Lol... People have asked me what the proof loads are like that we fire in every gun that we build. They are extra spicy. SAAMI has guidelines for the exact percentage over maximum that proof rounds are loaded to and there is no doubt when you fire them. We use a recoil absorbing fixture to clamp the barrelled actions into during firing for safety purposes. Here are a few pics of 7 PRC proof rounds that I have fired recently. I find it funny that the warning label says to not reload the casings. The case head flows into the ejector and extractor holes in the bolt face and gets sheared off when the bolt is opened and the case head swells above the rim where it is unsupported by the barrel. The primer pockets almost invariably open up to the point that the primer falls out. I frequently have to use a dead blow hammer to open the bolts on many rifles after proofing.
