Do Bullets Fly Straight?
This video explains that bullets do not fly straight due to gravity and other factors. It details how bullet trajectory is an arc, not a laser beam, and how zeroing a firearm accounts for this arc and the offset between the optic and the bore. The discussion also covers factors contributing to 'flat shooting' cartridges, such as design, ballistic coefficient, and projectile length, and introduces the concept of spin drift.
