Another thing I have found is loads that shoot ballistic tips well shoot practically the same with Accubonds.
I totally agree with you. I have some loads that shoot exact powder and amount with 120 BT’s and 140 AB’s. IMR 4350 works well in mine.
I believe what Cajun is saying is that it's know than when you use the 140gr BT and the 140gr AB with the same exact load you get the exact same POI. These two bullets are know for that. So you can load both and use whichever one is best for the occasion.
