I would look at Pac-Nor barrels, not cheap but not nearly as expensive as some.
If you don't have a favorite gunsmith, check with Kirby Allen, one of the
best Gunsmith's in the Nation in my view & his prices are like a local Smith. He re-chambered a Sendero for me from 25-06 to 25-06AI, skim-
bedded it, trued rec., installed a Holland Titanium recoil lug & re-crowned
it. It is now a 1/4" gun with very near .257Wea. Performance. His E-mail is kballen@3rivers.net
You won't be dissapointed!
