Wheelgun Wednesday

Today I was able to sneak out to the range for a couple hours for Wheelgun Wednesday. I brought two hoglegs with me: A Cimarron Model P in .44-40 WCF and a Cimarron Pistolero in .357 Magnum, shooting .38 Special ammunition.

First I ran two new-to-me handloads through the Model P. Both were loaded in Starline brass with a CCI No.300 primer and 7.0 grains of Winchester 244 powder. The first batch was loaded with a 200 grain lead round nose flat point (LRNFP) bullet, while the second was loaded with a 215 grain LRNFP.

The results were interesting and the opposite of what you'd expect. I.e., the lighter bullets ran slower than the heavier bullets. I attribute this to higher pressure with the higher bullet. I've seen this before with .38/44 handloads, where 5.9 grains of Herco gave ~100 FPS more muzzle velocity with a 178 grain Keith bullet than a 158 grain LSWC.

With the 200 grain bullet I got an average muzzle velocity of 827.1 FPS for 304 ft.lbs. of energy from the Model P's 5.5" barrel.

The 215 grain bullets ran at an average 903.3 FPS for 389.7 ft.lbs. of energy. About a 76 FPS difference. Both strings were 10 shots.

After running the .44s over the Garmin I changed to 10 yards and ran the Hickock-North drill with both guns, and also 6 shots one-handed on a B-8 center, followed by 10 shots fired two-handed on a B-8 center.

The ammo I used in the Pistolero were handloads with a Lee TL358-158 SWC over 4.7 grains of Unique, which ran about 842 FPS from my 4" S&W Model 15 last week. They should be going around that from the .357-chambered but 4-5/8" barreled Pistolero.

Anyway, I need to continue to work on my one-hand shooting and well as file down the front sight on the Model P, which shoots low.
