I'm new to reloading and the .38-55, but what I've found, having had similar problems, the Winchester and cut down .30.40 Krag brass do that. Starline doesn't so much. I put a Lee Factory Crimp Die on them and they are all fine. Your rifle, like mine is likely overbored and likes a fatter bullet. That's probably why the factory ammo didn't shoot well. I'd guess you buddy found that and it's why his hand loads are shooting. It sounds like Factory Crimping, not the roll crimp, may do the trick for you. It'll take the flare out of the case. Good luck, let me know how you do.
Hi Tom, Yeah, there's long and short .38-55 Brass, new and used and cut down from .30-40, but I have been able to make them all work.......with a lot of work, time and effort. Now, I think I've got it figured out and it's pretty simple.
I almost put Tim's .38-55 barrel to work this morning. A buck came out at 150 yards about 7:30 and was moving closer. I slowly raised the rifle......and he was gone. I don't know if he winded me or saw me move. He had a rack, but in the low light against the trees I couldn't tell what he was. I never even got the scope on him.
Thanksgiving has always been our lucky day. Perhaps this afternoon or tomorrow.
