The Lapua 6mm BR Norma Brass is the benchmark reloading case for benchrest and precision rifle competitors, long considered the gold standard against which all other 6mm BR brass is measured. It features a small rifle primer pocket and Lapua's signature hard case head construction, maintaining consistent dimensions and holding primers tight through dozens of reloading cycles. The properly annealed neck and shoulder ensure consistent neck tension and long case life whether using full-length or neck sizing, and strict concentricity and wall thickness tolerances deliver the round-to-round consistency that hundredths-of-an-inch accuracy demands. Packaged 100 per box, this is the brass that serious benchrest and long-range competitors have trusted for decades. Lapua 6mm BR Norma Brass Box of 100 4PH6046C
