.30 carbine crimp question

[Larry Gibson]

thanks for the responses, guys

highpowershooter: i'll definitely go with the crimp used on the right casing, then. thanks for the advice!

Litt'le Lee: i most certainly still use lube when sizing the cases. i use the dillon spray lube, lube up a bunch of cases, and every second or third casing put into the dies is a lubed case.

You really need to quit crimping the case mouths. The >30 Carbine headspaces on the case mouth and absolutely no crimp is required. If you do anything simple taper crimp to straighten and remove the case mouth flare. You are asking for some serious misfires in eithe and M1 Carbine or a Ruger BH.

Also the bulge below the base of the bullet is caused because the case is sized too much. It is called the "coke bottle effect". If you don't want it then simple back out the FL carbide die a little at a time until it goes away.
