Amazing how the lead seemed to liquefy and splash on impact with the hard targets. Even the airgun pellets seemed to do it in the second vid. The spiral trails left by the spinning bullets as they left the barrels was pretty cool too.
Not seems, it does liquify, including materials harder than lead. There's LOTS of heat in those impacts. Really high velocity the lead vaporizes. Try a soft point .220 Swift or similar at around 4,000 FPS on a nice hard rock (use some sense on how close and at what impact angle) and watch the pretty metallic deposition patterns.
Tank kinetic energy rounds with depleted uranium cores are pyrophoric and ignite after impact. So first the round blows a hole in your vehicle, thanks to the tungsten shell, and then sets everything on fire ...
If you find the right pictures from the various Arab-Israeli dustups in the 70's you could even tell which AFVs were hit with APFSDS (armor piercing fin-stabilized discarding-sabot) rounds because the FINS left impact marks as well.
