Your "flashes in the pan" prove that your lock and flint are fine. They fire everytime. All my flinters, save one, use a 1/16 touch hole dia. The other would not fire reliably until i opened it up to 5/64. In my opinion, 3f is much more reliable than 2f in flinters. And yes, i also prime with 3f. And no, i never pick the touch hole. I also drill the back of the liner out so the cone tip is VERY close to the outward facing surface of the liner. I use 1/4-28 liners and 5/32 bit for this. This moves the main charge closer to the prime. And i use maybe 1/2-3/4 pan full of prime. Hang in there Muley, it only gets better from here on out. Also, talk to anyone else at your club who shoots a flintlock, get their advice, don't be afraid to try something different. We've all started at the bottom and learned from there. Regards, Buzzard
