Lapua Unprimed Cases Features Lapua Unprimed Cases in .300 WSM are manufactured from brass using advanced metallurgical research and precision manufacturing techniques that keep dimensions consistent across multiple reloading cycles. The .300 WSM cartridge itself offers meaningful advantages over legacy belted magnum designs including a shorter bolt throw and reduced overall weight which enhance handling during a hunt or a long day on the firing line. Each case is built to be reloaded again and again without losing the tight tolerances handloaders depend on for repeatable accuracy. This makes the .300 WSM an efficient short action option for hunters who want big cartridge performance from a compact platform. Each box contains 100 unprimed cases sized for large rifle primers ready for a handloader s own primer powder and bullet selection. These cases are intended strictly for reloading and are not loaded ammunition giving experienced handloaders full control over their load development. The base body and neck sections are engineered to hold tight tolerances and maintain reliable primer pocket tension even after repeated firing and resizing. For rifle shooters chasing the tightest most consistent groups from their .300 WSM rifle Lapua brass remains a trusted foundation for serious load development.
