I have never blow one or seen one blow by accident..Have pruposely blown up some milsurp rifles in tests...

I have blown some primers big time and once blew a primer out and lost the extractor on a M-70 pre 64 by using a misprint in a loading book...Had to hammer the bolt open, thats about it for me...

Blew the clip out of a .45 ACP 1911 custom and shattered the grips, left my hand nummer than a board, and throbing like a old time cartoon...The custom smith had throated it out a bit too much..He fixed it, I sold it.
