I do French and Indian War re-enacting, and We don't point directly at anyone ever! In long guns (muskets mostly) we use about 100 grains of FFg in a paper catridge. The first load is torn open, and the loose powder poured, with the paper (newspaper) rammed to hold the load.
During a battle no more ram rods are used and so the 2nd and so on loads are torn and poured, but no paper or ram rods are used ever again after that first loading.
Some re-enactors thump the butt stock to settle a charge, and many prime the pan from the same torn paper first.
Some swat the gun to level the prime in the pan as the weapon is shouldered.
In case there is a camera shot close up to someone designated to shoot at the camera USE Lexan, or prepare to be sued by the camera man who will be seriously hurt.
Blanks are not safe!
No weapons should be fired closer than 50 yards away from any opponents.. If so be prepared to be sued..
No rammers allowed after the first loading, and there should be the equivlent of a Range Officer to check. He should also check the locks. At 1/2 cock the gun should support it's own weight, by hanging it from his finger and he should jounce the weapon as well.
All guns should be in good working order. No guns should be loaded before passing these tests..
All events I know if require a frizzen stall, which is a leather pocket on a thong, that lives on a frizzen any time the gun isn't in direct use, ie: marching whether or not the guns are charged and whether or not the frizzen is open.
We are also required to use a pan shield, or a guard, which insures nothing, but may tend to dorect the vent blast up, down or to anything but the side directly, but that doesn't mean the guard will really preform what it is intended to.
