Yeah, you're 1800fps is gonna be 800fps in you 2" gun.
It's better than a sharp stick, but if people are really serious about protecting themselves, they need to step up.
I chronied some rimfire ammunition thru my wife's 2" .22 WM revolver today and was a little surprised at the velocities.
Winchester Supreme 34 gr. @ 1359 fps
Winchester FMJ 40 gr @ 1163 fps
Remington Premier 34 gr @ 1154 fps
Winchester Super X HP @ 1066
The Remington Premier grouped quite a bit better than anything else shot today. Just bringing this back to top because there seems to be a little interest as of late with the .22 magnum ammunition.
