I don't reload .357 Sig, but I have reloaded thousands of a similar round, .400 Cor-Bon. Bullet setback should be a concern with any handgun bottleneck, due to the brevity of the neck. I solved the setback problem in .400 Cor-Bon (after blowing up a G21) by canneluring all bullets that I reload for .400 Cor-Bon and .40 Super, and roll-crimping into the cannelure.

I had trouble with RCBS sizing dies scratching my .400 Cor-Bon brass. Sent back three. They all did the same thing. Went to Lee, with no problems. Still use the RCBS seater/crimper die, with wonderful results.
