## Peterson .338 Lapua Magnum Unprimed Brass (50)

Peterson .338 Lapua Magnum Unprimed Brass (50) is unprimed, Match-Grade brass manufactured by Peterson Cartridge in Pennsylvania, USA. A premier extreme long-range and military sniper cartridge, the .338 Lapua Magnum is built for exceptional accuracy and retained energy well beyond 1,000 yards. Every casing is produced on Peterson's state-of-the-art, automated production lines and passes through 100% inspection to ensure structural consistency from case to case — minimising the variables that can affect accuracy and helping you get more reloads per casing than the industry average.

-   **Match-Grade Quality:** Manufactured to Peterson's Match-Grade standard, with consistent dimensions, weight, and neck tension from casing to casing.
-   **100% Inspected:** Every casing produced passes through automated and hand-inspection processes to confirm it meets Peterson's quality standards before packaging.
-   **EZ-Seat Coating & Anti-Tarnish Finish:** Peterson's proprietary EZ-seat coating promotes consistent, uniform bullet and primer seating on first load, alongside an anti-tarnish finish for long shelf life.
-   **Annealed for Consistent Neck Tension:** Each casing is annealed during manufacturing to relieve material stress and deliver reliable, repeatable neck tension across reloads.
-   **LRP Primer Pocket:** This casing uses the standard Large Rifle Primer pocket and flash hole configuration.
-   **Made in the USA:** Manufactured at Peterson Cartridge's production facility in Pennsylvania, USA, using domestically and internationally sourced raw materials.
-   **Unprimed, Box of 50:** Supplied unprimed and ready for reloading — not loaded ammunition. Packaged in a 50-count box.
