I do not know if this makes a difference or not but, there is a pattern on all the groups except for the first one. Target2,3,5, and upper left one also have 2 higher to the right and then two lower to the left from those. Now it happened in that order on all 4 of those groups, the first 2 rounds are upper right and the second 2 lower left. What does that mean? Is it a gun issue. I thought maybe it was me but given 4 of the 5 groups were patterned very similar I am leaning to a gun issue. I am using the same pattern of shooting about 10-15 seconds between each shot. Any Ideas to all you bench shooters? I am a hunter 1st a tight grouper second and have never really done this type of a load developement.
