I am in possession of a 1974 Ruger 77 that is a bit lose of bore. I does not group great , but has a knack for dropping the first shot cold bore on a 1.5 inch orange dot every single time. I load a 160 gr nosler ahead of IMR 4831, 160 gr sierra bt with same , a 140 gr. nosler partition with H414, and the super plain vanilla load of 48 grs of IMR 4350 with a 150 gr. CoreLokt for 2650 fps. The last load is the only one I have ever used on game, but killed a raghorn bull at 150 yds. like it was a bigger gun............
