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.
A guide to the recoil from the cartridge, and an indicator of bullet penetration potential. The .30-06 Springfield (at 2.064 lbf-s) is considered the upper limit for tolerable recoil for inexperienced rifle shooters.

Barrel length helps determine a specific cartridge's muzzle velocity. A longer barrel typically yields a greater muzzle velocity, while a shorter barrel yields a lower one. The first AR-15 rifles used a barrel length of 20". In the case of the 223 Remington (M193), ammunition loses or gains about 25.7 ft/sec (7.8 m/s) for each inch of barrel ...

This new design was accepted, type classified and officially adopted as the United States Rifle, Caliber .30, Model 1903 and entered production in 1903. The ...
