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.
Well, that's good news, and I will defer to your infinitely wider experience in applying bullets to flesh than I. But on paper, the evidence points to 200-300 fps advantage to the 10mm. It's enough to give pause to us who are less experienced.
