FITS: 700UML – This uniquely-sized brass case uses a Remington 9-1/2 magnum rifle primer for ignition. The gas seal is created in the flash hole at the primer. The rifle primer is very hot and cleans the flash hole each time it is fired. Normal barrel cleaning methods will clean the face of the plug and the barrel at the breech. The case is push fed into the breech plug in the same manner a rifle cartridge is pushed into a Model 700 rifle chamber and it is extracted and ejected the same as any Model 700 rifle. The primed brass is packaged in 24 count bags. The cases can be reprimed but should not be used in any other load or application.
