"Cop Killer" hand gun rounds

[cousinkix1953]

Cop killer rounds are any rounds that kill police officers. Period. Could be .22lr, could be a BB gun, could be 9mm. Sad that the term even exists, though.

TRUE; but these idiots haven't figured that out. You're dead if you get shot in the head with most any kind of bullet. How dare somebody like G Gordon Liddy or SJPD sergeat, Leroy Pyle point out the fallacy of such stupid laws.

You can kill somebody with properly placed pellet, from a Benjamin or Sheridan air rifle. Those things are as deadly as a .22 LR at close range...

No need to debunk this myth, dont waste that helmet unless you really want to try it for personal information. I used a PASGT helmet and shot it up with everything from .22 to .50CAL. I think the only stuff that didnt penetrate was the .25 AND .32 CAL rounds. This was done at various distances from 5 yards o 50 yards with a small collection of watermelons I wanted to get rid of. Everything was a thru and thru shot, nothing as far as I know didnt make it all the way thru. Helmets are designed for shrapnel and glancing blows from low power rounds, unfortunately, that didnt stop rounds from penetrating it on glancing blow as well.

I've heard various criticisms of the Box O Truth methods, but I do wonder as to why his tests showed such a variance from yours?

Also, I think to really accurately do this test, one would need quite a few helmets, as the structural integrity of each helmet is compromised each time it is shot. perhaps not completely, but it could be the difference between a bullet puncturing and not puncturing a helmet.
