Just listen to this dude.
If you can do this at those ranges im pretty sure you can penetrate a skull especially after multiple shots.
LOL. Gents, I've been a Police Officer for 21 years and a firearms trainer for 15. Now if all things are equal I suppose you'd have no problem staring down my 5.56 NATO. All things being equal! Which they aren't.
Answer me this quizzlings, if the .22lr is such a bad ass round why do no military units in the world use it as their main caliber? Why do no police departments use it for anything but killing varmints? Yes, the .22lr is everywhere. It is cheap and you can carry a lot. In a stressfull situation most normal people forget to take the safety off let alone remember shooting basics. If you have someone on the range every day with a specialized .22lr rifle then they might make those long shots on moving targets. MIGHT.You've got to see the big picture. Well, maybe you don't.
And I believe I've said, "Not everyone can make those shots." Some folks can hit center mass which is standard. If I can't end it then I want it dragging aits leg or picking itself up off the ground as I get my ass outta dodge or to a place I can better defend or give me time to get up closer and deal with it in a less dangerous manner.
The big picture isn't always what I can do based on years of training. It is what can those around me who don't have that training do.
Yeah, I think you're gonna need all those bullets. 22
