Bullet spin is not at a constant rate, it does decay but just much slower compared to the decay of bullet velocity due to atmospheric drag.

Have you seen the videos of bullets being fired from a handgun into a frozen lake? Bullet spins like a top on top the ice. An exaggerated example but the properties are the same.

Maybe we should get the Slo Mo guys to video a bullet a 1000 yds and count the revolutions per foot of travel!
