yell95,
I do not have any experience with the .357 handirifle (wish I did!) But I do have a bit of experience hunting whitetails with the .357. I own a .357 lever action and I have killed 7 deer with it. all but one were 1 shot kills, and that one was my fault because I misjudged the distance and hit him too low in the chest. He ran off and i waited about 1 1/2 -2 hours before blood trailing him. he had run off about 150 yards and lay down in a brush pile. He was trying to get up when I finished him off with a shot to the neck. If I would have waited another hour or so, I most likely would have found him dead, but I hunt on public land and I'm surprised no one found him before I did. I have also killed several coyotes, coon, possums, rabbits and such with this .357. For deer hunting I use the remington 180 gr softpoint load. IMHO, for the ranges you quoted, your .357 is more than adequate for the job, assuming bullet placement is correct. Load up, practice often, and enjoy deer hunting with your .357!
