I am a fan of Nosler ABs and Partitions and would probably pick whichever one shot the best groups between the 130 grain AB AND 140 Grain Partition. For reasons that escape me, the 125 grain .264" Partition is a bullet that I have never had much success getting to shoot good groups. OTOH, every other .264" Nosler AB, BT, and Partition has been as capable as the rifle and shooter would allow.
