[QUOTE="westcliffe01, post: 771016, member: 35183"] Crimping is yet another source of variation and given that only 3-5 rounds fit in the typical hunting magazine, there is little concern of the bullet positions being moved by recoil forces in the magazine. The last bullet experiences N-1 recoils before it is loaded in the chamber (N being number of rounds in the mag). Why not do a simple test: Take your reload with the heaviest recoil and measure the OAL of each cartridge before you load it in the chamber. Then fire all but the last one. Take that one out and check its length again. If its length didn't change then all crimping will do is degrade your accuracy. So just live and let live. If he wants to crimp his, fine. He may be spoiling the drag coefficient if he leaves a mark on the surface of the bullet too. Do you think the Berger reloading manual has anything to say about crimping ? I think not. [/QUOTE]
