I turned a guaranteed 2moa rifle into 2" and under at 300 yards in less than fifty rounds.
But what's fun is I took my first elk at a ranged 400 yards with it before I put the brake on it. I knew the bullet would hit within 4" of the aiming spot. The shot was as steady as a bench because I had a hump or berm to lay behind with the rifle on the soft dirt. The 160 partition made a 6" bruise entering and a 3" bruise exiting. The top of the heart was exploded. The bullet hit at the bottom of the "group" if there was one.
