The secret to perfect alignment is holding the bullet case and seating stem in the same close fitting chamber for the entire seating operation. Both the bullet and the entire case are held in perfect alignment while the bullet is seated. 

Features :
• Innovative caliber-specific Die Chamber holds the case the bullet and the seating stem all in perfect alignment; supporting the entire outside diameter of the sized case rather than just the bullet and case neck. (Most competitor products support only the case rim.)
• Non-crimping style provides accuracy consistency and perfect alignment. (Exception; 30-30 caliber die does crimp.)
• Seating stems match your special bullet needs such as those encountered during the loading of most VLD (Very Low Drag) bullets on the market.
• Micrometer version available with ultra accurate seating depth adjustment.
