It's possible to use a Lee collet die on cartridges other than the one for with they're designed. This is useful when Lee does not make a collet die for the case you want to reload.
The technique may involve putting a shimming washer around the case after it's inserted into the shell holder on the ram.
For example, I'm using the collet die for the 22 Hornet on 218 Bee cases. The length from the base of the case to the bottom of the neck is about 0.07 inches longer on the Bee than the Hornet. So the Bee case is put into the shell holder, a washer a bit thicker than 0.07 inches is dropped over the case, and the press operated to squeeze the neck of the case against the mandrel.
