I used the Accubond bullet last year on antelope, deer & elk. The wife had a 160-grain accubond loaded up in her 7mm Ultra Mag. I had the 140-grain Nosler Partition in my 7mm-STW. We compared the entry & exit wounds of both bullets head to head on antelope & deer. I could not tell the two apart. We killed a total of four antelope & four deer. Two antelope & two deer were shot with accubond bullets & had exit wounds that matched te exit wounds of the partitions.
I killed a raghorn 5x5 bull elk with my 300-win mag & a 200-grain accubond. The accubond preformed perfect on the elk. I can not say that the accubond bullet preforms any better than the Partition.
I have used the partition bullet for years & will continue to do so in the future, after I run out of accubonds.
