I took 130g Ballistic Tips and 130g Accubonds. Loaded both with 4831
The Accubonds shot poorly. Four shots into a 3 inch stringing group.
The Ballistic Tips shot superbly. Four shots into a nice 1/2 inch clover leaf. Two of them into one hole.
Why such a dramatic difference?
Load for each was:56g IMR 4831 3.330 COAL
First guess is the length difference between the two and the difference to the lands.
I just found a great load for my 7-08 with 140 BT's, and exchanged the BT's for Accubonds, adjusted the seater to be in the lands the same amount, and was rewarded with identical POI at 500 and a 2 1/2" group.
