“The” Seating Die 

Why does Short Action Customs make a bullet seating die?

We make a bullet seating die because like you, we are passionate about precision shooting and reloading. Much like our ground breaking bullet jump research we believe in challenging the status quo, we believe in thinking differently.

This obsession has lead us to these questions:

  • Why do I need a bullet seating die for each cartridge that I shoot?

  • How does a bullet seating die affect cartridge neck and bullet runout?

  • Why do I have to modify or buy custom bullet seating stems to prevent damage to my bullet?

The Bullet Seating Die is designed to be the only bullet seating die you will ever need for a family of cartridge bodies. For example, with out purchasing any additional parts, you can easily and precisely seat bullets in any cartridge body which has a base diameter (.200″ above the bolt face) of .470″ to .473″ in diameter.  That is virtually every short action, standard bolt face cartridge!!!

Here is how The Bullet Seating Die works. The center bore of the die body is drilled and bored to ensure concentricity and parallelism to the bottom of the die and 7/8 x 14 threads. Next we precision ream the center bore for a perfect finish, lastly the hole is internally burnished for a mirror like surface finish while controlling the inside diameter to a tolerance of +/-.0002″.  This precision guide channel only has .001″ to .002″ total clearance around the base of the cartridge, properly locating the cartridge in the die body.

Next the spring loaded Cartridge Shoulder Sleeve and precision guided Bullet Seating Sleeve are held concentric and are guided by this precision cartridge bore in the die body. This ensures the absolute most concentric and true assembly.

Furthermore, we top off The Bullet Seating Die with a Mitutoyo Micrometer head which has .001″ graduations for a total travel of .500″ for the more precise bullet seating adjustments. Lastly, we incorporated a micrometer tension system to achieve a very positive feel when turning the micrometer head and prevent accidental movement.

The Bullet Seating Die can properly seat 22 cal, 6mm, 25 cal, 6.5mm, 7mm, and 30 caliber bullets!

Bullet Seating Stems

Model 1: Works best with 22 cal to 6.5mm bullets. *** As of 10/28/2020, we updated the Model 1 bullet seating stem to have a “Tapered Funnel” at the mouth to prevent any damage to bullet tips due to the larger flat face on the previous Model 1 seating stem. Model 1 seating stems shipped out after September 1, 2020 which have a nominal body diameter of .346” only apply. See pictures below to identify a Model 1 stem that can benefit from this upgrade.

Model 2: Works best with 6.5mm to 30 cal bullets. We have seated 6mm bullets with the Model 2 with no issues.
