Pharaoh2, you made some minor mistakes in your argument, but I get what you are trying to say. But, regardless of velocity, we need to choose cartridges that have a reasonable expectation of killing a game animal with a single shot, within the range limitations of the cartridge, from any angle. The .22 rimfire argument doesn't do it for me because there is not a reasonable expectation of a one shot kill on big game except when the little bullet can be placed with a surgeon's precision. While the .357 isn't quite as bad, it still fails to fulfill the requirement of the reasonable expectation of a one shot kill. Suggesting that an unsatisfactory bullet that hits is better than a good bullet that misses is not an argument. Anyone can make a poor shot with any firearm under a variety of conditions for an infinite number or reasons. A miss is a miss, and that's all it is. We used to laugh at the guys who would miss with a .30/30 and go buy a .338 thinking more power would fix the problem, but what I mean is, had the fellow with the 7-08 been armed with the rimfire instead, the deer would of still been wounded. Had he hit the vitals with the 7-08 the deer would be in the freezer, but not necessarily so with the .22.
I agree with what you say about large slow moving bullets, but a .357 is just slow, it's not large. As a result the bullet does not have enough momentum to penetrate as deeply as we would like. Jacketed bullets in this caliber range from OK to miserable. A heavy, hard cast, SWC has the jacketed bullets beat any way you look at it, because a cast bullet don't loose mass as it penetrates, and the flat nose disrupts more tissue than does the JHP that opens quickly (as it needs to in good guy vs bad guy shootings) and as a result penetration is shallow.
If the deer hunter chooses a .45/70, a .444, a 38-55, a .40-65, or a .30/30 loaded with cast bullets, there is a reasonable expectation that they will be able to kill their deer with a single shot from any angle within the range limitation of those cartridges. While it is legal to use marginal cartridges, I would advise those contemplating the use of .357's .25/20's, .32/20's, .30 Carbines, etc to reconsider. Despite the fact that these cartridges have killed deer in the past, that doesn't make them deer cartridges. They are excellent small game cartridges, but not deer cartridges.
