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 ...
Ballistic performance. Bullet mass/type. Velocity. Energy. 3,600 gr (233 g) 2,200 ft/s (670 m/s) 38,685 ft⋅lbf (52,450 J) The .950 JDJ (24.1×70mm) is a powerful large caliber rifle cartridge developed by American gunsmith and weapon designer J. D. Jones of SSK Industries.

Common rifle cartridges, from the largest .50 BMG to the smallest .22 Long Rifle with a $1 United States dollar bill in the background as a reference point. This is a table of selected pistol / submachine gun and rifle / machine gun cartridges by common name. Data values are the highest found for ...
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 ...
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.
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.
The Whisper family of firearm cartridges is a group of wildcat cartridges developed in the early 1990s by J.D. Jones at SSK Industries. The Whisper family was developed as a line of accurate, multi-purpose cartridges using relatively heavy rifle bullets for a given caliber in subsonic loads. [1][2][3] The intention was to create an extremely ...
The 7.92×33mm Kurz [6][7][8][9] was referred to as the Pistolenpatrone M43 (pistol cartridge model 1943) or Pistolen-Munition M43 (pistol ammunition model 1943). This was part of the same duplicity under which the StG44 was originally designated as a "machine pistol" to disguise the true nature of the weapon from Hitler.
