I found sub MOA accuracy with both XTerminator and AA2015 with a slight advantage to AA2015. I went with the XTerminator to get the extra 150fps. My 6mmDTi really likes them with AA2015 powder as well and it runs them at 3600fps with my fireforming load. These bullets are not benchrest quality but if your gun likes them they should do fine although with their blunt shape they are not the best for longer range out past 300 yard or so. Thats why I decided to use all the ones I have (2 thousand) in the short barreled AR for now anyway. I killed quite a few coyotes with that bullet last year.
