I have had two Ruger rifles a M77 Ultralight in 308 and a M77 in 300wm. The 308 shot about 1 3/4 but it was a Ultralight and the barrel was pencil thin. The 300wm is pretty accurate the best is a little under one inch for five shots with Rem Safari with 200gr Swift A-Frames. The only problem was that the first shot from a clean barrel will be about one inch low and 1/2 in left.
