I haven’t shot muzzle loading revolvers for forty years! Same reason. I do shoot muzzle loading and cartridge rifles with black powder. Much easier to clean.
I still have a Thompson Center flintlock rifle I bought in 1973. Never fired it as a flintlock is a booger to clean.
On the other hand, my Lyman Great Plains rifle gets shot ever so often. I rigged up a simple holder to both shoot and clean it quickly.
If you can shoot a flintlock accurately, you can shoot anything.
The firing lag time is hard to get used to.
The pan whoosh!
Then the bang!
I’ve had the Great Plains rifle, 54 caliber, for 25 years. I call her “Ole Betsy”. Love it! Taking it elk hunting this year so when I jump them in their beds I can get a shot. Follow up shots with a S&W 629, in 44 mag ... Ole Betsy takes a while to reload.
