Lucky for him, his fur hat didn"t catch on fire from all the sparks flying around.
I shoot my right-handed flintlocks left-handed. Even with safety glasses on, sometimes I get sparks, pieces of flint, etc in my face and especially my right forearm. But I wouldn't give them up for anything, very relaxing shooting at the range.When I was in the 10th Regt. of Foot in 1970s, the flash from the pan scorched my bearskin cap a couple of times. I made the mistake of "aiming" with my head too far forward instead of "presenting" when I fired. Maybe too much powder in the pan as well.
