What did I miss?
A pissin contest.....and some discipline applied to those that did wrong. :yield:
It appears that some of the 6.8 guys are not crimping, don't know if that's a risky thing or not. correct me if I'm wrong, but doesn't crimping increase the tension of the grip of the neck on the bullet, and therefore changes the case pressure build-up and bullet release characteristics? I don't generally notice crimp/non-crimp info on load tables.
I never crimped for the 308s in my Rock River LAR-8. I had the 16" mid-length, and never had an issue with setback.
Like it was somewhat mentioned before, you can take a dummy round with no powder or primer, and cycle it hard, repeatedly in the action. If you take before and after measurements of the OAL, you would be able to see if your tension is more than likely enough to keep the bullet in place.
