The Sinclair 8000 Series Uniformers are precision ground from one solid
piece of tungsten carbide, so there is no need to worry about changing the
depth of cut. These cutters will cut the primer pocket to a uniform depth
and also square the bottom of the pocket in relationship to the case head.
Uniformers are available in five sizes, one for large rifle, small rifle and/or
small pistol, large pistol primer pockets, PPC/BR primer pockets, and BMG
