I have ordered a custom set of loading dies for my new 500 Jeffery and I was wondering if the resizing die expander ball was slightly undersized to allow a stronger grip on the bullet, would it eleminate the need for crimping? It is hard to find a stab crimper for a Jeffery.

I doubt that one can get enough neck tension to hold a 500 Jeffery.....that's some serious recoil and if it's in a double rifle it's risking pulling the bullets out of the case in a few shots. I'd think crimping is the norm always in these cases.

If the use is in a bolt rifle the case in the magazine might have the bullet shoved very deep into the case and provide a "nonnormal" shot.

does anyone make a universal stab crimper for big bores?
