I usually hand load, but have used a good deal of factory loads. About any decent hunting bullet from say 130 to 200 gr. out of a 30.06 Spr. will kill deer cleanly.
My preference is the Nosler Partition or Sierra Game King bullet. My 30.06 Spr. just happens to "like" a particular lot of Federal Premium that uses the 180 gr. Game King bullet.
However, be mindful that ammo is made in "lots". These lots change as a normal result of the manufacturing process. One lot might be rather different from another .... so if you run out of one lot and move to another, double check the groups just to be sure.
