Rate of Fire (redirected from Rounds per minute)

Rate of Fire 

the ability of a given weapon to fire a specific number of shots per unit of time (usually one minute).

A distinction is made between the maximum and effective rate of fire. The maximum rate of fire of an automatic weapon (the cycle rate) is defined as the maximum number of shots per unit of time that the mechanism of a given model of a weapon permits. The effective rate of fire is defined as the number of aimed shots that is practically possible per unit of time from a particular weapon when taking into account the time for loading, aiming, changing settings, and so on. The effective rate of fire depends on the maximum rate of fire, the level of training of the rifleman or squad, the degree of automation of loading, and other factors. In view of this, the effective rate is always lower than the maximum rate. The desire to increase the effective rate of fire led to the introduction of automatic weapons.
