[QUOTE="Doom2, post: 2646135, member: 108323"] The bullet and tip take time to heat up which is what Hornady claims to have found It was a long range phenomena. It is the air that approaches the stagnation temperature not the bullet. The air has to transfer the heat to the the bullet. It takes time and it also depends on how close the shock wave is to the nose. The bullet itself would take a lot longer to see appreciable heating. As for the bullet or air igniting the paper, there is very little total air being brought to to that temperature. As for understanding all of this it can be difficult. After World War II there was a tremendous amount of research into trying to understand how objects behave as they approach sonic velocity (Mach 1) and beyond. This included the behaivor of shock waves, aerodynamic heating, and their effect on aircraft and missile design. Truly understanding all of this falls into the realm of aeronautical and aerospace engineering. [/QUOTE]
