Thanks, those comments make me feel a little better with my choice. I still haven't zero'd in my gun with the Accubonds so if I can't get a really tight group with them I might try another bullet.
Here's the exact quote from American Hunter on the Accubond. First they complimented it but they finished with:
I often hear that its terminal ballistics are the same as the Partition, but that's not my experience. Yes, it is designed to lose weight as it penetrates, and the final weight retention will be similar to the Partition at about 60 - 70 percent. But I think how this happens in the game is different. Part of that weight loss is designed to keep the frontal area smaller than other bonded-core bullets so it will penetrate deeper. I like this bullet for game up to 500 pounds, but for anything bigger I'll stick with the Partition.
