Our 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. (the 5 in 1 set also includes a trim die).
CH4D was formed in 1990 when CH Tool & Die and 4D Custom Die Co. merged. This merger combined the standard caliber product line and 5 decades of industry experience from CH with the hard to find product list and short run production know how of 4D, to create what we believe is the highest quality line of reloading gear and to be found in the world today.
Substituting blanks for live ammo in automatics will not function the weapon unless it is modified, probably making it unusable for real ammo.
