Lapua .300 PRC unprimed brass gives precision handloaders a consistent foundation for building ammunition for rifles chambered in .300 Precision Rifle Cartridge. This package contains 100 new cartridge cases intended for carefully developed long-range target and hunting loads. The .300 PRC uses a modern beltless case configuration designed to accommodate long, heavy .308-inch bullets with high ballistic coefficients, making the cartridge a practical choice for shooters who want to tailor ammunition to a specific rifle, projectile and application. Lapua manufactures its rifle cases from selected raw materials and controls the production process to maintain close dimensional tolerances. The case bases are made hard and resilient to help them retain their shape through repeated loading cycles, while the necks are formed symmetrically and annealed. The annealing discoloration that may remain around the neck and shoulder is a normal result of this manufacturing step rather than a cosmetic defect. Consistent case geometry is particularly useful when preparing matched batches, establishing repeatable neck tension and developing loads where small variations can affect performance at extended distances. These cases are supplied unprimed and unloaded, allowing the reloader to select the appropriate primer, powder charge and bullet for the rifle and intended purpose. They are not complete ammunition and require proper case inspection, preparation and loading with suitable equipment and published load data. Because component dimensions and internal capacity can vary between brass manufacturers and production lots, established loads should be reduced and worked up again when changing to these Lapua cases. For shooters assembling precision .300 PRC ammunition, this 100-count package provides a uniform supply of reloadable cases for methodical load development, competition practice or customized hunting loads.Specifications and Features: .300 PRC unprimed rifle cartridge cases 100-count package Beltless case configuration 7.62 mm (.308 caliber) case family Annealed, symmetrical case necks Hard, resilient case bases Designed for precision handloading and repeated reloading Brand: Lapua Product Type: Unprimed Rifle Brass Manufacturer Part Number: 4PH7098C UPC: 6418267200875
