Running on the ragged edge, you are eventually going to have a problem, and you did. You are lucky all it was is a broken extractor. Load hot if you want to, it is your gear and face, but don't pooh pooh the warnings provided here by saying you got away with it for 300 rounds.Yeah I know I'm into pressure but I've ran this load for over 300 rounds and never had any issues that concerned me. But yes after this I will back it down a little. This load shot so good which was why I was ok with the pressure I was seeing.
