While I have not used the AccuBond exclusively, I shot 4 head of game over the past two seasons with them [used Partitions for my elk and mule deer, 30-338 for the Elk, 6mm and 270 for the deer] I recovered only one, that being a 140 grainer that I took a 190 lb Muley buck with. The rifle was a 700 Mountain chambered in 280 Remington. I started the 140AB at 3050, and the shot was about 200 yards. The presentation was quartering away, and the bullet entered just in front of the last rib, and was recovered hanging out of a hole in the hide on the point of the offside shoulder. Basically a bang-flop. Recovered bullet weighs 112.5 grains, and is a classic musroom, despite breaking some bone. Did not lose a lot of meat to bloodshot. Second animal with AB was a 250# black bear, same rifle, same load, broadside through lungs at 165 yards. Complete passthrough, Bang-flop also. Exit about 1½" in diameter, lungs were mush. Third animal, another Black Bear about 280# Broadside at 100 yards, 200 AB out of my 8x57 Model 700 "Classic" It starts at 2700, and passed through the lungs easily, leaving a 2" exit, instant Kill. Lung damage again quite extensive. Finally, a Bull Moose with the same 8x57 load and rifle, slightly quartering away at 275 yards. Bullet punched right through both lungs, breaking a rib on both sides, and exited, leaving a 2" exit. Meat loss was negligible. Moose died where he was standing, never took a step. I was impressed, since moose are generally not quick to tip over, and will usually stand there for 20-45 seconds before falling down, or perhaps take a couple of steps before falling. Since Partitions have been so good for me over the past 40 years, they will remain my go-to bullet, but so far the AccuBond is looking like a winner. This fall, I will be using them again to see how things go. Regards, Eagleye.
