7mmRM for the most part with the 270 Weatherby Mag in close 2nd place (it's a hot rod) not a target gun. MB
My 270 Weatherby is a Mk V Sporter with a 24" barrel, I could not get it to shoot well with 130 gr bullets so I tried 150 gr Hornady SP's and a max dose of 7828 with Fed 215's of course. Really nice tight groups at 3150 fps and I quit experimenting right there with it, deer and antelope deluxe performance. MB
