Is finding that perfect load. I am not there yet but have two loads that shows I am getting near. Best group is .450 and next is .650 three shots. Rifle is Winchester model 70 Supergrade, cal 338 WM with a Burris 2 X 7. So far I have tested five factory loads and 22 different reloads. Used six powders and five different bullets. Bench rest at 100 yds.
Best load is on the right target below.
