I have owned a bunch of T/C and Lyman guns over the years. All flints. None shoot great with patched round ball and my charges. By that I mean around 5-6" group at 100 yards. I currently have a Renegade with a .54 Green Mountain barrel with 1-70" twist. It loves a patched RB and 90 Fffg. My first goups with the gun cloverleafed at 100 yards. But the big 32" barrel is real heavy. But it helps with recoil. I just wish the Renegade had more stock drop as with the Lymans.
