I have shot stout loads out of the Black Diamond XR (150 grains of loose powder) and the primers stayed in tact.
And I would say they do because the breech plug allows the pressure to vent off enough before pushing the primer or the entire assembly out of the primer pocket... but we pay for that venting with amount of carbon found in the breech and bolt area....
