The initial testing was done in 2008 and tested the velocity of 13 common handgun cartridges as it related to firearm barrel length. In 2009 an additional three calibers were tested and in 2010 and 2011 more calibers were added. Also in 2011 testing was carried out to study the "cylinder gap effect" on the velocity of ammunition shot from ...
In some instances, the powder may not have even been fully burned in guns with short barrels. So, the muzzle velocity of a 2-inch (51 mm) barrel is less than that of a 4-inch (100 mm) barrel, which is less than that of a 6-inch (150 mm) barrel. Large naval guns will have high length-to-diameter ratios, ranging between 38:1 to 50:1. This length ...
Limited production runs of Glock 19 and Glock 17 conversion barrel kits allowed these pistols to be converted to fire .22 TCM by replacing the barrel and recoil spring (rated at 11 lbs). This led to the development of the .22 TCM-9R variant, which uses a shorter bullet and overall cartridge length compatible with Glock and other magazines ...
The cartridge's 50-grain .22-caliber bullets have a muzzle speed upward of 4,300 ft/s (4,250 according to some [8]), and the cartridge is known for its long-range accuracy and velocity. [2] Its high intensity is notoriously hard on barrels, which require constant cleaning.
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.
A powder with a slower burning rate is used to make the most use of the length of a rifle barrel. Most .22 long rifle powders increase velocity up to about 19 in (480 mm) of the barrel. The powder used in the Stinger increases velocity up to the longest .22 barrel length tested by the NRA, 26 in (660 mm). [23]
The length of the barrel (especially for larger guns) is often quoted in multiples of the caliber, used, for example, in US naval rifles 3 in (76 mm) or larger. [2] The effective length of the barrel (from breech to muzzle) is divided by the barrel diameter to give a dimensionless quantity.
