  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. 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.

  6. 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.

  7. Ballistic coefficient - Wikipedia

    en.wikipedia.org/wiki/Ballistic_coefficient

    The test results were obtained from many shots, not just a single shot. The bullet was assigned 1.062 lb/in 2 (746.7 kg/m 2) for its BC number by the bullet's manufacturer, Lost River Ballistic Technologies, before it went out of business. Measurements on other bullets can give totally different results.

  8. .577/500 No. 2 Black Powder Express - Wikipedia

    en.wikipedia.org/wiki/.577/500_No._2_Black...

    The .577/500 No. 2 BPE was a popular cartridge in India for hunting all thin-skinned game up to tigers. [ 1 ] It did not face competition from comparable .450 rounds there in the decades following 1907 due to the ban on British military calibres. Like the .500 Black Powder Express, the .577/500 No. 2 BPE was never popular in Africa, not being ...

  9. 7.5 FK - Wikipedia

    en.wikipedia.org/wiki/7.5_FK

    The goal of the 7.5 FK project was to create a cartridge with a level of performance that could exceed that of the highly effective 125 gr (8.1 g) JHP .357 Magnum load, [clarification needed] be at least as effective terminally as the 7.62x39mm Russian and 5.56×45mm NATO cartridges when fired from short (8–10 in (20–25 cm)) barrel AK and ...
