Re: Nosler Accubond Performance
You are expecting the bullet to do what it was not designed to do; develop a large mushroom and keep that mushroom throughout the wound cavity.
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."
So a small exit wound is just like it was designed. It would be the same with a Nosler Partition which loses the front and the rear cylinder stays intact below the cross member in the bullet. If you want less penetration but a larger exit then you need the bullets that keep the large mushrooms like Scirroccos, A-Frame, Interbond, Northforks or a smaller wound channel but good penetrations with the monolithics like Barnes, GMX, E-Tips.
