Re: M77 Frontier build
Rugers can be built but. . . . a lot of smiths don't like to work on them, they are more difficult to set up in a fixture to true them because of the design of the action.
The aftermarket support leaves a lot to be desired for Rugers as well.
They can be built but it takes a little more effort.
I think the Ruger action is a solid action and I like the controlled feed mauser style bolt.
The angled action screw requires a little bit of planning when you bed it.
All in all if you are willing to put in the work and find a competent smith who is willing to work on them, you can have a solid gun built off of the Ruger action.
If you don't want the hassle you can build a winchester, remington, or savage a bit easier.
I have a 300 WM M77 mark II with a shillen barrel, H-S precision stock, Timney trigger, and Murphey precision picatinney rail. I regularly shoot steel at 1K, and this spring I hit a 3' X 4' steel target at 1 mile. I shot my antelope at 657 and 476 yards this fall with it and a bear at 352 yards last year.
