It would kill many people in that town, over the space of several months or years - it would therefore be very "deadly." You could also have a poison with an extremely low LD50, which would also be "deadly." You're using the same word to refer to two different things. English is a bad language.
Like I said, the more precise term is probably *lethal.* The *lethality* of something. Being shot with a .223 is a lot more *lethal* than a .22.
I don't think ammo control is a serious possibility here, but if you were going to control one type of ammo you would want to do it for all types. Probably only small pellets and BB's would be the sort of thing that wouldn't need controls for.
Basically. But 9mm has about 3 times the energy as .22, so penetration would be more likely. There are supposedly reports of .22 bouncing off of the target's forehead - likely a factor of barrel length and distance from shooter to target.
Someone spraying a room with .22 will still be deadly. But it would be less deadly (or lethal?) than someone spraying the room with 9mm, or emptying a shotgun loaded with buckshot into it.
