Not sure I agree on the 10mm. It significantly outperforms the .45acp and the 9mm when properly loaded. It did fall by the wayside for a while, but there are a lot more models currently offered, and it's easier now to find factory loads on the shelf. The odd thing is that most of those loads I'm seeing locally are still 10mm Lite.
I didn't find the 10mm to significantly out perform 45ACP +P.
Muzzle Velocity: 1400 fps is only 150 FPS faster. More, but not significantly more ... not so any animal hit with it would notice.
Clearly, "significant" has an arguable definition. We've all been down this road before. We can be in complete agreement though, and the market can still act as if we are not.
