My latest rifle, a M700 30-06 is just about as "good" as that M77 alaskan. Three different powders with the 180 partition have left me wondering what groups smaller than 3" look like. It has a ring about 1/4" back from the muzzle where the pilot on their crowning tool scored the rifling, and a large gouge in a land about an inch further back from that. Since it beats 6" though, from what was said above, it doesn't look like Big Green would touch it.
