Smith & Wesson Model 640 Range Report.

I'm pleased to note that the gunsmithing I did on my S&W Model 640 I did this morning worked out. I took it to the range tonigh and put 50 rounds of my handloads through it. The loads were a 148 grain button nose, bevel base wadcutter from Matt's Bullets, 3.3 grains of Alliant Bullseye Powder, and CCI primers in Winchester wadcutter brass. The gun functioned perfectly.

Something to mention is that of the major American primer brands, CCIs have the hardest cups. So, if the gun runs well with them it should work fine with Federal (the softest), Remington, or Winchester primers.

Note that the reason I needed to work on it earlier today was because I'd installed an Apex Duty/Carry kit in it, which has a reduced power hammer spring and extended firing pin. (The kit also includes a reduced power rebound spring but I managed to launch that into the ether so my gun has the OEM rebound spring.) Even without the lighter rebound slide spring it's much easier to shoot well than as it came from the factory.

This is 50 shots at 7 yards. All of my shots were on the target.

This gun will definitely be carried.
