One thingI learned a long time agois that a load that shoots sub moa at 100 doesnt doesnt always equate to tight groups at longer ranges. In my case, I am not that big into tight groups but the rifle better shootto POA.
I just shot these last week at 500 yds with a.308 win, not the best that the rifle has shot, 96 degrees 5mph crosswind. Aiming point is the black dots. 5 shots on the left, 3 in the middle and 3 on the right. The 5 shot group was the last one shotand I totally blew a good group with the fifth shot. Oh well that's shootin, theyall wentunder moa.
Shot this 3 shot group with my 25-06 Cooper at 500yds recently. Point of aim is the middle of the cross. Measured slightly over 1 1/2 inches.
