Just saw this and though WT... I started out, long, long ago in PA hunting that BP season with a T/C flinter and RB...
Once at the range, after reading a Siefried (?) article on line, I drilled out my "touch hole liner a skosh" and on one shot, I got to jabberin with another shooter and forgot to prime the pan...
When I touched the Go Trigger, it Went OFF quick like usual...
I'd replaced the T/C frizzen with a Lyman and used Knapped flints but it was interesting, cause in PA (at that time) a Flinter was NOT considered "LOADED" till the pan was charged...
From then on, I used a feather quill in the touch hole and made sure on the trip to my hunting grounds in the dark, that the gun muzzle was pointed rearward in the covered truck bed, and never cocked...but a main charge and ball inserted at home in good light, just cause I no longer trusted it was SAFE to rely on a pan charge to cause ignition...
