Got me a box of 400 grs Nosler Partitions in .416 Rigby...I noticed they have cannelure..am I "supposed to" crimp the neck into this cannelure? Will they move in the case under recoil if I don't?

Thanks

Frans

I crimp mine very lightly. Don't really know if I need to or not. I do it cause I can. Never had a problem not crimping them but I've not had one ride in the magazine long enough to find out if not crimping would create a problem. Don't cost nothing to do it and it might save a problem someday so I do it.

Frans : I do crimp mine the front wall of the mag. box on my BRNO has dents in it where the bullets hit it under recoil
