Mec Powder Bushing Number 12A 5012A Review

What to Expect from the Mec Powder Bushing Number 12A 5012A

When precision and consistency are paramount in reloading, the seemingly small components can make the biggest difference. This is precisely the case with the Mec Powder Bushing Number 12A 5012A. As an essential part of the powder dispensing system in MEC reloading presses, its accuracy directly impacts the uniformity of every shell you produce. Made by MEC, a well-respected name in the reloading industry, this bushing is designed to offer reliable performance.

My search for this specific powder bushing was driven by a desire to fine-tune my shot shell reloads for a particular sporting clays load. I was experiencing slight variations in powder charges, which, while perhaps minor, were becoming a nagging inconsistency I wanted to eliminate. After some research, the MEC powder bushing system seemed like the most direct path to achieving greater charge repeatability. I considered a universal powder bar, but the simplicity and proven track record of MEC’s bushing system, coupled with the availability of highly granular adjustments, made it my preferred choice. My initial impression upon holding the bushing was one of understated quality; it felt solid and precisely machined.

First Use Experience

My first experience with this powder bushing took place at my reloading bench, a familiar environment I’ve spent countless hours in over the past decade. I was integrating it into a well-worn MEC 650 Progressive press, a setup I know intimately. The conditions were stable, my workspace well-lit, and the goal was straightforward: dispense powder for a series of target loads.

Installation was, as expected, incredibly simple. The bushing slipped into place with a satisfying, precise fit, a testament to its manufacturing. During the initial cycling of the press, I immediately noticed a difference in the smoothness of the powder drop. It felt more consistent, less prone to sticking or bridging than with the previous adjustment I had been using.

However, I did encounter a minor quirk during the very first few cycles. I noticed a slight hesitation in the powder flow on occasion, almost as if the powder was not fully settling into the bushing’s cavity before the drop. This was a fleeting issue, though, and seemed to resolve itself after about twenty cycles as the powder and bushing surfaces likely found their optimal interaction.

Extended Use & Reliability

After several weeks of consistent use, processing hundreds of rounds of ammunition, the Mec Powder Bushing Number 12A 5012A has proven to be a reliable workhorse. It has maintained its precise metering capabilities throughout this period without any discernible drop in performance. The aluminum construction, while seemingly basic, has held up exceptionally well to repeated contact with various powder types, from fine-grained target powders to slightly coarser rifle powders used in test loads.

Durability has not been an issue. There are no signs of wear, deformation, or any performance degradation that would indicate a need for replacement anytime soon. Cleaning is as simple as a quick wipe-down with a dry cloth or a soft brush, and it stores easily in its designated spot within my reloading accessory drawer. Compared to some of the fiddly plastic powder measures I’ve encountered in lesser systems, this metallic bushing offers a far greater sense of longevity and robustness. It’s the kind of component that you install and then, for all intents and purposes, forget about because it just works.

Breaking Down the Features of Mec Powder Bushing Number 12A 5012A

Specifications

The Mec Powder Bushing Number 12A 5012A is a meticulously crafted component designed for precise powder dispensing in MEC reloading presses. Its core specification lies in its precise internal volume, calibrated to dispense specific amounts of propellant. The material used is aluminum, chosen for its lightweight properties and resistance to corrosion, ensuring a long service life.

This specific bushing carries the designation “12A,” indicating a particular charge volume that is crucial for achieving consistent loads. The silver color is purely aesthetic but contributes to the overall professional finish of the part. The significance of these specifications is profound; a consistent internal volume directly translates to consistent powder charges, which is the bedrock of accurate and safe ammunition.
