The .308 Winchester has a 3.64 mL (56 gr H 2 O) cartridge case capacity. [9] The exterior shape of the case was designed to promote reliable case feeding and extraction in bolt-action rifles and machine guns alike, under extreme conditions. .308 Winchester maximum C.I.P. cartridge dimensions. All dimensions in millimeters (mm) and inches.
The .308 Marlin Express is a cartridge developed in 2007 by Marlin Firearms and Hornady. It is based on the .307 Winchester with a goal to duplicate .308 Winchester performance. The cartridge uses a slightly shorter, semi-rimmed case similar to that of the .220 Swift to function in lever-action rifles.
The effective length of the barrel (from breech to muzzle) is divided by the barrel diameter to give a dimensionless quantity. [2]: 81 For example, the main guns of the Iowa-class battleships can be referred to as 16"/50 caliber. They are 16 inches in diameter and the barrel is 800 inches long (16 × 50 = 800).
It is widely accepted within interdisciplinary circles that for a standard rifle firing full-powered cartridges (e.g. .308 Winchester), "long range" means the target is more than 600 m (660 yd) away, [citation needed], while "extreme long range" is generally accepted as when the target distance is more than 1,000 m (1,100 yd) away from the shooter.
Test barrel length: 26" Source(s): Accurate Powder [ 2 ] The 7mm Shooting Times Westerner , sometimes referred to as the 7mm STW , began as a wildcat rifle cartridge developed by Layne Simpson, Field Editor of Shooting Times, in 1979. [ 3 ]
Ballistics by the Inch (often called BBTI) was a project to test the performance characteristics of a variety of common handgun calibers/cartridges. The initial testing was done in 2008 and tested the velocity of 13 common handgun cartridges as it related to firearm barrel length.
Muzzle energy is dependent upon the factors previously listed, and velocity is highly variable depending upon the length of the barrel a projectile is fired from. [2] Also the muzzle energy is only an upper limit for how much energy is transmitted to the target, and the effects of a ballistic trauma depend on several other factors as well ...
