Real-World Testing: Putting Mec Loader 600jr Mkv .410 3″ 1116 -set Up For 3″ to the Test
First Use Experience
My primary testing ground for this reloading press was at the Sheriffs Range in San Bernardino, specifically set up for loading .410 3-inch shells for recreational pot shooting. This environment involves consistent, repetitive use under varying conditions, from sunny afternoons to cooler evenings. I focused on loading 6-shot shells using 296 powder, aiming for a maximum load of 18 grains, which my tests indicated should achieve approximately 1400 feet per second (FPS).
The MEC Loader 600jr Mkv .410 3″ 1116 -set Up For 3″ proved surprisingly straightforward to set up. The instructions were clear, and aligning the dies for the .410 3-inch shells was intuitive. There was minimal learning curve; the compound leverage system made the resizing and priming stages feel remarkably smooth, even on the first shell.
During the initial loading sessions, I encountered no significant issues. The press operated with a satisfying mechanical feel, and each stage of the reloading process—from de-capping and resizing to powder charging, wad insertion, and crimping—was accomplished with predictable precision. The only minor surprise was the amount of physical effort required for the initial resizing stroke, which, while manageable due to the leverage, was more pronounced than I anticipated.
Extended Use & Reliability
After dedicating several range days and evenings to loading batches of .410 shells with this machine, its reliability has become evident. It consistently performs its core tasks without faltering, which is precisely what one hopes for in a reloading tool. The compound leverage mechanism remains smooth, and there’s no noticeable stiffness developing even after hundreds of cycles.
Durability has been impressive so far. Despite being set up on a sturdy workbench that has seen its fair share of heavy use, the press shows no signs of wear that would impact performance. The cast metal components feel robust, and the moving parts show no excessive play or degradation.
Maintenance is pleasantly simple. A quick wipe-down with a dry cloth after a loading session keeps dust and powder residue at bay. Occasional lubrication of the pivot points with a light machine oil has kept the operation silky smooth. Compared to some simpler, less robust manual loaders I’ve used in the past, this MEC unit feels like it’s built to last for many years of consistent use.

Specifications
The Mec Loader 600jr Mkv .410 3″ 1116 -set Up For 3″ is a specialized piece of equipment designed for reloading .410 gauge shotshells, specifically set up for 3-inch shells. Its core functionality is built around a compound leverage system, which significantly multiplies the force applied by the operator, making the reloading process smoother and less strenuous. It operates as a single-stage loader, meaning each station performs one distinct part of the reloading process sequentially.
Included with the unit are 10, 11, and 12 gauge powder bushings, allowing for precise measurement of different powder charges. It also features an 11/16 oz bar for consistent shot dispensing. The MEC brand itself is well-regarded in the reloading community for its durable and effective equipment. The robust construction and well-engineered leverage system are key specifications that directly translate into ease of use and consistent shell quality. Compared to some entry-level presses that might rely on simpler mechanics, this model offers a more refined and powerful operation.
Performance & Functionality
The primary job of the Mec Loader 600jr Mkv .410 3″ 1116 -set Up For 3″ is to produce consistent, reliable reloaded .410 shotshells. In my testing, it excels at this task. The resizing of fired hulls is thorough, ensuring a good fit for new primers, and the priming process is consistently seated.
Its biggest strength lies in the smooth and powerful operation of the compound leverage. This makes closing crimps tight and consistent, which is vital for proper shell function. The powder bushings provided allow for accurate charge weights, and the shot bar dispenses a remarkably consistent amount of shot with each pull.
A minor area for improvement could be the initial setup calibration for exact powder measurements, which sometimes requires a few trial runs with the bushings. However, once dialed in, the functionality is excellent, exceeding expectations for a single-stage press in this caliber. It reliably produces shells that perform as well as factory loads, a testament to its precise engineering.
Design & Ergonomics
The design of the Mec Loader 600jr Mkv .410 3″ 1116 -set Up For 3″ prioritizes function and durability. It’s constructed primarily from heavy-duty cast metal, giving it a substantial feel and an inherent stability that prevents it from shifting during operation. The finish is a utilitarian, durable coating that seems resistant to scratches and minor dings.
Ergonomically, the large handle of the press is comfortable to grip, and the compound leverage makes actuating the ram smooth, even with heavier loads or stiffer hull materials. There’s a slight learning curve in understanding the sequence of operations – resizing, priming, powder, shot, and crimping – but the logical layout of the press makes this intuitive after just a few shells. The clear markings on the powder bushings are also a practical design element that aids in quick identification.
The overall feel is that of a tool built for longevity and repetitive use, not just for occasional tasks. It’s designed to be operated efficiently, with each component serving a clear purpose in the reloading sequence.
