Norma Dedicated Components Unprimed Brass for the .338 Norma Magnum delivers reloadable cartridge cases engineered for precision handloading and extreme long range applications. Manufactured in Sweden to tight dimensional tolerances, these cases feature uniform internal volume, consistent case wall thickness, and factory-annealed necks and shoulders. Designed to hold heavy .338-calibre match and hunting projectiles within standard magazine lengths, each case uses a standard Large Rifle Magnum primer pocket with a drilled flash hole and pre-chamfered case mouth for uniform bullet seating.

Key Features

• Consistent Internal Volume: Precision-drawn brass walls ensure uniform case capacity across the entire batch for repeatable internal ballistics and velocity consistency.
• Factory-Annealed Necks: Controlled neck and shoulder annealing provides optimal elasticity to extend case life and reduce the risk of neck splitting under pressures up to standard CIP and SAAMI limits (approx. 64,000 psi).
• Pre-Chamfered Mouths: Prepared case mouths streamline initial bullet seating during load development and handloading workflows.
• Magazine-Optimised Geometry: Engineered specifically to chamber in .338 Norma Magnum rifles, allowing long, high-BC bullets to seat without intruding excessively into usable powder capacity.

Who is the Norma .338 Norma Magnum Unprimed Brass for?

• Extreme Long Range (ELR) target shooters — provides uniform internal case capacity across a 50 Pack of unprimed rifle brass cartridge cases to maintain tight extreme spread (ES) and standard deviation (SD) for precision engagements at 1,500 to 2,000+ metres.
• Tactical and military-style long-range platform shooters — accommodates heavy 300-grain .338-calibre match bullets within standard tactical magazines using dedicated .338 Norma Magnum cartridge case dimensions.
• Long-range big game hunters — utilizes factory-annealed necks and Large Rifle Magnum primer pockets in a 50 Pack of brass cases to ensure reliable ignition and extended case life during high-pressure load development.

Less suitable for: Handloaders seeking brass for rifles chambered in .338 Lapua Magnum, .338 Winchester Magnum, or standard magnum bolt-face calibres; choose calibre-specific cartridge brass matching those chamber and bolt-face dimensions.
