I posted this on another forum a while back. I came across this steel block while I was cleaning out, and organizing my gun room a while ago. The large hole that almost made it thru the block was a .30 Cal. Carbide Core AP bullet pulled from a .30-06 and handloaded in my .300 Weatherby Magnum. You can see in the photo of the back of the block that it almost made it completly thru. The slug bounced back and was found about 15 feet in front of the block. The shot was from about 50 yards. You can see in the photo the copper jacket was almost completly shed, but the Carbide Core remained intact. The large craters were made by M-193 Ball Ammo in 5.56 NATO fired from a AR-15. The very small dimples that are barely visible were full house 240 Gr. .44 Magnum JSP rounds fired from my Ruger Super Redhawk. The material was 4140 Pre Hard. About 38 to 40 Rockwell C. billt
I've done stuff like that too Billt. A friend gave me some 7/16" thick steel I-beam sections. 44 Mag just bounced off it. Regular 223 fmj would make a crater. SS109 would usually penetrate. I still have the lead core and steel insert from one of the rounds that made it through. It's a lot of fun trying different types of ammo on steel, wood, etc...
