WARNING!  Avoid loading shorter than the minimum length.  This will seat the bullet deeper into the 
case.  This decreases the case volume and increases the pressure, which could lead to an overpressure 
condition especially in pistol cartridges due to their smaller internal volume.

 

                                                
 

8.5.2

 

Installation and Adjustment of the Pistol Seating Die--Determine the overall length required in your reloading 
manual--write it down.  Again, loading manuals provide the COAL based on SAAMI (Sporting Arms and 
Ammunition Manufacturers’ Institute) standards.  The cartridge overall length specified in the reloading manuals for 
a cartridge is usually the minimum length for that bullet/powder charge combination.   

•

 

The Dillon Pistol Seating Die has a removable double-ended Seating Stem.  One end is for flat nose 
bullets and the other for round nose bullets.  There is another Stem for “wadcutter” bullets for 38/357 
only. 

•

 

Select the Seating Stem that matches the nose of the bullet being seated.  Assemble the Seating Die as 
shown below.  This design allows for quick cleaning of these items without losing the adjustment. 

 

 

•

 

Screw the Seating Die down in Station 3 until the bottom of the Die is flush with the bottom of the 
Toolhead.  At this point, the Die will not be down far enough to begin seating the bullet.  Place a belled 
case into Station 3.   Place a bullet on the belled case mouth and lower the Handle.  Then, raise the 
Handle.  Remove the Cartridge and use a dial caliper to measure the overall length of the cartridge 
(COAL).  If the bullet is not seated deep enough, screw the Seating Die down 1/2 turn at a time.  As a 
guide, one full turn moves the Die about .070”, about the thickness of a nickel.  Replace the cartridge in 
Station 3 and repeat these steps until the correct overall length is achieved.  (A quick method for pre-
setting the Die is to place a previously loaded “good” cartridge in the seating station and adjust the Die 
down until it touches the bullet.)  Tighten the Die Lock ring with a 1” Dillon Bench Wrench while 
holding the Die with a 7/8” end wrench with the Platform up (Handle Down) and a cartridge in the Die.

Installation and Adjustment of the Bottleneck (Rifle) Seating Die with Adjustable Seating Stem— 

•

 

Check the overall length required in your reloading manual.   Again, loading manuals provide the COAL based 
on SAAMI (Sporting Arms and Ammunition Manufacturers’ Institute) standards.  The cartridge overall length 
specified in the reloading manuals for a cartridge is usually the minimum length for that bullet/powder charge 
combination.   

•

 

It is a good idea to chamfer the inside of the neck on a bottleneck/rifle cartridge before the bullet seating step.  
This helps the bullet get started into the case and minimizes damage/scratching of expensive precision bullets.  
Chamfering is easily accomplished with a chamfer tool such as the Wilson Deburring Tool available from 
Dillon—PN16038.  This tool can deburr the inside as well as the outside neck of the case.
