RE: most accurate muzzleloader????
Might just be a case of golden memories improving with age, but the most accurate ML I've ever owned was a 40 caliber, 40" barrel, somewhat "Kentucky style" caplock rifle I built with a Douglas barrel from Dixie Gun Works back in the mid-60's. One day back around 1980 I didn't clean it after a shoot. Left it dirty for months. It still shoots - but not like it did. DAMN ME!
