Hornady Seater Die for Custom Grade Series III 2-Die Rifle Set 5.45X39 (.221)

The Hornady Seater Die for Custom Grade Series III 2-Die Rifle Set in 5.45x39 (.221) is a precision reloading die engineered for shooters who demand consistent bullet seating and superior accuracy. Built using CNC-machined construction with extremely close tolerances, this seater die gives reloaders fine control over the ammunition-manufacturing process—critical when working with military cartridges where consistency directly impacts downrange performance.

The die features a floating bullet alignment sleeve and stem designed to center the bullet and case before seating, preventing misalignment defects that degrade accuracy. This alignment mechanism is particularly valuable when loading 5.45x39 ammunition, a cartridge known for tight case tolerances. The Custom Grade construction ensures repeatability across hundreds of reloading cycles, maintaining die concentricity and dimensional stability that mass-produced dies cannot match. For the serious 5.45x39 reloader, die quality directly correlates to group tightness and velocity consistency.

This seater die serves shooters who reload surplus or military-pattern 5.45x39 ammunition for precision rifle work, competition training, or high-volume range sessions. Whether working with steel-cased or brass-cased 5.45x39 cartridges, the floating-sleeve design accommodates dimensional variation inherent in military ammunition runs while maintaining centering. The die integrates into a standard two-die set configuration, making it compatible with most single-stage and progressive reloading presses using standard toolhead mounting.
