[QUOTE="Howland, post: 1363984, member: 103509"] Is atmospheric drag really enough to melt lead? If this were so, all-lead bullets would melt before arrival on target. Plus, the ballistic coefficient would be unstable and continually degrade. Some might never even get there. I maybe wrong, but my instincts tell me that even a bullet sent from a superheated chamber at +/- 1,900 mph through -20°F is still going to arrive pretty darn cold. This may need a physics degree to solve, I don't know what the thermal coefficient of hardness is for lead. Does anyone have an ASTM manual? I'd just solve it with a follow-up shot. It takes much less time than a Bachelor of Science. [/QUOTE]
