The Accubond and the Interbond both have a much higher B.C. They carry more velocity down range and therefore hit a bit harder. In my guns(30-06, 7mm, 300winmag) they have both been more accurate than the Part. The Accubond is a little more like the Partition in that it sheds a bit more weight in the frontal area on impact. The Interbond holds together better and retains a little more weight. In my opinion they are both better then the Partition. My personal favorite is the Interbond. I've had passthrough-bang flops on all the mulies I've shot with the 150gr 30cals out of the 06 and the 300mag. They work great for elk too! Brett
