Forster Co-Ax E-Z-Just Shell Holder Priming Conversion Kit

• Co-Ax priming system conversion: This kit updates a compatible Forster Co-Ax press for priming use, adding the parts needed to integrate primer seating into the press workflow and reduce bench changes between operations.
• E-Z-Just shell holder compatibility: Built around the Co-Ax E-Z-Just shell holder system, it supports quick case changes without swapping conventional shell holders, which helps keep setup simple when loading different cartridges.
• Compact accessory for case-prep benches: With a listed weight of 5.00 g, the kit adds the required conversion components without taking up meaningful space, making it easy to keep with other priming and decapping tools.
• Made in the USA: U.S. manufacture aligns with Forster's long-standing focus on precision reloading tools, giving reloaders a component intended to match the fit and function expected in the Co-Ax system.

About the Co-Ax Series

Forster's Co-Ax series is built around a different approach to reloading press design: instead of relying on a conventional single-ram layout, the system emphasizes straight-line case and die alignment, easy die changes, and adaptable case holding. Within the brand's reloading lineup, the Co-Ax platform is aimed at reloaders who want repeatable setup and consistent handling across sizing, seating, and priming tasks.

A defining characteristic of the series is its use of shell holder jaws rather than the usual caliber-specific shell holder arrangement. In practice, this reduces setup interruptions and makes the press more flexible when moving between cartridges. The Co-Ax family is also known for accessories and conversion parts that let users tailor the press to specific bench routines, including case preparation and priming operations. That modular approach is part of what has made the series relevant for careful handloaders who value mechanical consistency, straightforward adjustments, and a bench setup that can be adapted without replacing the core press.

About the Forster Co-Ax E-Z-Just Shell Holder Priming Conversion Kit

The Forster Co-Ax E-Z-Just Shell Holder Priming Conversion Kit is a purpose-built accessory for reloaders who want to add or restore priming capability to a compatible Co-Ax press setup. Rather than being a general bench accessory, it is designed for a specific role within the Co-Ax system: integrating primer seating into the same press platform used for other loading operations. That makes it especially useful for reloaders who prefer a more unified workflow and want to keep case handling consistent from one step to the next.

The key advantage of this kit is its relationship with the E-Z-Just shell holder arrangement. Because the Co-Ax system uses jaws instead of standard shell holders, case support and cartridge changes can be handled more efficiently across a broad range of cases. For priming work, that means less time spent changing hardware and more time maintaining a steady loading rhythm. In practical use, this kind of setup can help reduce interruptions at the bench, especially for reloaders working with multiple rifle or pistol cartridges.

As a Co-Ax press accessory, the kit also fits naturally into Forster's broader design philosophy of modular, precision-oriented reloading equipment. Its compact form makes it easy to store with other press parts and case-preparation tools, while its U.S. manufacture matches the brand's established focus on reloading tools built for long service and repeatable mechanical function.

About Forster

Forster Products dates its history to 1935 and focuses on precision reloading and gunsmithing tools. The company is based in Lanark, Illinois, and states that its products are made in the United States. Within the reloading category, Forster is especially closely associated with the Co-Ax Press, one of its established product lines for handloaders who value consistent alignment and bench efficiency.

Beyond the Co-Ax system, Forster's range includes reloading dies, case trimmers, headspace gages, and sight-mounting fixtures. The company also developed products such as its Bench Rest Seater Dies, which use a close-fitting chamber to help align the case and bullet during seating. That concentration on precise cartridge handling and measurement is what makes the brand particularly relevant in reloading equipment and press accessories.
