You mean .223 Remington. Big difference between that an a .22 LR (or short). https://lynxdefense.com/whats-the-difference-between-22lr-vs-223-5-56mm/
Well, the .223 is usually super sonic, while the .45 ACP is subsonic (like the .22LR) Which would you rather be assaulted with? A supersonic .223 Remington from an AR-15 or a subsonic .45 ACP from a Tommy gun? Both will kill you.
There's no such thing as an assault rifle period. A tank is an assault weapon. By the definition of anti-American Leftists, a derringer is an assault weapon. The Left is disgusting.
.22 LR is supersonic. I buy those little .22 short CB subsonics for plinking with my old Marlin. Very quiet.
Supersonic range is about 1100 fps yes? Isn't a standard .22LR about 1,000 fps? Although I guess you can have different hotness levels on the powder. K, a "cuspy" round, heh
