Lightning Ammo Primed Brass Features These Lightning Ammo Primed Brass Rifle Cartridge Cases for .338 Lapua Magnum are manufactured in the U.S.A. by Vairog USA giving reloaders a domestically produced brass option for this demanding magnum cartridge. Arriving already primed with Federal number 215 Large Rifle Magnum primers the cases eliminate one step from the reloading process letting shooters move straight to powder charging and bullet seating. This is especially useful for reloaders working with .338 Lapua Magnum where consistent ignition from a reliable magnum primer matters for extreme long-range accuracy. Starting from quality primed brass also reduces the equipment and time investment needed to begin loading this cartridge. The cases are packaged in quantities of 50 inside MTM Case-Gard ammo boxes which protect the brass during storage and transport while keeping it organized by count. It is important to note that this product is unloaded component brass and not finished ready-to-fire ammunition. Reloaders must still charge seat and crimp these cases to complete a cartridge. For .338 Lapua Magnum shooters looking to streamline their reloading workflow these primed cases from Lightning Ammo offer a dependable starting point.
