There is your problem, in my opinion, the tighter the sabot the tighter the group, in general. Too easy or not seated well enough or barrel to hot you will get "blow by", which causes inaccuracy. I like that 250 SW group, and I would work that some more, switch to the black supplied sabot instead of the lo-drag or buy some MMP12s and Harvester Black long sabots and try those. A small sabot change can make a HUGE accuracy gain. Best Wishes
