Big Sarge,
this will sound like a broken record to the rest of the guys, but I can highly recommend an 8 bore muzzleloader from Steve Zihn. The one I have actually feels light in the hands and is well over 10 lbs......I dont know how much over because I havent weighed it.....and is very pleasant to shoot. Dont get me wrong, it rocks and rolls, but doesnt bang you up like a modern magnum. Very addictive.
