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. Wanna kill these ads? We can help!
