Which McMillan stock should I go with for the Mod 70 in 338win for hunting application? Am leaning towards the Supergrade model. In particular am interested how the different stock models might affect recoil and muzzle jump. I have only ever used it with the factory plastic which fits me fine. Now am just wanting to upgrade to something of better quality than the regular tupperware stock. I see they make the Hunters Edge for Mod 70, but only recommended for recoil levels up to 300win. Probably don’t need quite that light anyhow. Feedback appreciated. Thx
