A cartridge chamber, specifically a cartridge chamber of a hand-held firearm for loading cartridges consisting of a bullet and a cartridge case comprising an inner surface of the cartridge chamber where the cartridge chamber in the direction from the barrel mouth, terminates with a head of the breechblock, where the inner surface of the cartridge chamber comprises at least one shaped recess for carrying out the marking of the cartridge case. A cartridge case, specifically a cartridge case of a cartridge, after shooting a bullet fired from the cartridge chamber, which contains on its outer surface at least one trace of the shaped recess of the inner surface of the cartridge chamber.

A test system is disclosed that has a chassis, a throwing mechanism that is located at an upper part of the chassis onto which at least one weight is attached and which provides throwing the weight attached thereon, a base is located at a lower part of the chassis and onto which a weight is thrown by the throwing mechanism, a control unit for throwing the weight by the throwing mechanism, and at least one pushing member for throwing the weight by pushing which is located on the throwing mechanism and operated by the control unit.

A method of manufacturing cartridge cases, wherein the method comprises fabricating a plurality of substantially identically sized and shaped unmarked inventory cases suitable for use in manufacturing a plurality of different caliber cartridges and selecting a number of the plurality of the unmarked inventory cases to be used to manufacturing a selected one of the plurality different caliber cartridges. The method further comprises inscribing, via a laser inscription device, the selected number of unmarked inventory cases to identify at least the selected one of the plurality of different caliber cartridges the selected number of unmarked inventory cases are to be used to manufacture.

A machine vision system for automatically identifying and inspecting objects is disclosed, including composable vision-based recognition modules and a decision algorithm to perform the final determination on object type and quality. This vision system has been used to develop a Projectile Identification System and an Automated Tactical Ammunition Classification System. The technology can be used to create numerous other inspection and automated identification systems.

Methods and systems for collecting high definition images of spent firearm cartridges under different illumination conditions described herein. Features indicative of firing pin impact with each spent firearm cartridge are extracted and compared to features extracted from different spent firearm cartridges. The likelihood that the cartridges were fired from the same firearm is determined based on the differences between the extracted features. A cartridge fixture locates a spent firearm cartridge inside an imaging chamber illuminated by different combinations of illumination devices located in different locations with respect to the spent firearm cartridge. Collected images are filtered by a trained image feature filter to extract features indicative of a firing pin strike. Features extracted from different spent firearm cartridges are compared to determine the likelihood that the spent firearm cartridges were fired from the same firearm based on one or more error metrics characterizing feature differences.
