    Great 5.56 brass.

    Lake City is great brass. Very consistent weight for the price. I use it in my gas and bolt guns with great results. To the other reviewer giving a poor review for the brass being 1.740 in length, that is perfectly fine. Nothing bad can happen from that. That's what mine measured and it quickly grew to 1.750 upon first firing and FL resizing.

    Good brass

    Federal has always made their brass shorter than any other maker. It should not present a problem unless you are already using a compressed load. It lasts as well or better than most

    Brass too short

    Bought 1000rds of this brass. All of was 1.740 in length. That is 10 under ALL of the reload manuals trim to length. Called Federal and stayed on hold for as hour and a half. Was told too bad that's how we do ours. Buyer beware!!!

    Decent brass for the money

    Seems to be as effective as other brass. Unsure of longevity as yet. Much better than Winchester so far.
