[QUOTE="tobnpr, post: 2415542, member: 68758"] I'd ask the smith to borescope the throat. Could still be pretty substantial erosion after 150. A lot of "ifs"... If it headspaces correctly- or headspaces short where the shoulder can be set back without needing to mess with the chamber itself would be ideal. I'd be reluctant to rechamber a barrel that shoots that well unless there were a good reason for it. At the same time, the chamber was obviously cut well- so "following it" with a reamer to deepen it shouldn't degrade your accuracy. A slight setback to clean up the throat completely would basically get you back to a "new" barrel. Headspace can be checked/measured without needing to do any work to the barrel, so I'd pull it and take then tenon/PD dimensions, and measure shoulder to gauge length and see what you're working with. Just my $.02. Good luck with it, let us know how it goes. [/QUOTE]
