We did our part with colgaffneyis for Minnesota’s Tartan Day observance. IMHO, this is a rather artificial celebration, not having any historical precedent. Still, it is harmless, and there are many other such things going around, and it was a chance to do stuff with friends, so I have no problem with it.
Actually, not completely harmless. Four of us carried matchlock muskets, and we fired a couple of blank volleys as a salute at the end of the ceremony. I had a misfire on my second shot, and got a burn in my left palm for my sins And they were my sins: I don’t fire these things often, and I had not reviewed the procedures for loading and firing them any time recently. Black powder is an old explosive, but is still very dangerous, especially with an inherently hazardous device as a matchlock musket.
