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.

Spotter ammunition projectiles adapted to be fired from a firearm, methods for making spotter ammunition projectiles, and spotter ammunition cartridges including spotter ammunition projectiles are provided. In one example, a spotter ammunition projectile includes a projectile body section extending in a distal direction to a body distal end portion. A projectile ogive is coupled to the body distal end portion and has an outer ogive surface that tapers in the distal direction towards a shoulder. The projectile ogive includes a post that is disposed adjacent to the shoulder and that extends therefrom in the distal direction. An ogive nose cap is disposed adjacent to the shoulder and covers the post. The post and the ogive nose cap are cooperatively configured to define a cavity therebetween. A pyrotechnic spotter composition is disposed in the cavity.
