Our family hosted a black powder club on our property when I was growing up. I was around BP shooting/rendezvous all the time. My first rifle was a TC Hawkin and that is all I had to hunt with my first 4-5 years. I started shooting ML shotguns when I was about 16. It was an old Brown Bess replica.
In muzzleloaders, I have 2 flint rifles (36&58cal), a 1840's vintage English percussion 13ga. single barrel w/rifle barrel, and 2 English percussion doubles. I still shoot them frequently, and compete in sporting clays at Friendship with the single and both doubles.
