Propellant Charging

Home > Small Arms Ammunition > Centerfire Ammunition > Propellant Charging

As with rimfire ammunition, centerfire charging methods depend on the machinery used. More high-speed continuous loading machines are used, forcing the adoption of sophisticated propellant meters. The sliding powder measure is capable of handling faster production rates. Lower-volume cartridge production is still performed on slower interrupted sequence machines.

Most centerfire loading operations include inspection immediately after the charging station. A pin will drop into the case, determining if the volume of propellant is out of specification. Electronic or mechanical sensors read the position of the pin.
