CH4D Blank dies for 9mm Luger

Blank Crimp Dies will put a perfect six segment rose - crimp on virtually any case. Straight walled cartridges require only the blank crimping die but on most rimless calibers (i.e. 9mm, 45 ACP, etc.) it is necessary to put a shoulder on the case to control head spacing. Therefore, blank crimp sets include a blank crimp die and a shoulder die.

Substituting blanks for live ammo in automatics will not function the weapon unless it is modified, probably making it unusable for real ammo.
