I got in contact with Tier-One-Armoury today and grabbed a couple cases of Black Hills ammo. I wanted to snatch up a supply of ammo before it was all gone, and who knows how long it will be before we see this stuff again. I tried the 77 gr .223 and it shoots like a hot damn, through both my ACR and my AR. The 168 gr .308 is as good as, or better than my FGMM for group size and feels a little hotter in the shoulder. It was a cold day at the range, and I forgot my camera, but I'll have to put up a detailed review on the ammo soon.
