Uniforming your primer pockets is the most important operation you can do to your brass.

• The way brass is made will have your primer pockets dish-shaped, they will also vary in depth, this causes your primer to seat at different depths.
• If the firing pin strike varies from shot to shot, it will result in varied powder ignition and produce inconsistent pressures and velocities. As a result, you can expect to see vertical shot dispersion which is when shots are strung up and down the target.
• Our KCP Custom Carbide Primer Pocket Cutter Uniformers are ground from one solid piece of oftungsten carbide so there is no worrying about changing the depth of cut.
• Our KCP Custom Carbide Primer Pocket Cutter Uniformers will cut the primer pocket to a correct and uniform depth, will square the bottom of the pocket in relation to the case or the head.
• Our KCP Custom Carbide Primer Pocket Cutter Uniformers can be used with the optional KCP Universal Handle, or with the KCP Custom Power Adaptor in a drill or power screwdriver, or they may be used in the drill or power screwdriver without the adaptor.
• Dan uses the KCP Custom Carbide Primer Pocket Cutter Uniformers each time he re-loads. As you fire cases, residue from the primer and brass will flow into the primer pockets, you really need to clean out this residue each time you re-load.
