hello and welcome to the site from Ohio. Grandpa, I've hunted the Clearfield, Duboise area since 1974. While I archery hunt the rut during the first 9 days of November and follow that with late season flintlock hunting. I have not hunted ML in the early October season. I'm thinking you need to start some shooting to get used to the slight hesitation of a flintlock due to the pan firing the main charge is slightly slower than an in-line ml. You will need to get main charge powder in 3f , and also priming powder in 4f grandulation. I prefer real black powder for flintlocks and it might be messier to clean up I like the traditional part of using flintlocks and black powder. You're going to need to know what rate of barrel twist you have ie 1-28" for conical bullets, 1-48 for either a round ball or conical or 1-70" for patched round balls. I'd start with 80 grs of 3f powder and keep the priming pan filled only about 1/4 not to cover the touch hole inlet to the barrel. For round balls go with a 490 gr ball and a pre-lubed tc .010 patch. If your rifle shoots conicals then something like a Buffalo bullet or TC maxi-hunter for 50 cals would work. . As far as flints try TC sawed flints as they seem to strike a good shower of sparks and seem to last longer than black/yellow real flints. This is some random thoughts for now, ask anything you want and somebody will help you! Good hunting.
