The CCI Minimag would be a good choice....or any other high velosity hollowpoint bullets.
I would NOT use any of the hyper velosity rounds (Velociter, Yellow jackets, or Stingers) as these rounds are designed to expand rapidly and can fail to penetrate enough on larger game.
I have.....errrr....heard rumors....that the .22 LR is very effective against whitetails with both head and body shots, but the hyper-velosity rounds are asking for trouble.
Be prepared for the deer to run a ways with a body shot and NOT leave much of a blood trail. It will die just fine but unless you are an excellent tracker or use dogs to help with recovery don't try it.......ahhhh, so I've heard anyway!
