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, a dispenser controller, and a tangible storage medium storing instructions executable by the dispenser controller. The dispenser controller can execute a powder calibration sequence and/or a dispensing sequence. In the powder calibration sequence and/or the dispensing sequence, the dispenser controller desirably learns the dispense rate of the powder and uses the dispense rate to optimize dispensing of the powder and increase precision in dispensing a target mass of powder. The conveyor can comprise a conveyor tube having a conveyor tube axis oriented to extend at an upward angle with respect to horizontal.

Shell Reloader Device
20220178667 · 2022-06-09 ·

A shell reloader device simultaneously performs multiple steps to allow reloading of a plurality of ammunition shells in a reduced time. The shell reloader device includes a press including a fixed section, a linkage, and a handle pivotally coupled to the fixed section. The handle is coupled to the linkage wherein the linkage is moved relative to the fixed section by operation of the handle. A compressor is operationally coupled to the press such that the compressor provides compression to each of a plurality of stations when the handle is operated. Each of the stations holds a respective shell in a position to be acted upon by the compressor for respective associated steps in reloading each shell.

Method of making polymeric subsonic ammunition

The present invention provides a method of making a subsonic ammunition having a polymeric casing body having a generally cylindrical hollow polymer body having a body base at a first end thereof and a mouth at a second end to define a propellant chamber; a propellant insert positioned in the propellant chamber to reduce the internal volume of the propellant chamber, wherein the propellant chamber has an internal volume that is at least 10% less than the open internal volume of a standard casing of equivalent caliber; and a primer insert positioned in the body base and in communication with the propellant chamber.

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.

Rotary-drive ammunition reloading systems with discontinuous stroke speed

An ammunition reloading system is configured to be operatively coupled with an ammunition reloading press to enable automated operation of the press. The reloading system includes a motor and a power transmission assembly that enables rotational power in a single direction from the motor to drive the ammunition reloading press. A controller is communicatively coupled to the motor and to one or more press position sensors to determine a position of the press within a press stroke cycle and increase or decrease the speed of the motor accordingly.

FIRE ARM CASING AND METHOD FOR MANUFACTURING
20210254950 · 2021-08-19 ·

This invention relates to a cartridge casing that has a substantially hemispherical end that integrally mates to a welded conforming base that stores a primer. One or more holes in the hemispherical end of the upper chamber aligns with a corresponding hole in the base having a lower pocket to allow primer gasses into the shell casing. The configuration of the base, in combination with upper chamber's distal end hemispherical concavity, removes from the prior art a nipple attachment to the upper chamber and sharp corners in the casing that allow for greater reliability in the integrity in the firing of the bullet, as well as the potential for a greater explosive effect due to a shorter passage to ignite the gun powder more uniformly by the primer source.
