Long story - short version. I bought a new rifle and worked up some loads and went to the range. The gun didn't go boom! Thought it might be me - turned out to be an overbored chamber. The rifle has been fixed by factory but I have 23 rounds that have a dented primer that didn't go off and won't fire in the gun. I've pulled the bullets and powder. I'd like to save the brass but .... How can I deactivate the priming compound? Am I playing with fire and just consider the loss as furthering my education?
