hello , new here . saw this site on you tube and was impressed by how knowledgeable the guy was . not real into muzzle loading , would like to hunt with it again but cant make it shoot good so i'm here to pick brains, I have a TC Renegade in 54 cal. seems to be a dead cal. as far as being able to find ammo. I put a scope on it as my eyes aint what they used to be. shot 20 maxi's thru it today and it wont group. I'll get two good ones and the third goes to china. when I got the gun 30 years ago it was deadly accurate and for the past 10 years ,off and on, I cant make it shoot rite I would like to try great plains bullits as I've heard that gun likes them but cant find them anywhere .any help would be appreciated thanx Mike
