I've watched a bunch , he's the reason, a few years back, for my swollen cheek...
I didn't know much about smoothbore shooting and he was recommending 100-120 gr of powder for accuracy.
Sooooo I loaded up my .62 Virginia Fowler with ball and 100 gr of 2f and headed off to the fort shoot at a local rendezvous.
After a few dozen shots my right cheek was so puffed up I looked like a chipmunk 🐿️.
Lesson learned , it left like I was touching off a howitzer by my head.
I still like him though. No harm no Fowler, ha ha
