Nosler Brass is 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 60 years. Same quality you’ve come to expect from Nosler Custom brass, but may need some prep work before loading. This brass is new and unprimed. This is not loaded ammunition.
