My experience on deer with a .357 is limited, but I would recommend the XTP in the heavier weights (158 grain and up) I have used this bullet in a .357 for several deer, and the .44 / .45 version for a lot more, at it just plain works. As in any handgun hunting situation, pick your shots, and try to avoid extreme angling shots, especially thru bone. Some will tell you that a 158 grain bullet at 1300 fps will bounce off a deers rib, but that's not true. Just be aware as a bullet expands, penetration decreases. I like full caliber hard cast bullets because they penetrate deep and cut a clean hole, leave a good blood trail, but that's in 44 / 45. I don't know if a hard cast in .357 is going to have the same, immediate effect as a larger bore, that's why I like the expansion from a soft point in that caliber.
As stated elsewhere in this post, 296 and 110 are basically identical powders, and are great full power powders for top velocity in magnum loads. They are not suitable for use in reduced velocity, practice loads. To get the best out of the .357, you need two powders - One like 296 for max hunting loads, and another for loading mid-range and plinking loads. Faster burning powders like Unique fit well in this role.
