Myself I would choose a 140 gr perhaps a Nosler Partition or similar constructed bullet, in the 7x57.

Whitetail are not that heavy a deer species and hogs too depending on how big and tough they are where you are. A 140 gr should still kill however and give a flatter trajectory. Otherwise something in 150 or 154 gr.

I would go for the 160 to 175 gr projectiles for larger species.
