I have a Stag super varmiter that I'm trying to load for. I'm new to the AR world. I'm loading some 65 gr SGK and not sure if a crimp is the way to go. Do you crimp some and not others? Do you crimp only one that have a cannular? I load for acc. so no crimp, or crimp for the set back. I've read both side or the fence and would like some detailed info.
