The Mighty Armory 38 special, 357 magnum bullet seating die will seat bullet diameters from 38 caliber including .357, .358, .359, .400, .401, .402., 10mm. In addition, the 38 special, 357 magnum seating die will cross over to seat the 40 S&W, 41 caliber, 10mm.
Mighty Armory’s bullet seating die captures the bullet head, holding it vertically to set the bullet into the case smoothly and concentrically, ensuring precise cartridge overall lengths (COLs).
Suitable for coated, plated, full metal jacket, hollow point, personal defense bullets, and more, the Mighty Armory seating die performs exceptionally. Its precision-machined steel bullet barrel eliminates case bulge, prevents bullet scarring, and enhances the consistency and reliability of your ammunition.
Unlike seating dies that use a stem, which can scar the bullet tip and affect accuracy, the Mighty Armory bullet bore holds the bullet perfectly vertical and unscathed, improving bullet coefficient and performance.
The adjustable seating die is easy to set up: place your bullet on the flared case and adjust the die up or down to achieve your desired COL.
The design also folds back the case flare 80% and sets the bullet tension pre-crimp, resulting in perfectly concentric SAAMI spec rounds with increased accuracy every time you load.
