RE: Ruger 77 6mm?
A quick look at the Remington or Federal website will reveal what loads are available. There is no need for us to list them for you.
You can expect the caliber to be a superb performer that fits in nicely between the .243 and the .25-06. I havne't had a new production M77 so I'm not sure what kind of accuracy to expect. I do know I have a healthy dislike for the three position safety. [:'(]
