Primer Tools - Paper Punch 4mm Rotary

The rotary preference is mine (I like to have options) but the accepted standard is 4mm. It (the diameter) will split the rim of the small primer cup in half (OD=0.175x). I was mistaken in an earlier video about the dimensions of the small rifle/pistol cups. The ODs of the small pistol/rifle/hard rifle is the exact same (within specs) but the IDs are different (thickness =0.017", 0.020", 0.024" respectively). I'll be discussing the anvils in another video.
