I took the new Extreme with the MHC barrel out today and put about 35-40 rounds through it. I used the 250 grn XTP's, 250grn sst's and the 300grn sst's. I used anywhere from 80-120grns of RS and T7ffg. Standard Win primer. Knight sabots, Crush Ribs, and the low drag sabots that come with the SST's. My best group from 50 yards on sandbags was about 2 to2 1/2 groups. Not terrible but I was expecting alot better. My new Omega with the Laminated TH stock first outing was stacking the shots on top of each other at 50 yards. I wont use the Barnes or Powerbelts because of the price. I shoot 2-3 times a week. 4 power scope was used. Any ideas especially with the XTP's, SST's or Gold Dots?
