If you're loading at 8000psi or less any of the mild primers will work without a lot to worry about. I'm looking at 16grs of 700X in a Rem hull and 3/4oz of shot and with a Rem, Win, or Cheddite primer and they all have 9300 to 9900psi. If you go down to the 14gr loads they show pressure in the 7000psi+ range.
