[QUOTE="LouBoyd, post: 320515, member: 9253"] I'm of the opinion that the lead cores of high velocity jacketed bullets ARE liquid as they impact on a solid surface. When a bullet splatters some of it's energy remains as kinetic energy of the fragments but the core is heated too. I've watched .223 bullets impact on steel armor l plate though a Gen III night vision scope. They flash on impact which means the splattering core is hot enough to emit infrared energy in the 800 to 950 nanometer (0.8 to 0.95 micron) wavelength range. Significant emission at that wavelength requires a surface of at least 800 F which is hot enough to be molten. [/QUOTE]
