Build the perfect load has long been the motto of handloaders loyal to Nosler brand bullets–and was the sole reason we developed Nosler cartridge brass. Introduced in 2005, the Nosler cartridge brass line is ready to load. Manufactured with the traditional Nosler philosophy of uncompromising attention to detail, Nosler cartridge brass is created to exact dimensional standards and tolerances, using quality materials for maximum accuracy and consistency potential while extending case life. Nosler brass also undergoes the rigorous quality control that premium Nosler bullets have experienced for over 70 years.
