I have taken a few animals with 140 accubonds and triple shocks in my 7mm stw, and up close the accubonds make me nervouse. They loose alot of weight very quickly. Take a quartering to you shot at 60 yards on a giant bull elk, i would much rather have the Barnes. This past year i shot a muly buck at 520 yards with my 7mm stw and the 140 xxx. There was a .284 entrance hole and silver dollar exit hole, the buck dropped in its tracks with a high shoulder shot. I have loaded the triples in my 270 weatherby, 7mm stw, and 300 ultra, and they have been accurate and deadly. I have been able to achieve under moa in all of the above mentioned rifles. Slow that accubond down abit or stretch the distance and you should be fine. I would go with the xxx unless your rifle doesnt like them. Cheers!
