Abstract
A process for loading a primer into an ammunition cartridge while concurrently forming a diffuser disk includes stamping a sheet to pre-form a diffuser disk therein. The primer, pre-formed diffuser disk and primer pocket of the cartridge are aligned with one another and thereafter, the primer is pressed through the pre-formed diffuser disk into the primer pocket. As the primer is pressed into the pre-formed diffuser disk, the primer severs one or more attachment points to release the pre-formed disk from the sheet and form the diffuser disk while the primer is loaded.
Claims20
A process for loading a diffuser disk into an ammunition cartridge, comprising:
- stamping a sheet to pre-form a disk having a diffuser aperture, wherein the pre-formed disk remains connected to the sheet by an attachment point;
- centering the diffuser aperture between a primer and a primer pocket of the ammunition cartridge;
- and
- pressing the primer and the pre-formed disk into the primer pocket thereby cutting the attachment point to form the diffuser disk concurrently with installation of the primer.
A pre-formed diffuser disk configured for insertion into a primer pocket of an ammunition cartridge, the pre-formed diffuser disk comprising:
- a sheet;
- a disk formed in the sheet and retained therein by at least one attachment point connecting a perimeter of the disk to the sheet;
- a center hole defined through the disk;
- and
- a means, formed in the sheet, for aligning the center hole to the primer pocket.
A pre-formed diffuser disk for insertion into a primer pocket of an ammunition cartridge, comprising:
- a thin metal sheet;
- one or more disks formed in the sheet, wherein each disk is connected to the sheet by two or more attachment tabs, each attachment tab separated from an adjacent attachment tab by a recessed curvature defined through the sheet forming an outer disk perimeter;
- a center hole defined through each of the one or more disks;
- two or more alignment tabs formed in the sheet and configured to concentrically align each center hole with a primer pocket, wherein an outer diameter of each disk is substantially equal to a maximum inner diameter of the primer pocket;
- and
- one or more indents formed in a bottom surface of each of the disks, wherein the one or more indents are configured to engage at least one anvil leg of a primer.
