Forster Co-Ax Reloading Press with "S" Jaws, Model B5

• Co-Ax alignment system: The Co-Ax press design lets the case and die self-center during the stroke, which helps reduce side loading and supports more consistent sizing and bullet seating.
• Factory-installed “S” jaws: The included “S” lower shell holder jaws are set up for case rims from .468" to .562", giving broad compatibility for common reloading work without changing traditional shellholders.
• Single-stage precision: As a single-stage reloading press, this model is built for deliberate, repeatable operation where control matters more than output speed, especially for load development and accuracy-focused ammunition.
• Made in the USA: U.S. manufacturing supports the solid, workshop-oriented character of the press and suits reloaders looking for durable bench equipment for long-term use.
• 10-year warranty: A stated 10-year warranty adds clear long-term support, which is important for a press intended to stay on the bench through years of regular sizing and seating work.

About the Co-Ax Series

The Forster Co-Ax series sits among the company’s best-known reloading tools and is aimed at reloaders who prioritize repeatable alignment, smooth operation, and careful control over each stage of the loading process. Rather than following the conventional shellholder-and-ram layout used by many presses, the Co-Ax system is built around a floating, self-centering approach that helps the case and die align naturally during sizing and seating. In practical terms, that design is valued by handloaders working on precision rifle ammunition, load development, and other tasks where consistency from round to round matters.

Within Forster’s lineup, the Co-Ax press family complements the brand’s broader focus on precision reloading equipment such as dies, trimmers, and measuring tools. The series is known for its distinctive jaw-based case holding system, straightforward bench use, and a mechanical layout intended to reduce unnecessary setup complications. For reloaders who want a single-stage press with a strong emphasis on concentricity and controlled feel at the handle, the Co-Ax series has a long-established place on the loading bench.

About the Forster Co-Ax Reloading Press with "S" Jaws, Model B5

The Forster Co-Ax Reloading Press with “S” Jaws, Model B5 is built for reloaders who want the deliberate pace of a single-stage press combined with the alignment advantages that made the Co-Ax name well known. Its core benefit is not speed, but consistency: the press is designed so the case can float into alignment with the die, helping reduce the tendency for components to be forced off-center during sizing or bullet seating. That makes it especially well suited to accuracy-focused handloading, whether the goal is refining match ammunition, building hunting loads, or simply improving repeatability at the bench.

This version is supplied with factory-installed “S” lower shell holder jaws. These jaws are ready for case rims from .468" to .562", which covers a broad range of common applications while preserving the Co-Ax system’s self-acting case handling. In use, the spring-loaded jaws automatically open and close on the case head, supporting smooth insertion and extraction while maintaining the floating action that is central to the press design.

Model B5 also reflects the practical character expected from a bench press intended for long service. It is made in the USA, carries a stated 10-year warranty, and focuses on controlled, repeatable operation rather than unnecessary complexity. For reloaders who value precise die-to-case alignment and a clean, purpose-built approach to single-stage reloading, this Co-Ax press remains a highly relevant choice.
