Lethality of the 22 LR standard velocity round

i just checked the stats on the basic American Eagle stuff that i shoot. it's faster than the stuff the guy in the article was using, so i'm guessing it would have better results.

If it's supersonic it will most likely loose more energy and have very poor accuracy downrange. Reason is when the round goes transonic is becomes unstable and is very prone to wind shift and inaccuracy in general. I't better to start out subsonic with a heavier round that will hold it's energy downrange. Oddly enough pellet gun shooters are much more aware of this and tune their equipment to be just subsonic.

pardon my ignorance, but what velocity is super sonic?
the federal stuff shoots 1240fps and the stuff the guy tested shoots 1050fps. is that amount of diffence going to yield vastly different results?

lemme guess:
altitude
temperature
barometric pressure
humidity
wind speed
the color of the trees
and i'm sure there's more i'm missing.
Speed of sound is primarily affected by air pressure and temperature. It gets slower with less pressure and temperature. At altitude it is much easier to break the sound barrier than it is at sea level.
If you wanted to tune a rifle to shoot standard velocity rounds under the sound barrier you would have to experiment with barrel length, max velocity is usually achieved at 16" and going either direction will slow it down.

Thats right, standard velocity RN penetrates differently then higher velocity HP rounds. Being subsonic it doesn't create shoke wave neither it expands, sort of just push tissue aside and swim through. I have witnessed deer killed with just that sort of round, not behind ears or anything but plain jane lung shot. Bullet went through rib cage, lung, heart and stopped somewhere in ribcage on the other side. Cavity was total mess - very simiral to broadhead kind of damage.
Headshots though I heard aren't very reliable for that very same reason - bullet does not create enough of hydraulic shoke, it has to be precisely placed to be effective.
I'd say all in all it may be lethal but why bother, there are effective tools for every job, 22lr is awesome where it is - training round.
Many man have fallen with a .22 as well. Not sure it it’s true or not, but I heard in US more people get killed in by than any other caliber…
In my phonebook test they didn’t penetrate any more than Fed. Champion 36gr plated ammo. Both expended (or more like got mangled) and neither went thru 1.8” book (out of a 4.5“ barrel), but the last page was town with the bullets still inside! Velocitors have a pretty large cavity so I’d guess a solid plated bullet would out penetrate either.

The backpack killer in Australia used a 10/22 in his crimes.
The police brought in all the 10/22s owned to see if they could identify who the killer was.
Oddly enough, the killer didn't turn his in(or it wasn't registered), eventually a victim who escaped lead police to him.
Thank god for registration & gun control

I was under the impression of 330 m/s @ std atmospheric.
I've used .22LR to slaughter coows sheep and hogs. One shot to the brain and it's all over. I wouldnt' want someone pointing a 22LR at me...
Too often, the .22 LR is thought-of as a toy...
