Friend of mine has a brand new 12 VLP in .223. Shooting two different types of ammo - cheap PMC and Hornady 75gr BTHP Match - he's getting all kinds of pressure signs. Almost all of the rounds have the primers cratered, a few were pierced, and one was a complete blow out. I shot some of the same PMC ammo in my AR and it showed no pressure signs. The barrel was thoroughly cleaned prior to shooting and he was cleaning after every few shots to help with barrel break-in. He's going to call Savage today, but I thought I'd post it on here and see what the group thinks...
