124gr Hornady XTP, Federal HST or Speer Gold Dots will do you well from a 9mm. I've finished several car hit deer with my 9mm and Hornady XTPs. One of my uncle's was climbing down from a stand years ago and had 3 does come in on him @ less than 10 yards. He proceeded to shoot one of them with a 9mm, unknow bullets, she bled pretty good for a short distance but never recovered her. I killed her 2 weeks later when she came limping out into a green field. He hit the shoulder but it failed to penetrate. I want a 10mm just for this purpose.
