Abstract
A projectileless ammunition system (20; 320) includes a metallic case (22; 322). A propellant charge (26; 326) is carried by the case and covered by an over-powder member (24; 324) in the absence of a separate projectile. The ammunition is advantageously used with an industrial ballistic tool operating so that each spent case serves as the effective projectile to be propelled by firing of the next round of ammunition.
Claims12
A method for operating an industrial ballistic tool to discharge a plurality of ammunition rounds, each having a case and a charge of propellant comprising:
- (a) providing a plurality of such ammunition rounds each comprising a zinc case and a non-metalic cover portion;
- (b) inserting a first such ammunition round into a chamber of the tool;
- (c) causing ignition of the charge of the first ammunition round;
- (d) inserting a second such ammunition round into the chamber;
- and
- (e) causing ignition of the charge of the second ammunition round so as to expel the spent case of the first ammunition round out of a muzzle of the tool at a muzzle kinetic energy, wherein ignition of the charge of the second ammunition round causes the severing of the non-metalic cover portion permitting a first portion of a non-metallic cover portion of the second ammunition round to separate from a remaining second portion and travel behind the spent case of the first ammunition round.
A method for operating an industrial ballistic tool to discharge a plurality of ammunition rounds, each having a case and a charge of propellant comprising:
- (a) providing a plurality of ammunition rounds having a non-metalic cover portion;
- (b) inserting a first such ammunition round into a chamber of the tool;
- (c) causing ignition of the charge of the first ammunition round;
- (d) inserting a second such ammunition round into the chamber, so as to advance the spent case of the first ammunition round toward a muzzle of the tool;
- and
- (e) causing ignition of the charge of the second ammunition round so as to expel the spent case of the first ammunition round out of the muzzle, wherein ignition of the charge of the second ammunition round causes the severing of the non-metalic cover portion permitting a first portion of a non-metallic cover portion of the second ammunition round to separate from a remaining second portion and travel behind the spent case of the first ammunition round.
