The mitrailleuse's dependence on manual loading meant that its firing rate depended greatly on the skill of its operators. A skillfully manned Reffye mitrailleuse could sustain four volleys (100 rounds) per minute in ordinary operation and reach five volleys (125 rounds) per minute during emergencies. The rapidity of discharge of each individual volley (25 rounds) was controlled by the gunner's action on a small manual crank on the right side of the breech. The weapon's 25 barrels were not discharged all at once, but in rapid succession. Because it was so heavy (1,500 lbs), the Reffye mitrailleuse did not recoil during firing and thus did not need to be re-sighted on its target after each volley. This essential absence of recoil during firings was promoted by Reffye as a considerable advantage over conventional field artillery. Each regular battery of Reffye mitrailleuses lined up six guns firing together, more or less side by side.
