This season i used the 270g Gold Dot, and the crush rib sabot in my Omega. It seems to be a fine bullet for hunting, and is accurate in my rifles. I imagine the Triumph barrel is some similar to the Omega barrel. My Accura has a slightly larger barrel, and i used the Harvester smooth sabot with the 270g Gold Dot in this rifle. Nearest deer was killed at around 30-40 yard, and the furthest at about 230yd.
