These tough, oversized cases will accommodate virtually any combination of two or three Forster dies including the longer Ultra Micrometer dies. In addition to all standard calibers, the new boxes are also large enough for dies in the new extra-long Ultra Mag calibers. The deluxe die boxes incorporate blow molded, double-wall construction, a process that provides a layer of air to protect the dies during shipment and from accidental dropping at the reloading bench. The boxes measure 8-1/2" X 5-1/2" X 2-1/2". The larger size also means that once reloaders have found their ideal setting, the dies can be safely stored in the box without fear of losing that perfect setting.
