Weatherby Unprimed Cases Features The Weatherby Unprimed Cases in .300 PRC are made from quality brass and finished with CNC machined primer pockets held to match grade specifications. That level of machining consistency across every case supports uniform primer seating and more consistent ignition from round to round a detail serious long range handloaders pay close attention to. Because these cases ship unprimed reloaders have full control over primer selection and seating depth from the very first load rather than working around a factory-primed case. Each box contains 50 pieces giving a handloader a solid working batch for load development or a full match day session. As reloading components these cases are not loaded ammunition and are intended strictly for handloaders working up their own .300 PRC recipes. Starting from brass built to the same standards Weatherby applies to its own magnum ammunition gives reloaders a strong repeatable base for developing accurate loads. The .300 PRC cartridge is popular among long range precision shooters and quality brass is one of the biggest factors in extracting consistent accuracy at distance. For handloaders chasing tighter groups and longer case life Weatherby Unprimed Cases are a dependable starting point.
