This I agree with. I would bet there isn't a gun make that somebody somewhere hasn't blown up at some point
None of us know for sure what caused it, we are just guessing and some may be better guess's then others.
The OP has stated that he likes to push it when it comes to the load. When you do this you may or may not like the results you get.
A wise man once told me that if you do not want to hear the answer then don't ask the question.
The best thing with this is that no one got hurt, end of story.

I am the original poster and I never said I liked to push it when it comes to the load in fact I keep it at the starting load as I have no need to go faster.
