Over my 15 years in re-enacting, I have seen thankfully few injuries. Most of these seemed to have been caused by carelessness or excitement, but a couple by alcohol or other mind-altering substances.
My battery will not hesitate to pull our guns off the field if we think an event is not safe. I scouted one event near me this season to see if it would be worth adding to our schedule next year, but I am vetoing it because of the carelessness and drunkenness I saw.
When we do soldiers’ grave marker dedication services, I’m always impressed with the Parrot rifle firing its three volleys accompanying the seven riflemen. The black powder smoke really drives home the experience those men (of both sides) experienced, especially realizing most of those men walked upright right into the ranges of those weapons.
