Home Forums Hunting & Shooting Handguns why do new handgun calibers so often fail?

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.
