I'm just gradually working my way through all the same types of hunting I've done for decades with modern high power rifles and shotguns which I never use any more....the challenge is to do it all with Flintlocks...deer, squirrel, rabbits, doves, ducks, crows, groundhogs, coyotes, etc.
IMO, there's really no challenge to using the modern high performanmce stuff wearing scopes, etc...no different than using my Remington 700/.30-06...that environment is simply a case of "if I see I can kill it".
IMO, real muzzleloaders put the hunt back in hunting, and particularly hunting with Flintlocks.....great sense of satisfaction & accomplishment to take game the way our forefathers did when they settled this country...and the irony is since I've had to really re-learn how to hunt, I've taken all my best bucks with Flintlocks...including a couple of magnificent 10-pointers I never would have seen / taken otherwise.
