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
From a 270win
