Since the Accubonds have came out I have not been able to test them at extended ranges but with the last Hot rod I built (A 7 STW with a 31' barrel) I was able to get 3800 ft/sec using a 140 grain bullet. Accuracy was ok, but best accuracy was just over 3750 ft/sec.
Anyway, at the time I had two different loads for it one load was for anything up to 500 yards and used a partition for its toughness and ability to hold together at those distances and velocities.
The other load used Ballistic tips in order to expand at extreme distances and velocities at the Point of impact. I am/was hoping the Accubonds would eliminate the need for two loads.
So far the Accubonds have performed well at the distances I have tried them but I have not exceeded 800 yards with them yet. (I hope to change that soon).
When I get the chance, I will try a shoulder shot first just in case (Per your experience with them).
That is what I had to do with the partitions at long distances to make them expand.
Thanks
