Paul: If you are having some delay in your ignition, hang fire you might be using too much powder in your pan. Some will disagree with me on this but it might be something to try, using just enough powder to come up to the vent hole.
It shoots with about 1/3 of the pan full and banked sorta to the right, not up against the touch hole. I purchased a different touch hole pick as the one I had didn't go all of the way through to the main charge. The clue was that someone handed me a hat pin to clear the touch hole, that was the ticket! Works better that way. If I use 1/4 pan full with a dull/rough flint, it misses occasionally.
I have been using a .50 inch diameter punched leather piece to push down the powder, placed above the powder and under the ball/patch. Just something to test.
I tried 50grs of Goex FFFg, .445 RB's, blue tick patch, shoots a bit better. The crown needs a bit of a touch-up to smooth it.
So far the flints are lasting about 25 to 30 shots each. I have re-hardened, using Cherry Red, the spare frizzen today after range time and will see how that one works, later. I was told not to draw it down to see if that works better and eliminates the flint/frizzen gouging. I only heat the upper (vertical) part of the frizzen during treatment.
I also tried placing a thick piece of leather under the flint+leather combo to raise the flint a bit, that helped a lot. Got the flint to hit above center of the frizzen. It seems to shorten the perceived "delay" a bit.
Thanks to all,
Paul
