Well placed hits (aim to break the off-side shoulder) and heavy for caliber bullets of expanding (HP) design for deer, and wide flat nose design for piggies. If you want one bullet design for both, use the piggy loads. There are hotter, but Federal Premium Hunting 180s are easy to come by.
IF you are hunting from a stand, and willing to wait for the animal to present you with an archery-type broadside-to-quartering away angle, then a self defense style 125gr HP will be okay for deer.
You'll probably never NEED a gun. I hope you never do. But IF you do, you will need it worse than anything you've ever needed in your life.
IF we're not supposed to eat animals,
howcome God made 'em outta meat?
