Just another bit here, the primer isn't backing out at all and everything else looks fine on that cartridge case. I kind of like the Remington/Savage/Ruger/Winchester added safety feature. It's a lot better than picking brass fragments out of your shooting glasses if something goes wrong. Like it or not, When you're mass producing anything, "If something can go wrong, it's not a matter of IF but when". The smiths on this board are right, it is a design feature and a good one. Those craters aren't sharp and there's no piercing evident as there would be with excessive pressures. I don't think there is a North American manufacturer that doesn't have the same feature.
