My flintlocks are the newest household acquisitions after many years of gun ownership and sport shooting interest. Suffice it to say there a lot of guns in the house. Some "senior" Winchesters, Marlins, Springfields, Colts, Mauser's, and some newer S&W's, Springfields, Kimber's and numerous "cowgirl"" replica's. There are only two loaded and both are in separate locked gun safes as home defense weapons. I never assume any of the "modern" guns are safe and unloaded. But with the flintlocks I know they are not loaded. And I know when they are loaded and I feel less danger handling a flintlock than handling any of the other "unloaded" guns. But the oddity apparently is that carelessness in handling a flintlock, such as burnt noted above, can be equally dangerous. Fewer accidents happen PROBABLY because fewer people shoot BP. Wonder if there are statistics on injury numbers per BP shooter vs injury per modern shooter? No question about following ALL appropriate safety procedures with any firearm...loaded or "not". As I move around the world of primitive firearms I do hear of some who have "misfires". But it seems far less of a complex picture to solve that trying to "fix" a semi-auto 380 which ALWAYS jams on the second round in the magazine. (Not mine, BTW.) If you get sparks and a pan flash it should go off unless there is an obstruction in the touch hole OR the breech...something has to be between the pan powder and the charge or maybe the powder is bad/wet. A friend had a replica that would not regularly fire and no one could figure out why. The individual who did figure it out simply cleaned the gun very well and got a ton of $#@* out of the barrel. Secondly, he drilled the touch hole and inserted a liner of proper size. It has not failed to fire since. As to the 380, no one has that figured out yet. (But I don't care!)
I cannot remember when I last fired a modern firearm. Maybe I need to seel them and get more flintlocks!
