I am contemplating purchasing a Ruger M77 MkII in .300 Win Mag but the owners of a local gunshop said that when you purchase an m77 MKII you have a 50/50 chance of getting one with poor accuracy. They said that Ruger only has a 50 yard test range and they only guarantee 2 inch groups at 50 yards. That means 4 inches at 100 yards and 8 inches at 200 yards. If true, that isn't good enough! They also said that if you have one of the bad ones you can send it back to Ruger and they will recrown the barrel but that is all they will do. Could anyone tell me if this is true? They also said that original M77's didn't have this problem.
