Rounds like the speer gold dot and the corbon DPX are above what any .38 special can do but doesn't reach the .357 magnum's potential, which is the point of the "magnum" ad the end of it anyway. You can get 600 Lbs out of a 4 inch full power 357 magnum revolver, but it won't be practical for most I would imagine. I'm guessing this would be where the mid level rounds would make sense. But do they really have enough of a power advantage over a 38 special +p to be worthwhile? I heard about these rounds from this article: http://hipowersandhandguns.com/can_less_be_more.htm If anyone's interested in where I'm coming from with this question. Thanks.
