Like you I got a real shooter, and though I have not tried groupings at the distance you have, it does better than I can. I do not believe that it has ever had a factory round fired in it. I have used the 165 gr. SPBT for many, many years and had excellant success with it. It sits over 3031 and shot through either mine or my two sons rifles, has taken many deer effectively. I believe the rifle to be a real testament to John Moses and the company that makes them.
