Buy Once-Fired Brass 308 Winchester Grade 1 Bag of 500. This is mixed headstamp once-fired brass that has been picked up from military, law enforcement or public ranges. Minor dings and dents or slight imperfections may result from this environment, but most flaws can be easily removed upon resizing or will be “shot out” upon first firing. Grade 1 Brass has been cleaned, polished, deprimed and the military primer crimp removed (if applicable). This is not loaded ammunition. Note: This 308 Winchesters brass is military brass and may have been fired in a belt-fed, fully-automatic firearm. Because of this, you will need a die set capable of returning the brass to true SAAMI dimensions. We recommend the RCBS Small Base 2-Die Set, Product # 681-255 or Sizing Die (Only) Product # 597-261.
