So I bought a Lyman deerstalker stock, Lyman hunter lock, and tried mating them with a TC Pennsylvania Hunter barrel I have. Got the lock in with a little bit of work. Had to fit the TC tang to the Lyman breech. All to find that the hammer barley catches the rear lip of the nipple. After reading about frankenguns I thought I would try one. Anyone run into this problem? Ideas? This is a project for a loaner rifle, if I ever get it figured out.
