Well, I shot this rifle and as it turns out the flintlock pan and flash hole don't match up correctly.
It takes 4 or 5 times of priming the pan and firing it to get it to fire the charge. The flint throws plenty of sparks, the pan charge flashes very well and 4F is what I'm using.
I talked to a local friend that has worked on this rifles for 40 years and he says he can fix it. He thinks it's a matter of lowering the flash hole in the thimble, to get a better ignition. Currently the hole is above the flats of the pan and it should be much lower.
The next issue is with me.
After spending over 2 hours with my friend that currently owns this rifle, I think I'm done with flintlocks, period. My local friend says he can easily switch it over to a caplock....and do so at a very reasonable price. When the rifle did fire, it was very accurate.
I'm going to have to think on this for a few days before making this decision.
* I'll either return the rifle, to my best friend. (it's on loan, until I decide if I like it or not)
* Have it switched to a percussion rifle and buy/keep it, from my best friend.
* Make an outright purchase of a new Pedersoli (caplock), in a Pennsylvania, Kentucky or Blue Ridge rifle.
Decisions, decisions...
