Superhornet--CCI does make one primer that is deliberately hard, their #34. It is intended for "7.62 mm NATO, 30-06, and 7.62x39 Ammunition." (Quote from my box of #34's.) Standard Large Rifle in size.

The idea is that some military autoloading firearms, notoriously the SKS, do not have a firing pin return spring, and with just a little gunk in the channel with the firing pin, can be prone to slam-fires.

(I understand the same is true of the Garand, but no experience there.)

With a harder primer, the chance of a slam-fire due to gunked-up firing pin is much less.

The #34 primer still functions perfectly well as a primer when hit enthusiastically by a firing pin propelled by the gun's hammer, just as it should.
