Real-World Testing: Putting Mec Super Sizer .410 Bore to the Test

First Use Experience

My testing grounds for this sizer were my own reloading bench, a space that sees a constant rotation of brass and a variety of calibers, but this was specifically for my .410 bore projects. I integrated the Mec Super Sizer .410 Bore into my established reloading routine, where I process spent .410 hulls that have already been de-primed and have had their crimps removed. The process was straightforward: mount the sizer on my MEC press, adjust the stroke slightly, and begin feeding the hulls.

Performance was immediately noticeable. The steel construction provided a satisfyingly firm action, with no hint of flex even on slightly stubborn hulls. Each pass of the lever resulted in a consistent, precisely sized hull. I intentionally ran a batch of hulls that were slightly older and had been through multiple reloads, expecting some resistance, but the sizer handled them with ease. There were no surprises or quirks; it simply did its job with quiet efficiency.

Extended Use & Reliability

After several hundred .410 shells have passed through it, the Mec Super Sizer .410 Bore continues to impress with its unwavering reliability. My daily tasks involve processing batches of hulls for upcoming shooting days, and this dedicated sizer has become an indispensable part of that workflow. There are no visible signs of wear and tear; the steel remains smooth, and the action remains as crisp as the day I first installed it.

Maintenance has been minimal, requiring just an occasional wipe-down with a dry cloth and a very light application of lubricant on the press linkage it’s attached to, not directly on the sizer itself. Compared to the generic, multi-caliber dies I’ve used in the past, which often required fiddly adjustments and sometimes resulted in inconsistent sizing, this dedicated .410 sizer truly shines. It has certainly outperformed budget options that tend to flex and wear quickly, and it performs on par with other premium-grade reloading components.

Breaking Down the Features of Mec Super Sizer .410 Bore

Specifications

The Mec Super Sizer .410 Bore is a dedicated resizing die, exclusively designed for the .410 bore shotshell. Its primary function is to return fired plastic or paper hulls to their original diameter, ensuring they will feed and crimp properly for subsequent reloads.

• Type/Color: Sizer only, typically finished in a durable, classic MEC gray or black. This designation means it’s a single-purpose tool, not a combined resizing and decapping unit.
• Size/Finish: Specifically for the .410 bore diameter. This precise calibration is crucial for its effectiveness, ensuring it’s neither too tight nor too loose for this specific gauge.
• Material: Constructed from robust steel. This material choice speaks to its intended use in a high-pressure reloading environment, providing durability and longevity.

These specifications are fundamental to the product’s purpose. The .410 bore specialization means it’s optimized for the unique dimensions of this smaller shotshell, unlike generic dies that might compromise on fit. The steel construction guarantees that it can withstand the significant forces involved in resizing fired hulls without deforming or wearing down prematurely.
