    300 AAC BLACKOUT FROM WINCHESTER BRASS

    Excellent quality and consistency! .......And shipping was very fast.


    Cases were very clean and shiny, both inside and out. The only possible improvement would be to chamfer the inside of the case mouths, but having converted MANY 5.56 cases to 300 AAC myself, I know that a separate operation would be needed for that. (....Which would add to the production costs.)


    I will be buying more as soon as they are back in stock.
