I just viewed a video of an SR-71 Blackbird spy plane. It stated the plane flew at 2,200 mph (Mach 3) and the surface temperature reached 1,000 degrees due to friction.
Has anyone ever determined the temperature of a high-velocity bullet when it reaches it's maximum speed? Years ago I remember reading that a .270 bullet rotates 180,000 rpm at it's maximum.
When you think of all the physical forces exerted on a fired bullet, it's amazing they can be so accurate and effective.
