I went to the range today to do a seating depth test for my wife's 6.5-284. I had three depths .015, .030,.045. The only one that shot good was .015 off lands. At 100 yards it shoot 4 shots in a dime. But the SD was 29 and ES was 13.2. Does a guy just stay with this group based on group size and leave it alone ? Or is the sd and es to high and start over or tweak ? I don't know what to do at this point
