223 muzzle velocity is something like 3k off the top of my head. I think. Eitherway, the point stands. Few people have muzzle velocities memorized so it's kind of a gay area to be pedantic about.
Also a Mauser C96 isn't most handguns. Let's take a 9mm glock 19 ~= 1100 FPS
Looking it up a 20" barrel, 55gain 223 muzzle velocity ~= 2979 FPS
I'd say 1100 is close enough to 1/3rd that of a 223 to make this meme perfectly acceptable.
.22 long rifle...................1,262
.22 magnum...................1,450
.357 magnum.................1,468
.40 S&W.........................1,262
I call bullshit.
It's not bullshit.
It's a close enough approximation to bathe a point. The tweet made the wrong point, but the premise is fine.
Btw, the 22 velocities you gave are rifle velocities
The .22s are from a pistol chart.
It's bullshit.
