Key Specifications

• Expander-Decapping Unit built into the sizer die removes the spent primer and expands the neck to accept a new bullet in one pass.
• Vented die body releases trapped air and excess lubricant so cases don’t dent or stick during sizing.
• Minimum headspace tolerances held by the sizer die keep the case body length consistent, load after load.
• Seater Die with Bullet Seater Plug seats the bullet straight and to the correct depth.
