Bobby Hoyt does a tremendous amount of rebore/rerifle and reline work. Mostly big bore stuff in the muzzle loader field. He might be someone that could help you out.
Very well spoken of around the BP forums, ect and has been at it for a long time.

No website or email.

Contact info (this is up to date and a new address & #'s as he just moved in the last few months)
