So I have added a 50 cal. Barrel to my encore line up. I am shooting black horn 209 100 grains by vol. CCI 209M. I have had one hell of a time getting these barns bullets to slide down the barrel. Don't get me wrong I can get them to seat, but only after what I consider a bit of a fight. I called TC, and much to my pleasure they were very helpful and great to talk to. So after a bit of conversation I've found out that TC barrel tolerance can be a bit to tight sometimes. Also with that being said the barrels on the encore prefer a .451, but not much more than a .452. TC was more than happy to lap the barrel at no cost, but something valuable I learned here was some muzzle loaders have a very specific load set up. Almost as if it's own identity when it comes to powder, primers, and bullets. TC said to do some research spend some time shooting different load set ups. They also recommended getting down to the wire and verifying bullet size, as some mass produced bullets may not always come out the same size. Anyways just thought I would share this with y'all. I thought the whole thing to be very educating, cause I simply don't know everything I need to know about muzzle loading.
