Exploring the Mec Super Sizer 12ga.: My Review

As a gear and equipment specialist with over a decade of experience across diverse environments – from the precision of a laboratory bench to the rugged demands of outdoor fieldwork, and the intricate needs of a workshop – I’ve developed a keen eye for what makes equipment truly stand out. My workbench is a testament to this, often filled with tools that have seen extensive, real-world use. It was within this context of continuous refinement and the pursuit of efficiency that I found myself needing a reliable method to restore fired shotshells to their optimal dimensions, particularly for use in my collection of vintage 12-gauge shotguns. The Mec Super Sizer 12ga., a name synonymous with shotshell reloading for many, presented itself as a potential solution. I was intrigued by its promise of restoring base dimensions with an “eight-finger design” and its compatibility with various shotshell lengths. My initial impression upon handling this unit was one of robust simplicity; it’s clearly built with functionality in mind, featuring a durable steel frame that speaks to its intended longevity. While I briefly considered other sizing methods, like manual collets or universal sizers, the dedicated nature and established reputation of this Mec product tipped the scales. My first reaction was one of practical curiosity, eager to see if its design translated into effortless operation for a common reloading task.

Real-World Testing: Putting Mec Super Sizer 12ga. to the Test

First Use Experience

My initial testing of the Mec Super Sizer 12ga. took place on my dedicated reloading bench, a space I’ve meticulously organized over the years for optimal workflow. The scenario was straightforward: taking a batch of fired 12-gauge shotshells, many of which had been subjected to various chambers and extraction pressures, and preparing them for reuse. I ran the unit through its paces with a variety of shell types, including common paper and plastic hulls of different lengths. The process was remarkably intuitive; the design of the sizer itself guides the user, making the learning curve practically non-existent. From the very first shell, I experienced a satisfyingly smooth operation, with the collet mechanism engaging the base of the shotshell with consistent pressure.

One of the most immediate positive observations was the evenness of the sizing pressure. Unlike some simpler collet sizers I’ve encountered, the eight-finger design on this Mec model ensures the base is returned to its original diameter without deformation or undue stress on the hull. There were no initial hiccups or surprises; the tool performed exactly as its design suggested, easily handling the task of resizing the spent primer area and the hull base back to their intended dimensions. This was a welcome departure from some older equipment I’ve used, where a bit of fiddling was often required to achieve consistent results.

Extended Use & Reliability

After several weeks and multiple reloading sessions, the Mec Super Sizer has become an indispensable part of my shotshell preparation routine. It consistently handles batches of 100+ shells without any noticeable degradation in performance. The steel construction has proven its worth; despite the occasional accidental bump against other bench equipment, there are no visible signs of wear, deformation, or superficial damage. The sizing mechanism remains smooth and precise, indicating a robust internal design and quality materials.

Maintenance of this shotshell sizer is commendably simple. A quick wipe-down with a dry cloth after use is usually sufficient to keep it free of debris. I occasionally apply a light coat of lubricant to the moving parts to ensure continued smooth operation, a practice that takes mere seconds but pays dividends in longevity. Compared to some of the more complex sizing dies or standalone machines I’ve used in the past, the straightforward nature of this Mec unit makes it a pleasure to maintain. I haven’t encountered any specific failure points; the steel fingers remain firm, and the power ring collet consistently applies the necessary pressure. It has certainly outperformed some of the more budget-friendly, single-piece collet sizers I’ve owned, which often developed slight wobbles or inconsistent pressure application over time.

Breaking Down the Features of Mec Super Sizer 12ga.

Specifications

The Mec Super Sizer 12ga. is engineered with shot shell reloading in mind, and its specifications reflect this purpose. Its primary function is to restore the base diameter of fired 12-gauge shotshells to their original factory specifications. The core of its design is the eight-finger steel collet device, a key component that applies uniform pressure around the base of the shell. This ensures that the wad pressure ring and the base wad itself are effectively reformed, which is crucial for proper re-chambering in any shotgun.

The sizer is designed to accept all common lengths of shotshells within the 12-gauge caliber, a significant advantage for reloaders who may use a variety of hull lengths for different hunting or sporting applications. The durable steel frame contributes to its overall sturdiness and longevity, meaning it can withstand the rigors of regular use without issue. Necessary hardware for mounting and operation is typically included, making it ready for installation on most reloading benches.

Performance & Functionality

In terms of its core function, the Mec Super Sizer 12ga. performs exceptionally well. Its primary job – resizing the base of fired 12-gauge shells – is executed with remarkable consistency. The eight-finger steel collet is the star here, applying even pressure that reliably returns the shell base to its correct diameter. This is critical for preventing difficult chambering issues in shotguns, which can be a significant frustration during a shooting session.

The strength of this tool lies in its predictable and reliable performance. Every shell I’ve processed through it has emerged with a properly sized base, ensuring a smooth fit in my shotguns. While it might not offer the speed of a fully automated sizing station, its efficiency for the task at hand is excellent, especially when considering it’s a component of a conventional loader. The main drawback, if one could call it that, is its singular focus; it only resizes the base and does not perform other hull preparation tasks, such as decapping or crimping, which are handled by other parts of a reloading press.

Design & Ergonomics

The design of the Mec Super Sizer 12ga. is a testament to function over form, but without being aesthetically unappealing. The red finish is classic for Mec reloading equipment, and the steel construction provides a solid, weighty feel that instills confidence. It’s not a delicate piece of equipment; it’s built to be used, and its robust construction suggests it will endure years of service.

From an ergonomic standpoint, the unit is designed for integration into a reloading press. Once mounted, its operation is primarily dictated by the leverage provided by the press handle. The collet action itself is smooth, requiring minimal effort once the initial engagement of the eight steel fingers with the shell base occurs. There’s no complex manipulation required from the user beyond operating the press handle, making it straightforward to use even during long reloading sessions.

Durability & Maintenance

The Mec Super Sizer 12ga. is built for the long haul. Given its solid steel construction and the absence of delicate moving parts, its durability is a significant selling point. Under normal reloading conditions, where the unit is used for its intended purpose and kept reasonably clean, I anticipate it lasting for decades. The steel fingers show no signs of fatigue or wear, and the mechanism for engaging them remains robust.

Maintenance is refreshingly simple. A quick wipe-down after use is typically all that’s needed. Periodically, applying a small amount of light machine oil to the pivot points and the collet mechanism will ensure continued smooth operation and prevent any potential seizing over time. There are no disposable parts in the sizer itself, meaning the only maintenance required is keeping the existing components clean and lubricated. I haven’t encountered any potential failure points, and the design seems inherently resistant to common issues like bending or cracking.

Accessories and Customization Options

The Mec Super Sizer 12ga. is primarily a functional component of a larger reloading system, rather than a standalone product with extensive accessory options. It is designed to integrate seamlessly with MEC shotshell reloading presses. The primary “accessory” to consider is the press itself, which houses the sizer.

Customization isn’t really a factor for this specific component. Its role is specific and singular: to resize the base of 12-gauge shotshells. While MEC offers various gauges for their Super Sizer line (10, 12, 16, 20, 28, and .410 bore), you purchase the sizer specific to your caliber. Therefore, the most important consideration is ensuring you have the correct gauge, which in this case is the 12ga. model.

Pros and Cons of Mec Super Sizer 12ga.

Who Should Buy Mec Super Sizer 12ga.?

The Mec Super Sizer 12ga. is an excellent choice for any reloader who focuses on shotshells and specifically uses or intends to use MEC reloading presses. This includes trap, skeet, sporting clays, and waterfowl hunters who reload their own ammunition and want to ensure their fired hulls are properly prepared for reuse.
