I know this might belong in the inline section if so sorry. I had a 50 cal encore barrel that I had bobby Hoyt bore out to 54 1/ 66 for round balls finally got to shoot it yesterday I really wanted this rifle so I could use a scope. The barrel shot 1.5 inch group at a 100 with 85 grains Goex 2f. I've read on this fourmn that members had a hard time cleaning real black in a inline well I did not my encore barrel was just as easy to clean as a sidelock. I real like having a inline round ball rifle.
