  • Reduced-energy cartridge with exterior sealing member for fluted chamber
    Patent number: 11656063
    Abstract: A reduced-energy cartridge for a chamber of a firearm includes a case and a sabot. The sabot is moveably attached to the case and supported for movement relative to the case from an unfired position to a fired position resulting from combustion within the combustion chamber. The cartridge further includes a sealing member that projects radially outward from the longitudinal axis and from the sabot. The sealing member defines a blowback boundary where the cartridge is configured to seal against an inner surface of the chamber of the firearm. A forward area of the cartridge and a rear area of the cartridge are separated by the blowback boundary. The sealing member is configured for releasably sealing against the inner surface of the chamber to regulate pressure at the forward area resulting from combustion within the combustion chamber.
