Bullet Seating Die 
At the top of the press stroke, the bullet will be seated 
into the case. Bullet seating depth is controlled by 
adjusting the Seat Plug Stop (A) up or down. Shorter 
length cases may be accommodated by moving the 
Retaining Ring to a higher groove on the free floating 
bullet Seat Plug (B) (see Photo 16). However, larger 
diameter bullets may not drop into position if the Seat 
Plug (B) is hanging too low. This is a trial and error 
adjustment. 
Seat plug bushing has approximately 0.5” total 
adjustment.

For cartridge lengths greater than 2.5”, raise the Bullet 
Seat Die Assy up so that the lower part of the window
