John Taylor has made an art of lining barrels. (Reline? Was it lined once before? Funny how definitions shift in our language.) I swear he could probably do one with his eyes closed. I know that he uses TJ's Liners as much as possible. TJ's are hammer forged and a tad more expensive than the more common Redman's liners which are button rifled.

Comparing prices between re-boring versus lining it's probably a wash, or close to it.
