CH/4D 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.
