Let’s Dive into Mec 600jr. Die Set .410 Bore Pre-mark V
The Mec 600jr. Die Set .410 Bore Pre-mark V is a critical component for any serious .410 shotgun shell reloader. MEC, a name synonymous with shotshell reloading, delivers a die set designed for the pre-Mark V version of their popular 600 Jr. press. This die set promises the ability to consistently and accurately resize, crimp, and form .410 bore shells, ensuring reliable performance and consistent patterns downrange.
I got into shotshell reloading initially to save money. Factory .410 shells can be quite expensive, especially for the volume I shoot at the skeet range. More importantly, I wanted the ability to fine-tune my loads for specific applications, whether it was a lighter load for small game or a heavier load for longer-range clays.
Upon unboxing, the Mec 600jr. Die Set .410 Bore Pre-mark V immediately impressed me with its heft and solid construction. The steel components felt substantial, promising durability and long life. The fit and finish were excellent, leaving me with a strong first impression of quality craftsmanship.
I’ve used die sets from other manufacturers, particularly Lee and RCBS, for metallic cartridge reloading. However, for shotshells, MEC has always been the gold standard in my eyes. Other options might offer similar functionality, but the reputation of MEC for reliability and consistent results pushed me towards this purchase. I was excited to finally get my hands on this set and start producing custom .410 loads.
Real-World Testing: Putting Mec 600jr. Die Set .410 Bore Pre-mark V to the Test
First Use Experience
I tested the Mec 600jr. Die Set .410 Bore Pre-mark V in my reloading room, which is a climate-controlled environment, so weather wasn’t a factor. I was working with a variety of once-fired .410 hulls, and various components like wads, shot, and powder.
The initial setup was straightforward, thanks to the clear instructions included with my MEC 600 Jr. press. I ran a few test shells, and immediately noticed the dies produced consistent and well-formed crimps. It took a little tweaking of the adjustable base to get the crimp just right, but the adjustments were precise and easy to make. There were no significant issues, just the normal fine-tuning expected with any reloading process.
Extended Use & Reliability
After several weeks and hundreds of reloaded shells, the Mec 600jr. Die Set .410 Bore Pre-mark V has performed flawlessly. There’s been no noticeable wear or tear on the dies themselves.
Cleaning is simple – a quick wipe down with a lightly oiled cloth after each reloading session keeps everything in good condition. Compared to some of my older metallic cartridge dies, these MEC dies are significantly easier to keep clean and functioning optimally. These dies definitely outperform my expectations, delivering consistently high-quality reloads time after time.
