...you seem to enjoy learning new facts about some of this stuff.

Here's one for ya, but I'll give you a chance to figure it out first for yourself.

You know that the rifling in a barrel imparts a spin to the bullet, which stabilizes the bullet like a gyroscope.

So...how FAST do bullets spin? Say, a bullet fired from an M16A1 like we used in the "Nam?

I'll give you a couple of hints:

1. the rifling in the barrel makes one complete revolution every 12 inches.

2. the muzzle velocity of the bullet is approx. 3100 feet per second.

See if you can figure it out!
