Best- CVA Wolfe. Bought it at a Pawn Shop, with scope, for $80. It would shoot anything, cast minnie, sabot, round ball, and keep 3 shots in a 3" circle at 100 yards all day long.
Worst T/C Encore 209x50. It was an absolute tack drive, sub MOA accurate, with one, very exact, load. If you cleaned it after every shot. Took me weeks to find that one load. Anything else, especially cast minnie balls, the groups looked more like shotgun patterns.
Sad thing is I sold the Wolfe so I could buy the Encore. I wanted a "real", "name brand", "high quality" muzzleloader.
