Yeah thats the UM that I traded him for the Lightning. I had excellent groups with the 460grn Bullshop with 80grns of T7 fff and no wad. It is on the heavy side but it sure shot real good. I bought it and the synthetic stock at the same time from Sportsmans Warehouse. I ended keeping the syn stock. I've shot my KRB twice now and it is showing some impressive groups with the SST in the 300grn. By the way I lived in Queen Creek AZ for 19 years.
