It may be too late to help Tannhouser, but I am about to rebarrel a model 10 and could use some advice. It is a 308 and has been an excellent shooter until now when it isn't. I have it in an MDTs stock and use the rifle for .308 days at Mifflin Co where it can (could) ring steel at 1,000. So what I am thinking is everyone should have a .308 . rebarrel in an upgraded .308, definitely threaded as it isn't now and spotting shots is pretty difficult inside 700 yds. It currently has a 24" barrel and that seems adequate, especially as a brake will push it to about 25.5. Still it looks like 26" barrels are what is most likely readily available. I'm looking for a really good barrel as it will regularly be used for long range work. Any thoughts appreciated.
