I have a Savage, chambered in 300 RUM, 27" heavy varmint contour 1:10 twist. No Brake. Its in a Savage BVSS laminate stock. Leupold vari-x III 6.5-20x40. I shoot from a front rest with a sandbag top, and a bunny ear sandbag under the butt stock. Its a pretty stable rest for my 30BR. I was shooting 200 gr SMK's over a stout charge of IMR-7828 the other day. Problem: 4" groups at 200 yards (longest my home range goes). The gun is literally jumping 3" off the front rest, and torquing to the right, I'm thinking this ain't doing much for accuracy. What will help the most? New stock? brake? (who makes a good one for a RUM?) What bench technique works the best- -what do you do with your off hand? Presently, I grip the rear sandbag with it. wondering if there is any thing I should be doing with my off hand to help.
