Ballistics (from Greek βάλλειν ballein, "to throw") is the science of mechanics that deals with the launching, flight, behavior, and effects of projectiles, especially bullets, gravity bombs, rockets, or the like; the science or art of designing and accelerating projectiles so as to achieve a desired performance.
A ballistic body is a body with momentum which is free to move, subject to forces, such as the pressure of gases in a gun or a propulsive nozzle, by rifling in a barrel, by gravity, or by air drag.
A ballistic missile is a missile only guided during the relatively brief initial powered phase of flight, whose trajectory is subsequently governed by the laws of classical mechanics, in contrast (for example) to a cruise missile which is aerodynamically guided in powered flight.

    Simple Ballistics Question: Point of Impact with a Longer Barrel

    The following question has been bugging me for several days. 1) If you replace a barrel on a revolver with a longer one (e.g., Dan Wesson) the revolver will shoot lower. 2) If you put a longer barrel into a plasticy semi-auto (e.g., Glock), it will shoot higher. Why the different behavior...

    Sighting In / Ballistics App

    Can anyone recommend a user friendly ballistics calculator for iPhone? I am not experimenting with hand loads, or 1000 yard shots, and I am not a hunter. I just want something that will take common firearms, common factory ammo for plinking and give me bullet drop info in yards and inches, not...
