Has anyone every actually done this on purpose to verify it happens as it's said to? Do you have video?
To believe is one thing. To understand is another.
I will never buy the line "We've never managed to make it happen in a lab but I SWEAR it's true!"
I hearken back to the days when "everybody knew" that soldiers in formation should break step before crossing bridges because the harmonics of that many boots in step with one-another would destroy the bridge. I'm sure that was in a field manual somewhere (like this business is in ABC's of reloading) and I'm sure there were lemmings-a-plenty to defend it without asking for proof (the Wisdom Gods of drill and ceremony wrote it just like the Wisdom Gods of munitions wrote the ABC's of reloading). But such a thing has never been proven and as such was eventually dismissed.
Now, I really want to get to the bottom of this one (and believe it or not haven't made up my mind on it). Anybody's personal KABOOM experience is irrelevent unless they did it on purpose.
So can ANYBODY please show me where somebody INTENTIONALLY managed to destroy a test weapon with an undercharged cartridge and succeeded?
PLEASE DO NOT CONTRIBUTE IF: You saw a gun blown up by accident and THINK it was due to an undercharge. That is supposition and irrelevant.
