Notice From Hornady: Temporary suspension of nickel plated cartridge cases for Critical Defense® Handgun Ammunition 5/25/21Unfortunately, everyone is faced with production bottlenecks and supply chains are stressed. In particular, the freight system is delayed longer than normal. Our current turnaround time on nickel plating cartridge cases is 4+ weeks. This delay has created a significant bottleneck in the production of ammunition.Due to these issues, we will suspend nickel plating on all Critical Defense handgun ammunition to help reduce production time. We will resume nickel plating when things return to normal.
