Apples and Oranges
Quoting from NRA's American Rifleman from their May, 2004 issue:
"While other bulletmakers tout 90 percent weight retention from their bonded bullets, Nosler took a different approach. Its goal is deeper penetration, even at the sacrifice of weight retention. The problem with bonded bullets that are designed for high weight retention is that they quickly form a large frontal area that impedes penetration. Nosler designed its bullet to have about 60 to 70 percent weight retention. That obviously means that it will lose some weight. That's because it's designed to shed some of the expanded bullet material to keep the frontal area of the Accubond bullet a little smaller than some other bonded bullets. Accubond is designed for early expansion, but rather than tear completely apart as a Ballistic Tip often will, the Accubond's petals are designed to fold back tighter against the bullet shank. This makes a slightly smaller diameter mushroom to allow deeper penetration."
The Interbond on the other hand is made like the Trophy Bonded Bear Claw, Swift A-Frame and Scirrocco where the lead stays with the bullet and just mushrooms out. This has a greater weight retainage but impedes penetration.
The Accubond is supposed to be a replacement or substitution for the Partition and be more aerodynamic and more accurate.
