The Bullet Specific Seater Stems are not for use with the Simple Seater.

Choosing a stem specifically for the bullet you plan to use will eliminate marking the ogive of the bullet and minimize variation in seating depth. When ordering additional stems for your Whidden Gunworks Dies, if you are unsure of the correct length for your specific caliber, please reference the stem that was included with your dies and order the same length.

WHEN ORDERING PLEASE E-MAIL US AT [email protected] WITH CARTRIDGE CALIBRE REQUIRED 

Whidden Gunworks has now developed a system to match our seater stem shape exactly to the bullets handloaders are using. Our Seating Dies include a seating stem that we’ve designed to work well with a wide range of bullets. However there is now a chance to optimize bullet seating and eliminate marking the bullets while seating through the use of our bullet specific seater stems.
