2. Transitional ballistics - Wikipedia

   en.wikipedia.org/wiki/Transitional_ballistics

   Transitional ballistics is a complex field that involves a number of variables that are not fully understood; therefore, it is not an exact science. [6] When the bullet reaches the muzzle of the barrel, the escaping gases are still, in many cases, at hundreds of atmospheres of pressure. [3] Once the bullet exits the barrel, breaking the seal ...

3. Taylor knock-out factor - Wikipedia

   en.wikipedia.org/wiki/Taylor_knock-out_factor

   The Taylor knock-out factor, also called Taylor KO factor or TKOF, is a formulaic mathematical approach for evaluating the stopping power of hunting cartridges, developed by John "Pondoro" Taylor in the middle of the 20th century. Taylor, an elephant hunter and author who wrote two books about rifles and cartridges for African hunting, devised ...

4. Terminal ballistics - Wikipedia

   en.wikipedia.org/wiki/Terminal_ballistics

   Terminal ballistics. Bullet parts: 1 metal jacket, 2 lead core, 3 steel penetrator. Terminal ballistics is a sub-field of ballistics concerned with the behavior and effects of a projectile when it hits and transfers its energy to a target. Bullet design (as well as the velocity of impact) largely determines the effectiveness of penetration.

5. Internal ballistics - Wikipedia

   en.wikipedia.org/wiki/Internal_ballistics

   Internal ballistics (also interior ballistics), a subfield of ballistics, is the study of the propulsion of a projectile. In guns, internal ballistics covers the time from the propellant 's ignition until the projectile exits the gun barrel. [1] The study of internal ballistics is important to designers and users of firearms of all types, from ...

6. Ballistic coefficient - Wikipedia

   en.wikipedia.org/wiki/Ballistic_coefficient

   In ballistics, the ballistic coefficient (BC, Cb) of a body is a measure of its ability to overcome air resistance in flight. [ 1 ] It is inversely proportional to the negative acceleration: a high number indicates a low negative acceleration—the drag on the body is small in proportion to its mass.

7. Ballistics - Wikipedia

   en.wikipedia.org/wiki/Ballistics

   Ballistics is the field of mechanics concerned with the launching, flight behaviour and impact effects of projectiles, especially ranged weapon munitions such as bullets, unguided bombs, rockets or the like; the science or art of designing and accelerating projectiles so as to achieve a desired performance.

8. Power factor (shooting sports) - Wikipedia

   en.wikipedia.org/wiki/Power_factor_(shooting_sports)

   Power factor (shooting sports) A high-speed photograph of a .38 Special bullet fired out of a Smith & Wesson Model 686 revolver. Power factor (PF) in practical shooting competitions refers to a ranking system used to reward cartridges with more recoil. Power factor is a measure of the momentum of the bullet (scaled product of the bullet's mass ...

9. Full metal jacket (ammunition) - Wikipedia

   en.wikipedia.org/wiki/Full_metal_jacket_(ammunition)

   Full metal jacket (ammunition) These .30-caliber (7.62 mm) full metal jacket bullets show the typical jacket openings exposing the lead alloy core on the base of the bullet to illustrate that a full metal jacket may not completely enclose the core. A full metal jacket (FMJ) bullet is a small-arms projectile consisting of a soft core (often lead ...
