You don't need 24" of penetration on a human.
Unless they're standing sideways to you. Make sure they're facing you before you shoot.

I will. After the first couple of shots, I don't think there will be an issue. At home self defense distances, I could easily put 10 rounds into center of mass within a few seconds. Not many people will be able to take that and walk away. This is where the semi-auto rifle really comes into it's own. As long as it has dependable feeding and ejection, the old 10/22 is my choice. I don't really care whether or not it makes dime sized groupls at 50 yds. But I still do get 1" groups with mine if I try. I keep a 4x scope on mine for quickness and target acquisition at plinking distances.Unless they're standing sideways to you. Make sure they're facing you before you shoot.
B) .22 copper plated round nose at 1235 fps with a 40 grain bullet.
Pretend I'm the bad guy -- First thing I'm going to do is take out the shooter with the 22, and from a range where she can't do much damage by shooting at me.
The point being, someone "armed" with a 22 cal rifle is going to DRAW FIRE more than they're going to provide defensive cover.
First rule in armed defense: "Bring enough gun."
You are almost correct... here is the full equation E=1/2M X V(2)and energy is Mass X Speed "squared"
