Congrats on the turkey...I'm still chasing them down here in NC...

As Cay mentioned, flintlocks are much easier than most realize...This was the common form of ignition for at least 225 years, longer than any other...

I did notice a couple of things...It looks like you have a cut flint in the jaws...Find you some black English gun flints, they are the most reliable...It also looks like the touch hole is a little low on that gun so you will have to experiment on how much pan powder works best...When I make a flinter I put the touch hole high so the heel of the pan keeps powder from filling the hole...

I would also recommend real black powder...If possible FFF Goex...You can use FFF as both the main charge and the priming powder...

Finally...Use only cotton or linen for patching...I prefer to buy in bulk and lube as I need them...When working up a load, keep an eye on your used patches, once they start burning accuracy goes to pot...
