I was just speaking in general terms which could be applied to all centerfire firearms. New Axis chambered in 30-06 with fixed pin protrusion. Bolt was disassembled and cleaned before the rifle was fired. Ammo was Remington Core Lokt. First box of 150's shot 20/20. Opened up a box of 180's and 2/10 that I chambered didn't fire. The pin strikes looked similar to the other fired rounds, and were not visibly different than other fired rounds. I tried to fire each of the two rounds 3 times each which resulted in very deep strikes left on the primer, yet would not fire.
