Re: 6mm Rem help !
If it is a Ruger m77 Mark II then MidwayUSA has several choices for you to consider. Bell and Carlson, Hogue, and Ruger Factory stocks as well.
If it's a Older Ruger M77 they have stocks, but they are a little more expensive and most have to be special ordered.
Get the trigger tuned, well worth it and cheaper than a after market.
