This is in a gas gun, Monster 20" bbl. Jam for Nosler 105 rdf for this barrel is at 2.340"
The primers didn't flatten a whole lot, but did crater a medium amount.
I've had primer piercing in my bolt 6ppc 1-7 twist rap with RL15 and CCI 400's at modest load levels with the 105 class projectiles.
I would much prefer to use a stouter primer, but only have a hundred or so of CCI 450's right now.
My suspicion is that the 400's will only hold up to medium pressure loads in the 6 ARC or similar cartridges although they work pretty good in .223.
I'll check out the link CZ guy posted and see what insights can be found.
