first question) I’m trying to load .308 for my AR10, so I know I need at least some crimp. I have the Hornady custom grade dies, and I have 100 rounds seated with no issues. I tried to go back and crimp my seated rounds (because that’s what I’ve always done on my .223 RCBS) but I am very frustrated at this point. I have read the instructions and watched the Hornady video on YouTube 20 times now. On an unseated round, I am able to achieve roll crimp but on my seated rounds that I made with no crimp, going back and trying to crimp them only makes the shoulders bulge. At this point I am scared I’m going to have to disassemble 100 bullets and spend forever adjusting the die to seat and crimp in one stage. What am I doing wrong?! Using 125 grain FMJBT.
2nd question) Loading another batch with 150 grain FMJBT, I achieved good crimp in the cannelure but the Hornady says not to roll crimp if there’s no cannelure. However, my crimp in the cannelure puts my round WAY under the MIN OAL. I trimmed my case to the length the manual said but the powder im using says min oal is 2.800. Crimping in the cannelure puts my oal around 2.735. Can I disregard Hornadys YouTube channel and roll crimp under the cannelure to achieve good OAL or should I trash the bullets an start over?
