I'm sure that the Accubond is an elk killer. But the Partition is the way I go when I'm after racked elk. I put 1 160 grain Partition through-and-through the huge thorax of a 900+ pound bull last Sept. He died. Quick like. As in dead. Scored just under 374. A game warden yanked out two of its lower teeth, took a look an 'em, and told me that my elk was a good 10 years old.
I wouldn't think twice about hunting the largest moose in North America with a 150 grain Partition fired from a .270 Win.
BTW, I up and sone bought 2 boxes of Accubonds for my .270 Win. I might use 'em for elk hunting this season. But I might just save 'em and go with 150 grain Partitions. For some reason, I don't much like changing what works.
