MEC Outdoors 8452 600 Jr. Mark V Die Set 28 Gauge Reloading Dies

The MEC Outdoors 8452 600 Jr. Mark V Die Set delivers precision reloading capabilities specifically engineered for 28 gauge shotshells. This complete die set transforms standard components into consistent, accurate ammunition while reducing per-round costs significantly compared to factory shells.

What Makes This Different

Unlike generic reloading dies, the Mark V design incorporates MEC's proven geometry that ensures consistent crimp formation and proper hull resizing with each cycle. The precision-machined steel construction maintains tolerances within 0.002 inches, delivering factory-level consistency shot after shot. These dies work exclusively with MEC 600 Jr. progressive reloaders, creating a seamless integration that eliminates common alignment issues found with universal die sets.

Key Features

• Precision-machined steel construction for consistent shell dimensions
• Mark V crimp design creates uniform star crimp closure
• Compatible exclusively with MEC 600 Jr. progressive reloaders
• Hardened steel surfaces resist wear after thousands of cycles
• 28 gauge specific sizing ensures proper hull reformation
• Complete die set includes sizing, wad guide, and crimp dies
• Factory-calibrated spacing eliminates setup guesswork

Field testing demonstrates these dies maintain shot pattern consistency within 2% variation across multiple reloads of the same hull. The Mark V crimp design prevents gas leakage that can reduce velocity and accuracy, particularly important for competitive clay shooting where consistent performance matters. Hunters appreciate the ability to create custom loads tailored to specific game and shooting conditions while maintaining the reliability needed for critical shots.
