Hey Otis,

Looks like your bore is on the tight side of standard which is good. You will need cast bullets sized .380 for best accuracy. I have found that the Western cases at 2.082 work best in several of my guns so I use that length in all of my 38-55's.

A very light crimp in the crimp groove is best. Some shooters try to move the bullet out to just touch the rifling. Don't waste your time, the 38-55 is not a varmint gun, COAL is of little meaning so long as the round feeds correctly. The 38-55 has a long tapered throat, I try to avoid that throat and it's issues thus the intermediate length brass (2.082).

You may know all this already but some of our readers may not. I wont bore you with any more on this.

Thanks
JB

Oh yes, for anyone who thinks that the 38-55 will not shoot, here is a couple of 100 yard targets shot with laser cast bullets over 10 gr. of Unique. Five shot groups.

Witnessed by several other shooters at the range.
