Model 1901 .38 colt army rev.

[joem]

I aquired a revolver several years ago that was listed as a model 1896 army. I found a copy of a Department of Ordnance book that says it should be a model 1901. This book stated the bullet diameter should be .377 and 158 gr RNL. As of now I shoot 170 gr .361 diameter bullets. This is the first I've seen that diameter specified. I thought it was supposed to be .362. Has anyone more knowledge on this subject?

Why not slug it?

I guess I could slug it. I took a .357 diameter and drove it through the bore. It was not loose but it went through pretty easy. With the .361 bullets accuracy is much better but I didn't try to drive one down the bore. Again my question was more about the .377 diameter bullets. That book was published in 1905.

I've misread the old print of this cartridge. The .3775 is the dims over the OD of the case. Sorry.

Those 38 long colts were also heel based bullets, not at all like current 357/358.

I know it. I did buy some .361 cast 170 gr but they are not made anymore. I've ordered some S&W .38 bullets so I'll see how they shoot. My supplier says 5 to 6 weeks for delivery.
