Forster Co-Ax Primer Seater includes E-Z-Just jaws Review

Getting My Hands on the Forster Co-Ax Primer Seater includes E-Z-Just jaws

For any serious handloader, the primer seating operation is a critical step. It’s where a tiny component has a massive impact on ignition reliability, and conversely, where a small error can lead to frustrating misfires. My own reloading bench has seen its share of primer seating tools over the years, from simple hand-held devices to more complex press-mounted accessories. However, I was recently finding myself consistently dissatisfied with the slight imperfections in primer seating depth on a batch of .223 Remington brass. The subtle inconsistencies were leading to an unacceptable number of high primers during resizing, causing chambering issues and general annoyance. This led me down the rabbit hole, seeking a tool that promised more precision and control.

While many primer seaters exist, the Forster Co-Ax Primer Seater includes E-Z-Just jaws caught my eye with its distinct design philosophy. Unlike the common shell-holder-based systems, this one boasts a unique method for aligning and seating primers, aiming to eliminate lateral movement and ensure a perfectly flush or slightly below-flush seating every time. My initial impression upon unboxing was one of solid, no-nonsense construction. The piece feels substantial, primarily made of metal with a pleasingly smooth operation. It’s clear this isn’t a flimsy piece of equipment; it looks and feels like it’s built to endure thousands of priming cycles.

I briefly considered a few other high-end priming tools, but their reliance on individual shell holders or a less adaptable jaw system ultimately steered me back towards the Co-Ax. The promise of its E-Z-Just jaws eliminating the need for separate shell holders for most modern cartridges was a significant draw, simplifying the setup process. My immediate feeling was one of cautious optimism; the design seemed sound, but the proof, as always, would be in the actual performance.

Real-World Testing: Putting Forster Co-Ax Primer Seater includes E-Z-Just jaws to the Test

First Use Experience

My initial testing took place on my dedicated reloading bench, a space that sees a steady stream of cartridges being prepped. I focused on a batch of .223 Remington cases, as this was the caliber that had prompted my search for a better priming tool. The setup was surprisingly straightforward; once I understood the mechanism, aligning the jaws to grip the case rim was a matter of seconds.

The built-in primer flipper tray proved to be a convenient feature, feeding small rifle primers into the seating mechanism with minimal fuss. The primary test was seating primers into newly expanded and resized cases. The operation felt smooth and controlled, with a distinct tactile feedback when the primer reached its seated depth. I didn’t encounter any immediate issues or surprises, but I did notice that achieving consistent depth required a deliberate and consistent pressure application.

Extended Use & Reliability

After several reloading sessions, encompassing hundreds of rounds across various calibers like 6.5 Creedmoor and .308 Winchester, the Forster Co-Ax has proven its mettle. The E-Z-Just jaws have reliably gripped a wide range of modern rifle and pistol cases without slippage or damage. Its ability to accommodate rim thicknesses from .045″ to .072″ means I haven’t had to swap out any components for different case types, a significant time-saver.

Durability hasn’t been an issue. Despite regular use and occasional exposure to ambient workshop dust, there are no signs of wear on the critical components. The mechanism remains smooth, and the primer seating is consistently accurate. Cleaning is minimal; a quick wipe-down with a dry cloth usually suffices, and it stores neatly on my bench without taking up excessive space. Compared to some of the more basic press-mounted priming tools I’ve used, this bench-mounted unit offers a superior feel and a much greater degree of control, significantly reducing the risk of over-seating or under-seating primers.

Breaking Down the Features of Forster Co-Ax Primer Seater includes E-Z-Just jaws

Specifications

The Forster Co-Ax Primer Seater includes E-Z-Just jaws is a bench-mounted tool designed for precise primer seating. Its primary material is Aluminum, contributing to its sturdy yet manageable weight. The unit is predominantly red, an aesthetic choice that sets it apart.

A key feature is the E-Z-Just jaws, which securely grip most modern rifle and pistol cases with a rim thickness ranging from .045″ to .072″. This broad compatibility means no additional shell holders are required for a vast majority of reloading tasks, simplifying the process. It also includes a built-in primer flipper tray for easy primer feeding. The primer tubes feature an open slot where primers stack sideways, a design choice intended for added safety. The specifications indicate it is a Large size priming tool, implying compatibility with large primers, though it’s designed for efficient caliber changes.

These specifications translate directly into user benefits. The all-metal construction suggests longevity and resistance to wear, crucial for a tool that sees repetitive use. The E-Z-Just jaws eliminate the hassle and cost of purchasing numerous shell holders, making it a more economical and practical choice in the long run. The safety feature of sideways-stacked primers in the tubes is a thoughtful addition for anyone handling primers.

Performance & Functionality

The core function of the Forster Co-Ax Primer Seater includes E-Z-Just jaws is primer seating, and it excels at this task. The primary strength lies in the precise control it offers over seating depth. Unlike press-mounted seaters where feel can be somewhat muted, this tool provides a direct, tactile sensation as the primer encounters the bottom of the primer pocket.

This precise feel allows for consistently seated primers, flush or slightly below the case head, which is critical for reliable extraction and ignition. The user feedback often mentions the excellent feel and the elimination of issues like primers turning sideways or not dumping correctly, which can plague less refined tools. A potential weakness for some users might be the learning curve involved in consistently applying the correct pressure.
