[QUOTE="jsthntn247, post: 537129, member: 14894"] I have been developing a load with my 7RM with 24" barrel. When I shoot groups above 68 grains of h-1000 with a 162 SST I might put 4 in one hole then one or two off close to 1 inch in a random direction. My velocity with 67.9 grains average 2938, 68.2 2948, and 68.5 is 2945. While doing a ladder test, 67-68.5 grains only had .15" of vertical at 300 yards. So, I did a OCW test with 67.3-68.5 yesterday and below are the results. It appears to me that the OCW group is at 67.6 which has a avg velocity of 2930. Two part question do you think the OCW group is 67.6, and since my velocities level off after 68.5 am I getting unreliable powder burn which causes the fliers???
