I own a M77 and know several others who do as well. All the Ruger rifles I have been around shoot well. Some may be picky about the type of loads they like but the same can be said about any rifle.
Two of the guides I have hunted with say they've seen many Rugers that deliver less than consistent accuracy and they would not have one.

To me this is not good evidence that a Ruger is not accurate. Being a guide does not make one an expert on Ruger accuracy or lack thereof. There are too many variables in such a broad statement as that: What was the level of accuracy of the shooter? How well had the gun/s been taken care of? What was the consistency of the ammunition being used?
