RE: Traditions Buckhunter Inline Pistol
What did the former owner use for best accuracy?
Did he give you the owners manual to read about powder volume restrictions?
I know the first batch that came out around 5 years ago were deeper rifled 1-20" twists suited better with lightweight conicals. The new ones this year are shallow 1-28" twist better-suited for sabot/bullets.
Make Smoke - Not War with those using a different style muzzleloader than you.
