skull.. He said, even a high velocity, 22LR cannot penetrate a human skull. Shot an empty portable propane tank made up of steel @ 100 yards using cci minimag 36gr HP 1260FPS. So i did a test and. Honestly i didnt think it would go through it being a HP vs Round nose, but I knew for sure it would penetrate a human skull even before this test.
Prior to this debate, the same person said the same thing about a 17HMR @ 100 yards. I laughed so brought up the 22LR instead.
