i put this 1.75-6 x leupold to replace my other scope on my # 3 as this rifle shoots great groups. the load is 50 grs H-4198 with a 300 gr hp bullet that cronies at 1900 + fps, i have shot heavier loads, but this load is just plain accrutt. under MOA and kills like chain lighting. this three shot group was the last three shots at 100 yards from a lead sled, i will make a very small adjustment before hunting.
