing the deaths of hundreds of Mexicans. If another country perpetrated something like Fast and Furious on the US we'd rightly consider it an act of war.

The IRS, never a public service agency, has been transformed into a tool of oppression by targeting political opponents. The exact effect this had on the 2012 presidential election cannot be quantified but was no doubt significant in stifling Tea Party voter turnout efforts.

Under the guise of "protecting us from terrorism," the US govermnent has created a surveillance state that would have Hitler, Stalin, and Mao doffing their hats in respect and awe.

One year ago one of our embassies was attacked and four Americans, including the ambassador, were murdered. The reaction of the the administration was to launch of cover-up, making anyone paying attention wonder just what they are covering up. Could it be gunrunning through Libya to Syrian rebels?

A dozen years on we've gone from having a POTUS who at least knew the enemy was, to a POTUS who now wants to turn the US military into Al Qaeda's air force. In the face of overwhelming opposition he delivered a disjointed speech last putting on display for all but his most devoted worshippers how incompetent, indecisive, and amateurish he is.

Twelve years after 9/11/01, I feel like I stepped through a portal into Bizzaro World. Does anyone know the way home?

Trapping Feral Pigs and Other Parables of Modern Life - Matt Bracken

This article is worth reading in full:

Trapping Feral Pigs and Other Parables of Modern Life
by Matt Bracken

Professional trappers don't catch fast-breeding and destructive feral pigs using hunting dogs and guns, or in little traps one or two at a time. The wily pigs quickly learn to evade humans after such fleeting contacts. So how do the pros trap entire feral pig herds, eliminating them all, from granddads to piglets, in one go? They feed them, most generously. They kill them with kindness.

First, in a clearing in the woods, the trappers build an enclosure about twenty feet on a side and four feet high, made of stout wire mesh. There is an opening on each of the four sides of the pen. The pen is loaded with corn and other pig favorites. At first, the suspicious hog honchos will send in a few of the little ones as scouts. The scouts come and go at will, eating to their piggy satisfaction, until eventually suspicions die and they are joined by every other member of the herd right up the chain of command. The pigs soon come to believe that if nothing bad has happened to them after entering the strange wire enclosure full of corn, then nothing bad will ever happen. Their "normalcy bias" kicks in very quickly.

Soon, the pigs can't imagine any other life. Rooting for tubers? An unpleasant task of the forgotten past. Nightly the herd eagerly trots to the free corn in the pen, and they fail to notice when one of the openings has been closed off with another panel of wire fencing during the day. Pigs are said to be as smart as dogs, but neither can count to four. Nor are the closings of the second or third openings much noticed. Finally, all that remains for the trapper to do is to install a powerful spring-driven trap door above the last opening. The entire tribe of formerly wary feral hogs once again enters the pen, and with a metallic clang their miraculous corn nirvana turns into a death trap.

The moral of the story: If it looks too good to be true, it probably is. Don't go inside the "free corn" pen, not even when all the doors are open. Free food is as dangerous as the sirens' song to ancient mariners. It is all too easy to get used to being fed, and then to miss the exits closing one at a time.

2. The Turkeys and Farmer Brown

Pigs are Einsteins compared to turkeys. Turkeys are so stupid that care must be taken to prevent them from killing themselves by accident. For example, if incorrectly stimulated, they might stampede into a corner of a feeding lot and trample many of their brethren to death in their urgency to follow the herd.

If turkeys think at all, they think of Farmer Brown as "the food man" or "the food god." So you can imagine their simple and unreserved joy at seeing the food man arriving to dispense the daily manna. For 364 straight days they believe they are living in turkey heaven, and they worship the food man, until on day 365 he unexpectedly takes an ax to their necks. (Hat tip to Nassim Nicholas Taleb and his seminal book, "The Black Swan" If you have not yet read it, you are way behind the learning curve. It's waiting for you at your local library.)

The moral of the story: If somebody is feeding you every day and asking for nothing in return, give an occasional thought to his motives and his possible end plans. Not everybody that feeds you loves you. The normalcy bias can kill you.

3. The Buffalo Jump

Native American Indians hunted on foot before the arrival of Spanish horses in North America. Bows and arrows and spears were not showstoppers against stampeding herds of bison, each weighing up to a ton. The Indians understood bison much better than the bison understood the Indians, however, and so the bison repeatedly failed to discern that all the pesky humans waving flags and setting grass fires were funneling them into a narrow draw and then to a yawning cliff, with squaws and children waiting below to commence the butchery.

The moral of the story: If you are being stampeded and funneled, it might be toward disaster, not away from it. Take any exit and go another direction. Read about the then-Greek city of Smyrna in 1922 to see a human Buffalo Jump in action. Wiki link to the "Catstrophe of Smyrna"

4. The Lemmings

The lemmings we are interested in are the small furry rodents that live on islands around Norway. For most of history, their mass charges into the frigid waters were seen as some kind of group suicide. Today, they’re understood to be the result of the little rodent's rapid gestation period kicking into high gear during rare periods of abundance of seed grasses sprouting madly during particularly mild arctic summers. In a matter of months the lemming population explodes, but eventually every last seed is eaten, and not another seed will appear until after the passage of the long arctic winter. The starving rodents packing the small islands can either die in place or undertake a desperate swim to greener pastures on other islands beckoning in the distance.

The moral of the story: There doesn't need to be a pig trapper or a turkey farmer in the equation to cause a mass die-off event; nature can do it all on her own. And nature doesn't care about your schedule, or your personal problems.

5. The Land Crab Massacre

One day in Puerto Rico a platoon of Navy SEALs had to drive in a few trucks and vans to an isolated rifle range way out in some swampy corner of the Roosevelt Roads Naval Base, now sadly closed. A few miles of gravel road paralleled the Caribbean shore, with mangrove trees close on both sides of the narrow track. You had to access this rifle range at certain times during the daily tidal cycle, or the road might be under water. The frogmen spent the day shooting guns and blowing things up, then at sunset packed up the trucks for the quick run back to their beloved NavSpecWar Det Caribbean.

Truck headlights illuminated a moving sheet of land crabs, migrating from the ocean toward the land for the night. Land crabs have a body about the size of a fist, and one claw as big as a Maine lobster's. They were so tightly packed that you could not toss a hat into their midst without hitting two or three: a near solid mass of them covering a mile of gravel road and the mangrove swamps on both sides. All the SEALs could do was drive over them in their government trucks, pulverizing thousands of them, maybe millions, leaving two wide swaths of crushed crab, crackling and squishing beneath our tires for a mile.

On the return trip to the range the next day, not a sign remained of the land crab holocaust. The smashed crustaceans had been immediately devoured by their erstwhile kin, who were probably happy that the hard work of shell-cracking had already been done by Goodyear tires. A mile-long crab massacre was followed by a cannibal feast that left no trace, overnight.

The moral of the story: Don't be caught in the middle of a mass migration where you have no room to maneuver independently. Any outside force, or your neighbors, can smite you at will. Like Desert Storm's "Highway of Death," refugee columns attract warbird attention the way that honey attracts flies. History is full of refugee columns being strafed, on purpose or through mis-identification. Or like the bison, refugee columns can be herded into traps, and the individual refugee can do nothing to prevent it. This is a paradoxical case where the normally presumed “safety in numbers” is a deadly betrayer instead of a savior. Given a choice, going it alone beats The Buffalo Jump every time, but it’s very hard to bolt from the herd.

Raspberry Pi Light Sensor

Today I brought my Raspberry Pi into the office and got the GPIO connectors working, then followed this tutorial to setup a basic light sensor using a photocell.




One of my goals is to come up with an RPi-based system that measures, logs, and reports temperature. Once I get it prototyped I want to setup several of these systems in our 3100 square foot data center so we have a better idea of how each part of the room is being cooled.

Shooting My Chinese Horsebow Again

For the first time all year I flung some arrows downrange with the 50# Chinese horsebow that I bought in 2012 from eBay seller "handmadebow." I remain impressed with the bow, which shoots as well as my much more expensive 40# Toth Magyar horsebow from Seven Meadows Archery. (The Toth bow is better finished, to be sure.)

Much of my shooting today was with some Easton carbon arrows that I bought last year on closeout from 3Rivers Archery. The carbons are a lot lighter than my cedar arrows, and of course much straighter and more consistent. They fly much faster from the horsebow, flat as a laser out to 12 yards. The speed comes at a price in the form of greatly increased hand shock. The lightweight carbons are much less pleasant to shoot than wood arrows, and I enjoyed shooting the bow more after I switched to my cedars. They fly noticeably slower but the bow is quieter with less hand shock, and they still hit with an impressive thump.

Even though I had not shot the bow since last Fall I was able to keep most of my shots in a group the size of a paper plate at about 12 yards. I plan to practice more with it and hopefully take it hunting this year.

Pietta 1873 Millenium Single Action Revolver

Yesterday at Cabela's I bought a Pietta 1873 Millenium replica of the Colt Single Action Army revolver. The gun is chambered for .45 Colt, has a 4-3/4" barrel, and a matte blued finish with a brass grip frame and wood grips. Cabela's also sells them in .357 Magnum and .44 Magnum, with the same matte blued or a nickel finish.



Overall the Pietta is a pretty faithful copy of the Colt SAA, with the obvious exception of the utilitarian finish. The other way in which is diverges from the SAA's design is the presence of a safety that works by pushing the cylinder base pin back towards the hammer, to prevent it from dropping all the way and striking a primer. IMO it is neither easy to operate nor very robust, so I intend to treat the gun as a traditional single action, and keep an empty chamber under the hammer if I carry it.

Out of the box the action was very smooth and the trigger was very crisp, with absolutely no creep or takeup. It's a couple pounds heavier than I'd like, however, so I will do some careful stoning to lighten it a tad.

I already had a few boxes of Black Hills .45 Colt cowboy loads at home. They feature a 250 grain hard cast RNFP bullet at about 750 FPS. I wanted to pick up another box or two of ammo but the only .45 Colt that the store had in stock was Buffalo Bore +P, which shouldn't be used in SAAs or clones. However, they did have one box remaining of Ultramax .45 S&W Schofield with a 180 grain bullet at 650 FPS, a real mouse fart load. (For those unfamiliar with .45 Schofield, it shares the same case dimensions as .45 Colt, but is shorter. It can be safely fired in the Colt chamber.)

Today I brought the Pietta to my gun club and fired it at 25 yards, then 10 yards. At 25 yards it shot about 8" low and 8" left with the Black Hills .45 Colt loads. At 10 yards it was about 6" low and 6" left. The Schofield rounds impacted closer to center, but still low. This 10 yard group of 12 shots was fired before I started filing the front sight to raise the point of impact. I was aiming at 6 o'clock on the bullseye.



The two flyers were my fault.

The gun digested 100 rounds today, mostly trouble free. I did have a problem after the first three shots, because after playing with the safety last night I apparently failed to properly seat the cylinder base pin catch in the correct detent, and the pin started walking out. This prevented the cylinder from rotating so I had to dismount it from the gun. This goes in the operator error column.

The other issue I had was ammo related. One empty .45 Colt cartridge case was very tight in the chamber after I fired it, and I couldn't eject it until I again dismounted the cylinder and smacked the empty out with a mallet, using the base pin as a drift. Most of the remaining empties actually fell out if I elevated the muzzle, even without using the ejector rod. So, that one gets chalked up to an ammo problem.

If you want a Colt Single Action Army replica that won't break the bank, the Pietta 1873 is worth a look. As a copy of the SAA, it is not suitable for heavy loads, but the original ballistics for the .45 Colt round are nothing to sneeze at. A 250 grain .45 caliber bullet going about 900 FPS will take game up to deer size cleanly, or prove effective for self defense.

Crosman 2300T Improved Front Sight

Over the weekend I used my new lathe and my mill to make a nicer front sight for my Crosman 2300T. Details here.

Crosman 2300T Air Pistol

Back in January and February I posted a few times about using airguns for cheap, quiet indoor marksmanship practice. While I have a couple of suitable air rifles, I was lacking a good air pistol. My old Benjamin has mediocre sights and pumping it up 2 or 3 times between each shot gets old quickly. The Crosman 38T revolver that I bought back in the 80s and that I had hoped to use will no longer hold gas, and nor will the late 90s vintage RWS C225.

So, when I got a $100 Amazon gift card for Father's Day, I decided to put it towards a Crosman 2300T CO2 powered air pistol. I ordered it Monday morning and with Amazon Prime, it arrived on Tuesday, even though I did not pay extra for overnight shipping. This is a photo from Crosman's website:



The .177 (4.5mm) caliber 2300T is one of a series of CO2 powered pistols from Crosman. The .22 (5.6mm) caliber 2240 is on the low end, with the 2300S at the top. You can also order custom variants from Crosman's custom shop. The key features of the 2300T are:

  • .177 caliber
  • Single shot bolt action
  • 10.1" barrel
  • Single stage adjustable trigger, with overtravel stop
  • Adjustable rear sight and blade front sight
  • Steel breach, grooved for optics (as opposed to the plastic breach of the 2240)
  • Crossbolt safety mounted behind the trigger.
  • Weight of 42.5 oz.
  • MV up to 520 FPS
  • 40 shots or so per CO2 cylinder
The first order of business upon unpacking the pistol and verifying that it wasn't loaded, was to install the rear sight. To do so I had to turn in the large screw on the rear top of the breach, to provide more clearance for the rear sight, then slide the sight into a dovetail and tighten two set screws with a provided Allen wrench.

I then noticed that the front sight was canted a bit to the right. Using a pair of slipjoint pliers with a couple layers or duct tape padding the jaws, I was able to straighten it.

Before shooting any pellets I dry fired the gun and determined the trigger pull was adjusted too high. Following the instruction pamphlet, I removed one of the grip panels and turned the brass trigger adjustment dial to lower the pull. It's down to a couple pounds now with minimal takeup but a fair amount of creep. I haven't tinkered with the overtravel adjustment yet.

The ambidextrous plastic grips are comfortable for me, but I have fairly small hands. A shooter with large hands may want beefier grips.

The LPA rear sight is shaped a bit like the Novak rear sights found on many modern service pistols. There are white dots on either side of the notch. The front is a plastic blade on a barrel band. I'd rate the sight picture as acceptable for plinking but mediocre for target shooting. I plan to use a Sharpie marker to blacken the white dots. The rear sight notch is a little too wide, IMO. The front sight is too shiny, but since it's plastic you can't smoke it with a match or candle.

The balance of the pistol is neutral. It could use a bit more weight towards the muzzle. I am considering making a replacement front sight/muzzle brake unit out of aluminum to improve the sight picture and add a little more weight towards the muzzle end.

I put 10 rounds through the pistol Tuesday night, plus another 40 or so tonigh. The target below was shot from 25', one handed, with RWS Meisterkuglen pellets. Power was from an old Daisy CO2 cylinder. I put a drop of some Air Rifle Headquarters silicone spring cylinder oil on the tip of the CO2 cylinder before I put it in the gun; Crosman recommends using a drop of their Pellgun Oil. I received a tube of that today.


Point of aim was at 6 o'clock on the orange bull.

One oddity was that on shot number 6 the valve stuck open and gas started to leak. I recocked and snapped the gun, which stopped it. I regard this as a fluke and probably due to a burr.

Despite the canted front sight and the stuck valve, my initial impression is favorable. As long as no more mechanical issues arise, it should make a good pistol for indoor marksmanship practice. It's nice to shoot and accurate.

The Crosman 22xx series is sort of the Ruger 10/22 or AR15 of the air pistol world, in that they are modular, easily customizable, and there is a large variety of aftermarket and Crosman-branded parts for modifying the gun to your own preference. For example, Crosman sells a shoulder stock to convert it to a carbine. Longer barrels are available, including in .22 caliber, and even valves which enable more CO2 per shot for higher velocity.

Shooting a CO2 powered air gun isn't as cheap per shot as a spring piston or pneumatic gun, but at most it's on par with a .22 rimfire.

Overall, the Crosman 2300T is a good choice for target practice, but it can be made better with some modifications.

Machine Shop Update

On Saturday I completed the installation of digital read outs (DROs) on my Grizzly G8689 mini mill. Previously, I'd installed a belt drive conversion from Little Machine Shop. The DROs will enable me to make much more precise cuts, while the belt drive conversion made the mill a lot quieter, smoother running, and increased the top RPM to 4300 should I ever need it. Both are worthwhile mods, IMO.

However, a lathe is still the basic machine tool to have in a machine shop. After much additional online research today I ordered a Big Dog 7x14 benchtop lathe. Unlike most of the benchtop hobby lathes on the US market, this one is made by Yangzhou Real Bull, rather than Sieg. Included feature and accessories are a digital RPM display, lever lock tail stock, a steady rest, a follow rest, tail stock chuck and a live center, 4" four-jaw chuck, and metal transmission gears. I still have the lathe tool kit that I ordered when I placed my original order with Grizzly, so I should be able to get up and running with it immediately.

Delivery should take 5 - 10 days, after which I'll post a review.

Home Machining Website

I decided that the format of a blog isn't ideal for documenting the work I'm doing in my home machine shop. So, I created a site using Google Sites, Dave Markowitz's Machine Shop. I will be documenting various projects there. So far, these include doing a belt drive conversion on my Grizzly Mini Mill, and adding digital readouts, which is currently a work in progress.

I hope you'll check it out.
