I have not used the accubonds yet. The X bullets aere great perfomers but as RR said they didn't shoot well in some rifles. The new TXS is supposed to cure that problem and I wouldn't give up on Barnes without trying them for accuracy. I have heard very little negative on the Accubonds but I have not had a reason to try that kind of bullet Most of my guns shot the X bullets pretty good but I have been a long time user of the Nosler Partition and have vever had season to doubt them.
