The Peterson 400 Legend Brass Rifle Casings offer shooters premium, match-grade brass engineered specifically for the .400 Legend cartridge. Made in the USA from high-quality brass, these cases feature a straight-walled, rebated-rim design that aligns with the .400 Legend’s SAAMI dimensions, including a small-rifle primer pocket for compatibility with standard small-rifle primers. Whether you're loading for hunting or target work, the uniform wall thickness, precise dimensions, and consistent manufacturing process provide a strong foundation for reliable, accurate ammunition. Sold in a convenient 50-piece box, this offering is ideal for reloaders building small batches, testing loads, or stocking quality brass for future use.
