Was it some fella named Pascal that came up with the idea that the same pressure that sends your bullet to the target is also trying to propel the primer rearward out of the primer pocket?

Garand's experimented with the rearward thrust of the primer operating a rifle.
He eventually went to gas operation.

Yep. Pressure can cause ALL primers, including Large Rifle primers, to exert a good amount of thrust/force rearward.
Watch your headspace, and primer pockets.
