The guy behind the counter said he knew that it was the choice of assassins because it would bounce around in the head of the victim causing great damage.
It must be true because I saw it on one of the TV shows I watch and they were examining an old skull. They knew he had been killed by a 22 because of all the dimpling inside the skull from the bullet bouncing around. Same show where they pick up a spent bullet and immediately identify it as a military sniper rifle because it was a .308.
I use the same bullet for my .308 hunting rifle, my .308 M1 Garand, my 300 Wby and my brothers Ruger 30-06. I must be doing it all wrong. I am such a dummy.
