I have had VERY good luck with Pac-Nor barrels.Don't be afraid to go with a Pac-Nor barrel,I had one on a 300 RUM in a very light contour and it shot very well. Plus, they are more likely to make you a stainless barrel in a light contour than some of the other makers. Broughton & Brux are two that worry about stainless in cold weather
I got lucky and found mine used in the caliber that I wanted!That s the one rifle I am still missing!-- A left hand nula 30/06! Can't afford to order a new one,still hoping to luck into a used one some day.
