Patent number: 8424233Abstract: Clips for use with projectiles and projectile stacking systems in which individual projectiles are clipped together to form a stack are disclosed. The projectiles may be joined individually by a user before loading in a barrel, or during a loading process assisted by features on the breech of the barrel. The tail of each projectile includes a set of clips which engage the nose of a trailing projectile in the stack. Projectiles may be withdrawn from barrel and unclipped as required by the user.Type: GrantFiled: July 25, 2008Date of Patent: April 23, 2013Assignee: Metal Storm LimitedInventors: Joseph F. Cronin, Sean P. O'Dwyer, Roger H. Thompson

Publication number: 20130047880Abstract: A projectile for use in a barrel with stacked projectiles, particularly for a weapon which can be reloaded by a user in the field. The projectile comprises a tail assembly. The tail assembly comprises a casing and a closure in the tail assembly, the casing and closure forming a chamber containing a propellant charge, an exit from the casing for release of propellant gases into the barrel when the propellant is ignited to launch the projectile from the barrel, the closure closing the exit, wherein the closure is opened by ignition of the propellant within the chamber, a primer in a leading end of the casing, an inductor around the casing, and a signal detector at a leading end of the casing and inductor, wherein the signal detector triggers the primer and the signal detector receives a signal output from the inductor to trigger the primer.Type: ApplicationFiled: April 16, 2012Publication date: February 28, 2013Applicant: Metal Storm LimitedInventor: Sean P.

Publication number: 20110277657Abstract: A projectile for use in a barrel with stacked projectiles, particularly for a weapon which can be reloaded by a user in the field. The projectile includes a chamber containing a propellant charge, with an exit from the chamber for release of propulsion gases into the barrel. A seal blocks the exit and is opened by ignition of the propellant within the chamber but is resistant to gases produced by ignition of propellant in other projectiles in the barrel. The exit and seal are provided in a range of different forms. The exit may be an aperture in a wall of the chamber with the seal as a moveable barrier, such as a valve-like structure, for example. The seal may also include a rupturable or deformable barrier across the aperture. Alternatively the seal is a thin barrier around the charge such as a wax coating and the exit involves a disintegrable character of the barrier. The seal may also be an inherent property of the geometry of the chamber.Type: ApplicationFiled: July 25, 2011Publication date: November 17, 2011Applicant: Metal Storm LimitedInventor: Sean P.
