Custom bullet seating stem. Hornady manufacturing offers the advantage of making custom dies to your specifications. These custom-manufactured dies are available in either our custom-grade or match-grade die configuration, and can be made to load any cartridge. Replace the bullet seating stem made to fit any bullet of any profile, lead or jacketed. These precision dies give the handloader total control over the loading process. These seating stems are designed to fit Hornady Custom Grade Dies and are machined to fit the profile of the A-MAX, A-Tip, ELD Match, ELD-X, FTX and MonoFlex bullets to seat them as precisely as possible without damaging bullets. (Not compatible with other manufacturers' dies.)
