Shotgun cartridge integrity testing
When making small arms ammunition, such as shotgun cartridges, the shot pellets, wad and powder are contained in a plastic case. This plastic case is seated at the bottom into a brass alloy base and the contents are held in place within the case by either a rolled turnover (RTO) or a crimp closure. This closure acts as an intrinsic element in managing the pressure and velocity of the cartridge.
Testing the separation force of the base from the plastic case together with the seal strength of the RTO/crimp closure, provides a key indication of the quality of the cartridge.
