Subsonic cartridge for gas-operated automatic and semiautomatic weapons
First Claim
1. A cartridge loaded in a gas-operated weapon selected from the group consisting of gas operated automatic and semiautomatic weapons, the cartridge comprising:
- a cartridge case having a tubular shape with an open end, and oppositely disposed head, and a bore therebetween, the head having a primer cavity, a web separating the primer cavity from the bore, and a flash hole through the web;
a primer stored within said primer cavity;
a projectile disposed within the bore so as to close the open end of the cartridge case, the projectile having a weight of about 100 grains or more;
a charge cavity delimited within the bore between the web and the projectile; and
a propellant charge contained within the charge cavity in an amount sufficient to propel the projectile from the cartridge case at a subsonic speed and to recycle the weapon.

Abstract
A subsonic cartridge that enables a conventional automatic or semiautomatic weapon to fire a projectile at a subsonic velocity and cycle the weapon to eject the spent cartridge case, without the sonic report characteristic of supersonic projectile velocities. The cartridge includes a case having a tubular shape with an open end oppositely disposed head, and a bore therebetween. The head of the case includes a primer cavity, a web separating the primer cavity from the bore, and a flash hole through the web. A primer is stored within the primer cavity, and projectile is disposed within the bore so as to close the open end of the cartridge case. A charge cavity is delimited within the bore between the web and the projectile. The charge cavity is sized and shaped to contain a limited amount of propellant charge that propels the projectile from the cartridge case at a subsonic speed.

18. A .223 caliber cartridge loaded in a recycling weapon having a gas-operated reciprocating bolt, the cartridge comprising:
-
a cartridge case having a tubular shape with an open end, an oppositely disposed head, and a bore therebetween, the head having a primer cavity, a web separating the primer cavity from the bore, and a flash hole through the web;
a primer stored within the primer cavity;
a projectile disposed within the bore so as to close the open end of the cartridge case, the projectile having a weight of about 130 grains;
a charge cavity delimited within the bore between the web and the projectile; and
about 14 grains of propellant charge that completely fills the charge cavity, the propellant charge within the charge cavity being an amount sufficient to propel the projectile from the cartridge case at a subsonic speed and to recycle the reciprocating bolt of the weapon. - View Dependent Claims (19, 20)

21. A process of firing a cartridge from a gas-operated automatic or semiautomatic weapon, the process comprising the steps of:
providing a cartridge comprising;
a cartridge case having a tubular shape with an open end, an oppositely disposed head, and a bore therebewteen, the head having a primer cavity, a web separating the primer cavity from the bore, and a flash hole through the web;
a primer stored within the primer cavity;
a projectile disposed within the bore so as to close the open end of the cartridge case;
a charge cavity delimited within the bore between the web and the projectile; and
a propellant charge contained within the charge cavity in an amount sufficient to propel the projectile from the cartridge case at a subsonic speed;
loading the cartridge in a gas-operated weapon chosen from the group consisting of automatic and semiautomatic weapons having a reciprocating bolt; and
thenfiring the weapon by igniting the propellant charge, the propellant charge producing a chamber pressure sufficient to propel the projectile from the cartridge case at a subsonic speed and to recycle the reciprocating bolt of the weapon. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32)
