Cartridge loading process for buffered shot shell loads
Disclosed are processes for loading a cartridge such as a shot shell with a shot load and a charge of buffer material. The processes employ a tube that is coaxially aligned with the axis of the cartridge case or shot cup, the tube having an outer diameter that closely fits into the inner diameter of the cartridge case or shot cup. Shot and buffer material are loaded, the leading edge of the tube is inserted to a sufficient depth to cause at least a portion of the shot load and buffer material to rise into the inner volume of the tube, and the tube removed. The insertion-removal cycle effects the efficient mixing of the shot and the buffer material and can be repeated as many times as desired.
Dual barrel powder dispenser
A dual-barrel powder dispenser is provided. The dual-barrel arrangement may offer a highly-accurate, and highly efficient system and method for dispensing a consistent amount of powder. A controller in communication with the interface may determine the speeds at which each barrel rotates in order to dispense a volume and weight of powder from a hopper to a receptacle. A scale may monitor and determine the total weight of powder dispensed into the receptacle resting on the scale. The entire assembly may be self-contained in a single integrated body.
METHODS AND DEVICES FOR AMMUNITION UTILIZING A PARTICULATE OBTURATING MEDIUM
Herein we describe cartridges, including for shotgun shells, utilizing a particulate obturating medium to provide a gas seal. The obturating medium comprises particles having an average particle size greater than 212 microns, and an average specific gravity greater than 1.1. Such cartridges are particularly useful as shotshell cartridges used as blanks, less lethal loads, hunting loads, target loads, and barrel-cleaning loads. Methods for loading and use are described, as well as different particulate obturating media.
Empty casing feed for a reloader
A discrete empty casing feeder for a cartridge reloader is controlled electronically by a control module. Empty casings are loaded on top of each other in a conventional feeder tube and are gravity fed through the feeder tube onto an upper rotating carousel. The discrete empty casing drops into a cylinder in the upper carousel and the carousel and casing rotate until the casing reaches a hole in the floor under the upper carousel. The discrete empty casing drops onto a solenoid lever in a tube. When the typical lower turret is raised mechanically, a sensor detects that the lower turret and push ram are in the correct position. The trap lever opens and drops the empty shell casing into a slot in the front of the push ram. The push ram then pushes the correctly oriented discrete casing onto the conventional turret. As the shell casings go through a normal reloading cycle, a fully loaded cartridge is ejected from the lower turret and the entire process begins again.
Integrated polymer and metal case ammunition manufacturing system and method
A fully automated, integrated, end-to-end synchronized and compact manufacturing system produces polymer or metal case ammunition. Manufacturing stations support case assembly, sealing (gluing/welding), final product inspection, cartridge packaging or binning, and loading. Station modularity facilitates rapid changeover to accommodate ammunition of differing calibers. Sensors and apparatus may be provided to place a manufacturing cell in a wait state until all components or materials are received in a preferred orientation for proper assembly. The system may join and use multipart cases, each including a lower portion with a head end attached thereto and at least one upper portion having a necked-down transition to the open top end. Elevator feeders, vibratory bowl feeders, and robotic pick-and-place feeders may be used to deliver components for assembly.
Methods and devices metering and compacting explosive powders
A powder compaction device is disclosed. The device has a drive motor operable connected to a compaction rod that moves through a loading platform to a cartridge holding platform. A powder loading station is positioned below the loading platform and above the cartridge holding platform. The compaction rod moves through the powder loading station, which loads a predetermined volume of propellant powder into one or more reliefs defined in the compaction rod. The cartridge holding platform has a removable cartridge fixture designed to receive an ammunition cartridge to be loaded and compacted with propellant powder. The propellant powder is released into the cartridge fixture from the reliefs as the compaction rod passes a funnel defined at an upper end of the fixture. After releasing the powder, the compaction rod continues into an interior chamber of the fixture to compact the powder contained therein.
Munition and logistics concept for, in particular, artillery projectiles
A uniform projectile casing which is utilized for projectiles with different ranges. A projectile of relatively short range can in this case be optimized with regard to payload, whereas a projectile with the relatively long range is subjected to a range optimization, with a reduction in payload. The payload of a projectile of relatively long range is generally lower in relation to a projectile with relatively short range. The artillery projectiles have a projectile casing of equal size for the projectiles of different range. To create an artillery projectile, for example 155 mm, a uniform payload-optimized 30 km projectile casing) is used, from which 40 km projectiles can be generated (produced, assembled) by means of a reduction in payload. The range is selected and defined by mutually different projectile bases. The artillery projectile has multiple modular parts which are assembled in order to create the artillery projectile.
DISPENSER FOR FIREARM AMMUNITION POWDER
A dispenser for dispensing powder for firearm ammunition and associated methods. The dispenser can include a hopper, a conveyor, a scale sensor, a dispensing head, a dispenser controller, and a tangible storage medium storing instructions executable by the dispenser controller. The dispensing head is movable to a plurality of dispensing positions to dispense ammunition powder to a plurality of cases from the plurality of dispensing positions. In some embodiments, the dispensing head moves between a home position, where the dispensing head receives powder from the conveyor, and the plurality of dispensing positions, where the dispensing head delivers loads of powder from the conveyor to individual ammunition cases.
