This allowed me to directly observe any differences in shot and powder consistency before committing to a full production run of ammunition.

During these tests, I focused on loading hundreds of rounds. The charge bar performed consistently through repeated cycles of filling, charging, and emptying. Even when working at a steady pace, without allowing for extensive cooling or dust accumulation, the performance remained unwavering. The action of the bar within the press remained smooth, and there were no signs of binding or galling, even when dealing with fine-grained powders.

Ease of use was a significant factor, and I found this charge bar to be remarkably intuitive. Once installed, adjusting the charge is straightforward thanks to the clearly marked micrometer adjustment. There was no steep learning curve; I was able to dial in my desired charge weight within a few adjustments and confirm it with my scale. The initial setup was simple, and subsequent adjustments were even faster.

One minor quirk I noticed initially was that the 7/8 ounce charge setting on the bar required a slightly more deliberate rotation of the adjustment screw than I was accustomed to. However, this was more a matter of learning the feel of the new mechanism than a genuine issue. Once I understood the resistance and travel of the adjustment screw, it became a precise and predictable process.

Extended Use & Reliability

After weeks of regular use, spanning multiple reloading projects for different gauges and load types, the Mec 502 Charge Bar 7/8 Ounce 50278 has proven itself to be a reliable workhorse.

Breaking Down the Features of Mec 502 Charge Bar 7/8 Ounce 50278

Specifications

The core specification for this charge bar is its designated capacity: 7/8 ounce. This is crucial for shotgun reloading, as it dictates the volume of shot dispensed. The micrometer adjustment is another key feature, allowing for precise increments of change. This mechanism is positioned closer to the charge bar’s ogive, which is designed to engage the shot column directly, theoretically leading to more uniform volume measurement. The product is designed specifically for use with MEC 502 presses, ensuring a perfect fit and seamless integration.

The significance of the 7/8 ounce capacity cannot be overstated for specific shotgun loads, particularly those used in competitive shooting like skeet or certain upland game hunting scenarios. The micrometer adjustment allows reloaders to fine-tune their loads beyond the standard settings, which is invaluable when working with different shot sizes or aiming for minor velocity adjustments. Compared to traditional charge bars with fixed settings, this level of adjustability offers a significant advantage in achieving tailored ammunition. The MEC 502 integration means it’s a direct replacement part, simplifying installation for existing MEC press owners.

Performance & Functionality

The primary job of the Mec 502 Charge Bar 7/8 Ounce 50278 is to dispense consistent amounts of shot, and it excels at this task. During my testing, the charges were remarkably uniform, often within a tenth of a grain of my target weight when using my electronic scale. This level of precision directly translates into more consistent shot patterns downrange. I noticed a significant reduction in flyers during patterning sessions, a testament to the consistent shot delivery.

Its greatest strength is undoubtedly the repeatable accuracy it provides. For reloaders who demand the highest level of consistency, this charge bar delivers. A potential area for slight improvement could be even finer granularity in the micrometer adjustment, though for its intended purpose, it is already exceptionally precise.
