A muzzleloader is the only rifle I use for Deer hunting. Instead of using the modern muzzleloaders I strictly use Flintlock Rifles. I use a .54 cal. Smooth Rifle and A .50 cal. rifled Barreled. When I started shooting them in 1977 the modern ones didn't exist.

Well, we must be dinosaurs! I dont use a flintlock, but do use a Hatfield semi-custom percussion (later Hawken replica) in .54 caliber and blackpowder. Have for almost 20 years now. Although I often use this during regular deer season also, I still like to use centerfires occassionally. Guys, there's nothing like the adrenalin rush with the smell of black powder and thick smoke in the morning following a shot while immediately analyzing your shot placement in your mind before heading off to look for your game! There is also the experience of the occassional hangfire with a nice buck in your sights and the frustration of picking your head up after only a click, only to have to gun fire a half-second later with the buck bounding off. But you just know that your ancessors experienced the same thing. There's just something about a truely primitive weapon that takes you back, like nothing else can!
