the 155 might be slightly more accurate and faster at 300 or 600 yds, but the heavy, will have more knock down power in both cases. Thanks to all who commented, but I've made my decision, and my barrel has done most of that for me, the 190gn Hornady BTHP is the most accurate to both distances and most energy at target, and seated at the lands, at only 2640fps.
