Dual Ring Carbide Sizing Dies - Dual Ring Carbide Sizing Die, .40 S&W

These tool steel sizing dies incorporate two separate Titanium carbide rings to properly resize straight-wall pistol cases. With a single stroke of the press, the top ring dimensionally sizes the case at the mouth, while the lower rings sizes the length of the case body without overworking the brass and shortening case life.
