Re: McMillan on a Ruger M77?
I just saw this question. Have three tang safety M77s. Two are short actions in the discontinued ultralight stock. One the 338 RCM has a #2 lilja the other is a 284 win made from a 7 rem magnum takeoff. Neither are bedded. McMillan told me at the time this design didn't need bedding.
Third rifle is a long action in 257 weatherby with a 28" #5 Lilja. Had that one bedded but no pillars.
All three shoot 1/2 MOA or better.
