LRRPF, I am trying to remember (getting old sucks). I know that the Grendel max chamber pressure is limited by the AR15 bolt design, but I thought that you seldom see "pressure signs" at 52,000 psi. In other words, is it generally a bad idea to load until you see flattened primers rather than sticking to book loads?
Thanks.
Thanks.
