it is this kind of quote that i do not fully understand. it appears to be the mentality of so many forum posters about the killing power of the 22. it just sounds like you are just barely favoring the 22 over a bat.
i cannot help but think that maybe the shooter does not feel man enough that he is not handling a more powerfull weapon.
i am trying to understand where the additional penetration power would be needed in home defense situations, assuming the cci velocitor is already shredding the target.
CCI Velocitors are not going to SHREAD the target. It is going to puncture the target many times. I have read many many articles and had seen that same video you posted well before you found it, all in an attempt to comfort myself that my .22 could work for home defense as well as coyote control. It will do the job, but it is not going to drop a coyote in one or probably even two shots unless they are clean head shots. They are also not going to drop an intruder in one or two shots. Many police departments that used to use 9mm have dropped them for larger rounds because they were finding that perps were taking full magazines to center mass and surviving.
A velocitor is 40gr traveling about 1400 fps. A .223 which as I stated earlier is not intended to kill but mortally injure is a 55 to 70 gr traveling well over 3000 fps. The energy is entirely different, well more than double, and even that is not going to have immediate knock down power.
And as another stated, a 22 HP will not mushroom in a target because the velocity is to low.
So the long and the short:
In most cases just pulling the rifle or even firing a couple shots that never even land on the target will scare most intruders away.
In the unlikely event that you have a drugged up large massed intruder, you could unload all 25
rounds into center mass and have them continue their advance. They will likely die from their wounds, but they may manage to do you some damage in the mean time. When it comes to stopping power you cant beat a hollow point that is going to tear flesh apart and cause massive blood loss and organ damage.
Like I said, all I have is a .22 and I will use it if God forbid I need to, but no one here is going to blindly tell you that it is the ideal tool for the job.
And I am "man" enough to knowledge the difference.
