My experience with Accubonds is limited to shooting 3 deer with 110 grainers out of a 257 Wby. They are OK as long as the velocity is high and/or you hit significant resistance.
Expansion and resultant tissue damage seemed minimal at long range even at 257 Wby velocities.
In one case, the approx 175# whitetail took a high lung hit @ 365 yards w/o apparent notice. As he turned and walked away, I sent another @ 380 yards which clipped his right hind quarter, entered the paunch, and traveled forward exiting just behind the opposite front shoulder. The buck walked out of sight but fell within 30-40 yards of taking the second hit.
The first hit produced only moderate lung damage and left a small diameter exit. The second hit did significant damage within the paunch as expected but again, only minimal damage to the lung and another finger sized exit.
Fortunately, the deer was in thin cover and easily found but under different conditions this sort of performance would have been problematic.
