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. External ballistics - Wikipedia

   en.wikipedia.org/wiki/External_ballistics

   Another attempt at building a ballistic calculator is the model presented in 1980 by Dr. Arthur J. Pejsa. [18] Dr. Pejsa claims on his website that his method was consistently capable of predicting (supersonic) rifle bullet trajectories within 2.5 mm (0.1 in) and bullet velocities within 0.3 m/s (1 ft/s) out to 914 m (1,000 yd) in theory. [19]

4. 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 ...

5. 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.

6. 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.

7. Ballistic coefficient - Wikipedia

   en.wikipedia.org/wiki/Ballistic_coefficient

   Very-low-drag bullets with C b ≥ 1.10 lb/in 2 (over 773 kg/m 2) can be designed and produced on CNC precision lathes out of mono-metal rods, but they often have to be fired from custom made full bore rifles with special barrels. [68] Ammunition makers often offer several bullet weights and types for a given cartridge.

8. .408 Cheyenne Tactical - Wikipedia

   en.wikipedia.org/wiki/.408_Cheyenne_Tactical

   The .408 Cheyenne Tactical (designated 408 Chey Tac (10.36×77mm) by the C.I.P.) [ 3 ] is a specialized rimless, bottlenecked, centerfire cartridge for military long-range sniper rifles that was developed by Dr. John D. Taylor and machinist William O. Wordman. The round was designed with a possible military need for a cartridge for anti ...

9. 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 ...
