About Lyman Pro 4-Die Set

Under the expert craftsmanship of Lyman, the 223 Pro 4-Die Reloading Set emerges as the pinnacle of reloading precision and durability. This set is meticulously designed to meet the high-volume demands of Mark 7 presses, yet its versatility shines through as it delivers exceptional performance in standard progressive, turret, and single station presses alike.

Crafted from robust stainless steel, the size, seat, and crimp dies boast superior toughness and are impervious to corrosion, ensuring a rust-free experience that extends the life of your equipment. The sizing dies feature highly polished carbide rings, renowned for their wear resistance and ability to reduce sizing force, making your reloading process smoother and more efficient.

The innovative spring-loaded decapping rod system within the sizing dies guarantees a forceful ejection of the primer from the primer pocket every time, enhancing the reliability of your reloading routine. Rifle cartridge reloaders will appreciate the inclusion of Lyman's acclaimed M die neck expander, with its two-step expander plug that provides optimal neck tension and case mouth flare for improved accuracy.

For pistol cartridge reloading, the set includes a specialized flare die, designed to ensure bullets are perfectly seated on the case mouth prior to seating. The precision-engineered Micrometer Seating die features an adjustable seating head for meticulous control over bullet seating length, while its floating bullet seating punch expertly centers the bullet on the case, minimizing run-out.

Each set is completed with a taper crimp die, meticulously designed to eliminate any case mouth flare and enhance bullet retention, giving you the confidence that your ammunition is secure and ready for use. The Pro Series Micrometer Taper Crimp Die, with its adjustable micrometer head, allows for precise crimp adjustments, ensuring consistency across your reloads.

The Two-Step Neck-Expanding (M) Die is an indispensable tool for those using cast or flat-base bullets, as it does not stretch cases like standard expanders and thus extends case life. The die's expander plug has two steps: the first expands the case neck to just under bullet diameter for precise tension, while the second expands the case mouth to bullet diameter or slightly over, allowing for a perfectly centered bullet start.

Lyman's 223 Pro 4-Die Reloading Set is not just a testament to high-quality reloading equipment; it is a commitment to providing reloaders with a professional, reliable, and sturdy toolset that enhances their craft. With more features at a competitive value, this set stands as a top choice for serious reloaders seeking to elevate their ammunition reloading capabilities.
