Actually the Accubond is not the same. Partition is as the name implies, 2 sections separated by copper ond no bonding of the lead to the jacket material. Separation is prevented physically by the lower lead in the base being mostly encased in the jacket behind the partition. The Accubond is like other bonded bullets, chemically bonded lead to the jacket to reduce separation. I think the Trophy Bonded Bear Claw is a partition that is also bonded.

As I've mentioned I've had separation issues with the Part. Don't get me wrong, I think the Partition is a great bullet. I just like the accuracy of the Accubond better and the fact the tips won't get deformed after loading and unloading or shooting the rifle (shells in magazine well). Now if they'd just make a Partition with a ballistic tip I think that would be a great improvement, maybe bond the nose section lead.
