Range table
# Range table

A range table was a list of angles of elevation a particular artillery gun barrel needed to be set to, to strike a target at a particular distance with a projectile of a particular weight using a propellant cartridge of a particular weight. They were used for several centuries by field and naval gunners of all countries until gradually replaced by computerised fire-control systems beginning in World War II (1939–1945).

## Range table for US 3-inch (76.2 mm) field gun, models 1902-1905

This gun used a standard "fixed" cartridge with 15 lb (6.8 kg) shell, hence a single set of tables applied to all its ammunition.

## Range table for British 3 inch (76.2 mm) Stokes Mortar, 1917

Different propellant charges were used to achieve required range, angle of descent and flight time. This is typical of mortars and howitzers.
