I would be interested to hear more about your penetration tests on dead steers if you would not mind sharing it.
I think that is definitely true for hunting, and I am beginning to wonder if it may also be true for DG defense as well. In velcocity, energy and penetration they seem to be neck and neck. It looks like from all the data I can find and from all the comments here, the 460 and the 500 are about equal in everything except the slight advantage to the 500 in crush cavity volume due to larger diameter bullets. The only thing that could tilt decidely in favor of the 500 is if the big 700+gr bullets actually out penetrate the 400-500gr bullets in the 500 by a significant margin. Since the velocity and energy of the 700gr loads is only about 2/3's of the 400-500gr loads, I don't know if the penetration will even match the lighter loads, much less best it. I sure wish we had some penetration info on those big loads, because I have been surprised before when trying to guess penetration based on ballistics.
The only article I have where a 460 was used in defense on an Alaskan grizzly, the charging grizzly turned after the first shot at close range and was finished by 2 more shots. All three shots completely penetrated the bear. This was a 6'3" interior grizzly not a big coastal brown, but still the performance was impressive. Of course the next bear might keep coming. One incident does not establish what a round will consistently do in that situation, but plus one for a stop beats minus one, especially to the guy in the actual shooting.

Besides, from a ballistics standpoint the .500 and .460 are kind of like the .30-06 and the .308, as far as I can tell. There are differences, but for deer hunting purposes they seem small enough to be practically insignificant. So all other things being equal, the added flexibility of the .460 becomes kind of the deal breaker with me. Even if I end up loading my own and the ammo cost isn't an issue, I like having the additional options, I guess.
