I believe that is why historically the 125 Grain 357 magnum at 1350-1450 FPS and the 115 grain 9mm +P+ at the same velocity seem to defy logic as they perform poorly in gelatine, but work wonderfully on the street.
Everything I've seen shows that they perform well in gelatin (see www.brassfetcher.com). Depending on the round and it's construction they meet law enforcement standards of 12-14" of penetration with expansion. They don't "defy logic" the rounds were built to do what they do and they do it. There is also some hype about how well they performed "on the street" but that's another discussion and they have a record that matches well with other rounds of their class.
