Just chronographed my Gap 308 semi auto with a 24 inch Bartlein barrel. I used 44.5 gr. of Re15 and 155 scenars. Velocity averaged 2750 fps. Is this typical or should I try for more velocity? My groups avaged less than 1/2 moa. Is this velocity enough for 900 yards? Thanks, Lance

    Out of my AR-10 ... I can't get them any faster without destroying my brass.
