The stock on the Ridge is a POS.Easily bent to touch the "free floated barrel".You can get good 3 shot groups,but after that they open up
and that was with their #5 barrel.
This may have solved my mystery. I bought a hunter in 6.5 CM a couple of years ago and it shoots great. Recently bought a Ridge in 308 expecting equal or better accuracy but it ain't quite as good. The stocks are the same, but the heavier barrel of the Ridge may need a bit more clearance. I hadn't thought of that. I'm gonna open up the barrel channel and see what happens on mine.
And FWIW I can easily bend the McMillan stocks and factory wood stock on any rifle I own enough to touch the barrel. But with enough clearance it simply never happens under normal use.
