All large rifle primers are .027" cup thickness. Have not heard of any being of a harder or softer material, only larger or smaller in diameter.

Primer piercing or more accurately, blanking, is commonly caused by too large of a firing pin hole in the bolt face. This will also cause cratering, even before excessive pressures are reached. Oh, and those "blanks" are somewhere in the rifle. They will stack up inside the bolt and eventually cause failure to fire and some can get down into the trigger area also.

Rather than carrier weights, many of us in highpower fill the buffer with lead or lead shot. It will not help your problem, but it helps with brass longevity and felt recoil.
