davidlandrum - I had not noticed wildly excessive fat on these animals, but they were large mature bucks in a very cold part of the world. Fat plugging is certainly a plausible explanation.
m&m - My interpretation of the literature is that the Accubond (AB) fits between the Ballistic Tip (BT); rapid expansion at the expense of penetration, and the Partition; deep penetration at the expense of expansion.
The AB is touted to have more controlled expansion than the BT, yielding better penetration, but not as much penetration as the Partion. This is accomplished by using a thicker jacket, and "bonding" the jacket to the bullet core.
I guess for me the bullet performed as advertised: plenty of pentration and expansion. I was just puzzled by the lack of blood, which would be hard to blame on the bullet. Maybe I need a .45/70
