  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. 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 ...

  4. External ballistics - Wikipedia

    en.wikipedia.org/wiki/External_ballistics

    External ballistics. This schlieren image of a bullet travelling in free-flight demonstrates the air-pressure dynamics surrounding the bullet. External ballistics or exterior ballistics is the part of ballistics that deals with the behavior of a projectile in flight. The projectile may be powered or un-powered, guided or unguided, spin or fin ...

  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. 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.

  7. 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.

  8. .277 Wolverine - Wikipedia

    en.wikipedia.org/wiki/.277_Wolverine

    The .277 Wolverine (6.8x39mm) is a wildcat cartridge. It is a multi-purpose mid-power cartridge with increased ballistic performance over the AR-15 's traditional .223 Remington (5.56×45mm NATO) cartridge. The use of a modified 5.56 case means that at minimum, only a new barrel is needed to convert any 5.56-based firearm to .277 Wolverine.

  9. Forensic firearm examination - Wikipedia

    en.wikipedia.org/wiki/Forensic_firearm_examination

    t. e. Forensic firearm examination is the forensic process of examining the characteristics of firearms or bullets left behind at a crime scene. Specialists in this field try to link bullets to weapons and weapons to individuals. They can raise and record obliterated serial numbers in an attempt to find the registered owner of a weapon and look ...
