I been using the Accubond exclusively for the last 2-3 seasons. I've shot a fair # of animals from deer to caribou. I use 140 grains in a 280, 165 grains in a 300WSM, & 180 grains in a 300 Win, 300Wthby, & 300 Rums. I have been very very impressed with the Accubonds overall performance. The 165s out of the 300WSM has been flat awesome on deer. I think I have about 6 deer taken with it. 4 were bang flops and 2 ran 40-50 yards pumpin blood. I've recovered 1 bullet. YMMV 163bc
