Most manufacturers punch the primer pocket into cartridge case head;
Therefore all cases do not have equally deep primer pockets, and the bottom usually has a radius. This causes the primers to be seated unevenly and to different depths;
It could cause some primers to protrude from the rear of the case, which is dangerous because it could cause a slam fire;
Primers should be seated to 4 Thou, or 0.1mm, below the surface of the case head;
For safety and uniform ignition it is strongly advised that the primer pockets be cut to the same depth;
This is done with the MAMBA primer pocket uniformer.

Primer detonation leaves a burnt residue at the bottom of the primer pocket;
Removal is necessary to ensure that a new primer is mounted correctly and equally deep;
It is important to make sure the cleaner does not fit too stiff and possibly damages the sidewalls of the primer pocket;
Be careful to use it in such a fashion to only remove the residue at the bottom of the pocket without damaging the case material.
