    I have a bear creek arsenal upper in 223 wild with a 20inch SS slick side charge and man I'm telling you that this stuff shoots 5 shots into 1/2 inch groups all day long, I bought this ammo because it shoots as flat as a 22,250 55 grain bullets do, I've yet to shoot any yotees yet but when I do you guys will be the first to know, I can't wait!!!!!

    Zero issue with this rounds performance, even with my limited rifle experience I was able to get 1 MOA accuracy out of my AR15 style rifle.

    Very reliable ammo and consistent. A little on the pricey side but you get Hornady quality.
