The bore to barrel length ratio is called "caliber" in naval gunnery, [2]: 81 but is called "length" in army artillery. Before World War II, the US Navy used 5"/51 caliber (5" L/51) as surface-to-surface guns and 5"/25 caliber (5" L/25) as surface to air guns. By the end of World War II, the dual purpose 5-inch/38-caliber gun (5" L/38) was ...

The M4's 14.5" barrel length reduces muzzle velocity to about 2900 ft/s. [187] This reduced wounding ability is one reason that, despite the Army's transition to short-barrel M4s, the Marine Corps has decided to continue using the M16A4 with its 20″ barrel as the 5.56×45mm M855 is largely dependent upon high velocity to wound effectively.

The longer barrel results in significant reductions in felt recoil (due to increased weight) and muzzle blast, with higher velocities, especially if factory-loaded rifle ...
