It's the luck of the draw in whether your particular rifle is going to shoot any load well regardless if it's a handload or factory loaded. It depends on your budget but if I was going to use strictly factory ammo in the 300 WSM I would opt to get 3 different premium 180 grain loads such a partition, accubond or barnes Xand use the one that shoots best in YOUR rifle.The 180 gr willnot destroy as much meat asthe lighter 150 and 165 grain bullets in 300wsm. Just my $.02
