The Lyman Pro Dies represent the pinnacle of reloading die performance, crafted to meet the demands of high-volume reloading on Mark 7 presses. These dies are meticulously engineered for optimal functionality and excel not only in progressive presses but also in turret and single station setups.
Constructed from stainless steel, these dies offer exceptional toughness and resistance to corrosion. The sizing dies feature highly polished carbide rings that ensure unparalleled wear resistance while minimizing the force required during sizing operations. Furthermore, each sizing die includes a spring-loaded decapping rod system designed to efficiently eject primers from their pockets with precision.
A highlight of this set is Lyman's renowned M Die neck expander, equipped with a two-step expander plug that provides just the right amount of neck tension and case mouth flare. For pistol reloaders, an additional flare die ensures bullets sit perfectly on the case mouth before seating begins.
Precision enthusiasts will appreciate the Micrometer Seating Die included in each set. This component features a micrometer-adjustable seating head for exact bullet seating lengths. Its floating bullet seating punch centers bullets accurately within cases, eliminating excessive run-out concerns.
Completing this comprehensive package is a taper crimp die which effectively removes any residual case mouth flare while enhancing bullet retention—ensuring every round you produce meets your high standards for consistency and reliability.
