What does put the bullet to sleep mean?
This is a term adopted by some clever ballisticians to refer to a bullet that is flying through the air perfectly stable, no yaw, pitch, or oscillation. Most bullets fly in a cork screw path while oscillating around their axis. This is bad and very evil! Not only does this cause problems with sighting at different ranges, but it has been found through extensive tests, that a bullet that is put to sleep has as much as 40% less wind drift. WOW that is incredible! If you are able to achieve that level of stability, you are on top of the game and handicapped in no way. If you watch a top spin, it will mimic what a bullet does in flight, and if you can get it to spin perfectly stable so it looks as though it isnt moving at all, it will spin far longer than if it wobbles and or oscillates. That is what is meant by putting a rotating body to sleep.
