I do not, would not crimp a 300 Win Mag and see no logical reason to do so.........

Re: To crimp or not to crimp?

In a light rifle with lots of recoil and using a magazine, the loads not fired could have the potential of setting the bullets back. In a single shot I doubt that it would be needed unless your powder needs more pressure than the neck tension produces to be accurate.

edge.

Re: To crimp or not to crimp?

Does your bullets have a conalure on them? Probable not,therefore they are not intended to be crimped. You apparently have a set of Lee factory crimp dies.....a fishing lure in my opion.. Crimping is benificial in Big Bore revolvers inorder to eliminate the bullets from pulling out of the case and tying the gun up. Also big bore rifles,such as 458 Win Mag where recoil may force the bullet deeper in the case with the remaining bullets in the magazine. Also lever action tubular feed magazines benifit from crimping,but not a 300 Win mag.......

Re: To crimp or not to crimp?

yes some of the bullets i use dose have a canalur and some don't.
I know some people always crimp and some don't i was just asking for knowledge.

i haven't noticed if my gun is moving the bullet in the case or not.
