I have taken Whitetail before with the 45 acp and as long aas you keep your shots to a reasonable distance, the load you are talking about should work just about as well as anything else.
I believe, as Larry the Cable Guys sez, I believe that if you place your shot properly most of the defensive loads for the 45 should work on Bambi. The load I used was a Hornady 230 gn soft nose over a full charge of Unique and it penetrated t&t at about 25m. Nowadays I prefer a 238 gn cast swc slug of Elmer Keith design for the 45 Auto Rim and keep it just a bit below 900'/sec. This year I hauled my 5" Springfield around with those loads in it but never got the chance to use it. I would keep most of my shots to the 25 yd mark, but that is just me and my failing old eyeballs, although I sight the darn thing at 50m, so go figure.........
Doug - the 460 is a hot one and should work well for you. Hey, btw, I found the hole, the one where I thought I missed (but didn't). I feel many betters now........
