When the accubond first came out and I got to see a few animals hit with it I wasn't impressed at first. But then rational thinking came into place. If the bullet delivers that much terminal shock within the first few inches of entering the animal but yet still carries enough weight retention to get to the opposite side of the animals body. That is one massive wound channel. As with most bullets there's bound to be a shoulder joint or some other large bone from a miscued hit that's going to show you complete bullet failure. Especially when your talking elk sized game.
I'm not promoting Accubonds. I just think they do okay. We all know what happens when you drive a plastic wedge back into lead. Your going to lose 30% or more of your bullet in the initial impact. This is what made the v-max bullet so popular with coyotes, it didn't have the weight retention to tear up the other side most times. It's the same with most polymer tipped bullets vs high velocity. For the Accubond it's built tougher than a v-max but the concept is still there. It does okay. In the larger calibers that are slower the Accubond creates quite a devastating thump.
Barnes was mentioned before I won't comment nor hurt anyone's feelings today.
