I used the 160 accubond a few years ago on a bull elk. 3 shots on the ribcage behind the shoulder at a lasered 148 yrds. All 3 bullets blew apart and the elk had to be finished off at close range. I won'tuse accubonds on gophers anymore....Just my personal experience. For those wondering the load was fired from a .280 remington around 2800 fps at the muzzle.
