Abstract: A holster comprising a body portion, the body portion comprising a port shell and a starboard shell that cooperate to define a cavity for receiving and holding the handgun. The holster comprising a pair of flat ears, the ears including a forward ear extending forward of the cavity and a rearward ear extending rearward of the cavity. The forward ear defining a forward slot and the rearward ear defining a rearward slot, each slot having a forward edge and a rearward edge. Each slot being configured and dimensioned to receive one of a belt and a clip. Each ear having changes in thickness adjacent the forward and rearward edges of each slot. The changes in thickness defining multiple discrete positions for receiving a holster body attachment portion of the clip.

Abstract: A cartridge casing of a cartridge for a lever action firearm, the cartridge casing comprising a rim comprising a flat front face configured to provide a gripping surface for an extractor of the lever action firearm to remove the cartridge casing of the cartridge after firing of the lever action firearm, the rim having a radial gradient that decreases from a maximum radius at a first location on the rim that is prior to the flat front face to a minimum radius value at a second location on the rim corresponding to the flat front face.

Abstract: A cartridge comprising a bullet, the bullet providing a radially expanding array of bullet fragments upon entering a target and also providing an increase in effective surface area of the bullet within the target by structural features that facilitate tumbling or mushrooming in the target. In an embodiment a pair of axial core members are aligned in a bullet jacket with the forward core member being segmented with separation junctures formed by engaged faces of adjacent segments. Impact causing fracturing of the segments from a base portion.

Abstract: A .22 caliber rimfire cartridge includes a generally cylindrical casing having a rearward rimfire end and an opposing mouth end, wherein the rearward rimfire end has an annular rim connecting to a cylindrical casing portion extending to a casing forward edge and a bullet is disposed in the forward mouth end. In embodiments, the bullet comprises copper and a polymer binder. In embodiments, the bullet has a forward tapering portion with a central cavity, a first cylindrical portion with a first diameter and a cylindrical surface directly rearward of the tapering portion, a cylindrical driving band directly rearward of the first cylindrical portion, the cylindrical driving band having a second diameter greater than the first diameter and having an outer second cylindrical surface, a third cylindrical portion directly rearward of the cylindrical driving band, the third cylindrical portion having a third cylindrical surface with a diameter equal to the first diameter.

Abstract: A high capacity magazine for high powered rimfire cartridges comprises a header portion that has a form factor to be received in a rotary magazine receptacle and an arcuate cartridge bank portion that holds a column of cartridges. A pair of clamshell halves define an arcuate cartridge bank and a lower portion of the header potion. A header caps the upper ends of the clamshell halves securing the clamshell halves together. The head and clamshell halves define the cartridge pathway to the magazine exit to be fed into the rifle chamber.

Abstract: An electronic magazine loader for loading cartridges into a magazine includes a lifting wheel, a chute, and a magazine loading portion. The wheel receives an unordered batch of cartridges and singularly lifts and deposits the cartridges into the chute. The chute transfers the cartridges to the magazine loading portion where a setting mechanism inserts the cartridges into the magazine. A mechanism for directionally orienting the cartridges orients all cartridges to a proper directional orientation before reaching the magazine loading portion. The mechanism can be lifting wheel shelf structure or chute structure. The chute having a C-shaped portion above the magazine loading portion that precludes the cartridges from changing their proper directional orientation. The setting mechanism receives cartridges on a rotating wheel with rotating insertion lobes and cartridge receiving voids between adjacent lobes. The cartridges drop into a cartridge receiving void, and are urged into the magazine by a rotating lobe.

Abstract: A muzzleloader firearm for use with a projectile, a propellant containment vessel including a prepackaged propellant charge therein, and a primer. The muzzleloader has a stock and a barrel supported by the stock. The barrel has a breech end, a muzzle end, and a barrel wall extending in a forward direction from the breech end to the muzzle end. A breech plug is at the breech end. The barrel being ported to transfer expanding gases from the barrel to the breech plug. A gas passageway in the breech plug directs expanding propellant gases to the propellant chamber behind the propellant vessel seated therein wherein the expanding gases can eject the used propellant vessel.

Abstract: A motorized magazine loader for loading cartridges into a magazine includes a powered sorting and lifting wheel rotatable about a horizontal axis of rotation, a vertical gravity fed cartridge chute positioned laterally next to the sorting and lifting wheel, an accumulator portion at a lower end of the chute, and a loading portion comprising a receiver for magazines to be loaded and a pusher mechanism for inserting cartridges into the magazines, all supported and substantially contained by a housing.
