RE: Accubond
The Accubond combines the accuracy and ballistic coefficient of the Nosler Ballistic Tip bullet with a bonded core for maximizing penetration.
The Accubond is a premium bullet, and I agree with you, it is not necessary for deer-size game. But it does let you use smaller caliber rifles for larger animals, like caribou, elk & moose. But of course, so do other premiums like the Barnes "X" series and the Trophy Bonded or the Partition Jackettypes.
