In the Partion the original idea was simply to keep the core from evaporating away from the jacket. A partition was added between the front and back of the bullet to keep the bullet core and jacket together. The lead in front of the pattion might be lost lost , but the core would stay in tact. On average Partitions will retain 60% of its original weight.

The next improvement in bullet design "Bonded bullets", think Swift A-frame here, allowed the front portion of lead to be welded to the jacket to increase weight retention even further. The only problem with most of these bullets was that they were made in a semi spitzer style with flat bases that had poor ballistic capabilties. For example the metal on the tip of the bullet could easily be dented in the magazine during recoil.

Fortunately, this problem had already been solved elsewhere with the ballistic tip bullets. These were being made with pollycarbonate tips and a boat shape tailed bullet. Nosler had its own called the "Ballistic Tip"

By now you should see where this going..

The "Accubond" is a nosler Partition, with a Bonded core, Ballistic Tip point in a boat tailed design.....

"Accubond's" provide the superior accuracy and flatter trajectory of the ballistic tips with reliable expansion and structural integrety of bonded core bullets.
