I was talking to a guy at a party last night who swears up and down that he jams primers in hollow points to make his own explosive ammo. I told him I thought this seemed absurdly dangerous and while I don't know I would assume that they would go off in the chamber.
Old idea, it didn't do much 50 years ago when I first heard of it and probably didn't do much better when the idea was first thought up way back in the civil war days. Let the guy play all he wants, someday he will shoot the cat or the wife's jewelry box and lose his toys but it won't blow him up.
Good intentions will always be pleaded for any assumption of power. The Constitution was made to guard the people against the dangers of good intentions. There are men in all ages who mean to govern will, but they mean to govern. They promise to be good masters, but they mean to be masters.
