Abstract
A high strength polymer-based cartridge casing can include a first end having a mouth and a neck extending away from the mouth. Next, a shoulder extends below the neck and away from the first end. The cartridge can have a frangible portion capable of being split upon discharge of a projectile. A projectile can be disposed in the mouth and a relief can be disposed on the neck near the mouth and projectile. The relief can form a gap between the neck and the projectile to receive an adhesive.
Claims4
A high strength polymer-based cartridge casing inclosing a volume, comprising:
- a first end having a mouth;
- a neck extending away from the mouth;
- a shoulder extending below the neck and away from the first end;
- a bullet configured to impact a target and disposed in the mouth;
- and
- a relief formed in the neck proximate to the mouth forming a gap between the neck and the bullet;
- and
- an adhesive disposed in the gap and in contact with the bullet,
- wherein at least the mouth, the neck, the shoulder and the relief are formed of at least one polymer.
A method of making a high strength polymer-based cartridge casing comprising the steps of:
- molding a component using a polymer, comprising:
- a first end having a mouth;
- and
- a second end opposite the first end;
- molding a neck extending away from the mouth, using a polymer;
- molding a shoulder extending below the neck and away from the first end, using a polymer;
- forming a relief on the neck, further forming a gap between the neck and a bullet configured to impact a target and disposed in the mouth;
- and
- applying an adhesive in the gap between the neck and the bullet and the adhesive contacts the bullet.
