The good old military way of avoiding silly things to happen, it to make it fool proof. Not difficult to do wrong, but totally impossible
Like having the same type of fuel for planes, cars, tanks and even cooking apparatus. Come to think of it.. I have some cloudy remembrance of a drink with the same name as the fuel in some military bars, F34 they called it.
Anyway, I think it's quite amazing.. 1, that it's possible to leave so much lead remains in the barrel that it makes a significant obstacle. 2, that it's possible to make so weak loads that it does not even spit the bullet out the barrel, with lead or not.. 3, that with all the sparks, smoke and other alarming signs, trigger is still being pulled. But Iâ??m still quite new when it comes to pistol shooting..
