RE: opinions/experiences with Ruger M77 MkII 8mm????
Forgive my ignorance but I never knew Ruger ever chambered a rifle for the 8mm? I assume you are talking 8X57mm?
I've owned several of them as German military rifles and Ican tell you the 8mm is a fine cartridge...especially if you reload. Unfortunately it's never been a popular cartridge in America which may hurt the value. Not a lot of people jumping up and down to buy an 8X57.
