Welcome to the forum woodsman & snake-eye, I too was a trapper, I started trapping because I followed the mountain man era.
Back before asthma, I could out run, out drink, out cuss and out shoot any man alive...
I had the blood of a rattlesnake, my mammy was a wolf and my pappy was a grizzly bear...
OK, maybe I exaggerated a bit.
Speaking of bears, pratice reloading fast before you hunt anything that can EAT you... History is full of stories about bears that take 20 round balls and still keep charging.
Granted the bulk of them are grizzlies, but I hear a sow black bear with cubs will charge people.
I started out with a T/C Renagade flint lock in .54 caliber, the Lyman's great plains rifle will be a good muzzleloader to start with.
