Some one on this forum once said a Win Mod 70 is good for MOA at best because of its design. Mine stock from the factory in 270 WSM on its very best day could produce an occasional MOA for 3 shots until the bbl slightly warmed up. But since I had it re-barreled with a 26" Brux in 7mmWSM . Shooting the Hornady 139gr SST in front of 69grs of RE#19 . Producing 3300 fps I'm getting under 1/4" at 100yds and under 1/2 at 200yds. Barrel and re chamber job along with Muzzle brake cost $800.00 . Best money ever spent on a rifle.
