Calibre Conversions  

 

Pistol conversions 

The calibre conversion for a pistol calibre comprises of 3 basic steps. 

1.

 

Pistol  Shuttle  and  spring  (this  is  the  long  one  installed  in  the 
decapper body as supplied). The shuttle is longer than the rifle and 
has a specific spring. This is used for all pistol cases and can be used 
for the 223 rifle cases as well (Do NOT use it for the 308 rifle cases 
as damage to the machine will occur). 

2.

 

Drop tubes. These are the same as used in the Rollsizer.com range 
of rollsizers. There are different types, (small pistol, large pistol, and 
rifle conversions) 

 

Small pistol drop tube covers 9mm, 38S/SC, 357SIG, 10mm 
357Magnum and 40S&W. 

 

Large Pistol drop tube covers 44Magnum and 45ACP. 

 

Small Rifle covers 300BLK and 223. 

 

Large rifle covers 22-250, 243, 308 etc. 

3.

 

Drop  tube  height.  The  drop  tube  needs  to  be  adjusted  per  the 
photograph below. 

If you have mixed cases (say 380ACP in with 9mm) then adjust the drop 
tube position for the taller of the cases. 

 

Some  cases  will  fall  /  nestle  inside  others  and  cannot  be 
decapped 

together, sorry, we didn’t make the case designs 

so don’t blame us. Examples 

of this include 380ACP, 9mm 

and 38SC inside 40S&W.  For these combinations you MUST 
sort the cases first. 

 

Rifle conversion process 

1.

 

The 223 and 308 cases require a calibre specific rifle drop tubes. 

 

Rifle drop tubes have slots cut in them.  

2.

 

The rifle drop tubes need to be aligned so the cases can be pushed 
out through the slots in the tube.
