Are you guys crimping bottlenecks for magazine fed bolt action? (taper or Lee FCD)
The "universal wisdom" - which is far less universal than it used to be - was that crimps are for semiautos, not for bolts. But where did that come from in the first place? Is there a difference in the recoil or is it simply because of rounds getting smacked into the front of a magazine? (or more accurately, the front of the mag smacking into the rounds)
I've been reading about potential problems from crimping and a lot of people don't do it anymore, even for semiautos.
I guess tl:dr:
1. Is the reason for suggesting crimp for semiautos because of something different about the recoil or just because of the magazine?
2. If it's just the magazine, then does the same advice apply to magazine fed bolts?
3. Are you crimping your bottlenecks? In which applications?
