I just started reloading for my brothers 270 wsm Accuracy is ok. I am getting 2 to 2 1/2" goups at 100 yards. The problem is 2 shots will be very close together then one flyer about 1 to 1 1/2 inches left or right. I have tried a couple of different powders, sp and btsp bullets, seating depth and powder charges. The rifle is a weatherby vanguard.
Is this the best I can expect or is there something else i can try?
