I bought a pedersoli pennsylvania for my first flintlock (same lock) and out of the box It had a few issues with short flint life and alot of pan flashes. I remedied most of it by reshaping the frizzen foot and polishing it to a mirror finish. I have also found that the small lock prefers ox yoke english flints over the tom fuller flints sold by TOTW, I find the ox yoke flints to be more consistentl flat on top with less of a hump. If needed I also shim the back of the flint up with a toothpick to get more of a scraping strike on the frizzen.
any more I average 40-60 shots to a flint on the little pedersoli lock before they are worn down to a nub, once in the nub stage i can use them in my flint basher of a harpers ferry pistol for 8 or 10 shots before they are completely used up.
