I think that at least one other poster said that past a certain point of action strength the weakest link becomes evident and that is the cartridge case- couldn't agree more. Many of the better single shots, maybe some of the newer levers and most of the better bolt actions are probably stronger than the brass cartridge cases they house for firing. At that point it becomes a matter of gas management... which opens up another point for discussion. Again, I prefer not to find out first hand! The small ring Mauser I attempted to blow up on purpose didn't come apart like a cheap suit- just scattered a few small parts and splinters around. According to the high speed video recording, the largest piece was the extractor flying off to the right side and to the rear. But, the orange plasma ball of roughly 2-2 1/2 ft diameter that surrounded the action, at firing, would have been the greatest threat to the shooter. This was done in an open air bunker and the sound was very unique. Not a big "boom" like many would suspect but more of a muffled, high pitched "crack"- not unlike the sound made by detonation of a small charge of high velocity explosive.
Reload with respect for the potentials and with full attention to detail.
