Adding water to the mix makes it less dangerous to handle and allows the mass to be shaped. Even with these precautions, transporting primer mix is hazardous; cartridge cases are moved to the primer chemistry facility rather than moving the primer mix to the case loading location.
To ensure that the mix is uniformly distributed into the hollow rim cavity of the case, both downward and centrifugal force is applied during the spinning operation.
A rotating spinner quill enters each case, causing the case to spin at high speed. The working end of the quill forces the wet mix toward the cavity and the spinning distributes the primer mix to uniformly fill the cavity.
