Biodegradable shotgun wad system

Herein we describe embodiments of shotgun shells, methods for loading such shotgun shells, and methods for using them. In some embodiments, the shotgun shells utilize a multi-component wad system with a biodegradable powder wad that stays intact through the firing process, and a separate and chemically distinct biodegradable shot wad that breaks apart within one meter after being shot out of the barrel of a shotgun. A clean release of the shot can be obtained, providing both high performance and biodegradability. The biodegradable shot wad can be a biodegradable polyester.

BIODEGRADABLE SHOTGUN GAS SEALING WAD

Herein we describe embodiments of a biodegradable wad having a gas sealing function, as well as methods for their use. In some embodiments, the biodegradable wad comprises at least 50% by weight of a poly(butylene succinate co-adipate) polymer. In some embodiments, the biodegradable wad comprises at least two biodegradable polymers, wherein a first biodegradable polymer comprises a polybutylene succinate adipate polymer and a second biodegradable polymer comprises a polyhydroxyalkanoate polymer. Plastic debris has a negative economic and ecological impact, and thus it is advantageous to use implements that will degrade into environmentally benign compounds. Incorporating a biodegradable wad into shotgun shells provides an effective, economical solution, provided cost is acceptable and performance is not compromised. Suitable shotgun shells utilizing biodegradable shotgun wads and methods are described herein.

The present invention concerns a cartridge for firearms comprising a cartridge case with a crown of wings. The wings themselves are fused or glued to one another so as to form an ogival closing element of the cartridge case. The invention also concerns the process for manufacturing the cartridge and the relative equipment.

Shotgun Shell Loading Block Device
20250102280 · 2025-03-27 ·

A shotgun shell loading block device is provided. The device may be comprised of a base, a central block, and at least one outside block. The central and outside block have recessed areas which, when the blocks are placed together, form a cylindrical opening that can hold at least one shotgun shell vertically. The blocks may be connected using a rod and fastener. As a result, a user can load a plurality of shells vertically into the blocks. Then, a user can load the shells and quickly and easily crimp roll the shells (while they remain secured between the blocks) using a drill or other similar tool.

Combined Shot-Wadcutter Ammunition and Methods for Manufacturing the Same
20250251227 · 2025-08-07 ·

A small arms cartridge load that fires bird shot and a full wadcutter bullet. The cartridge is loaded with both a wadcutter and shot. A cup crimped to the casing is used to secure the contents inside the casing. No plastic capsule is needed to secure the shot in place. Removing the plastic capsule prevents the shot from taking the rifling and thus keeping the pattern tighter to extend the effective distance of the shot. The wadcutter can be hard cast to provide greater penetrating force. The load can be effective in deterring varmints or for defensive purposes.
