5.56 x 45 (5.56 NATO)
Brass: New or Reman (choose below)
*IMPORTANT: Though both cartridges look identical, 5.56 is loaded to a higher pressure than .223, which is why rifles chambered for a 5.56 cartridge can fire .223, but it is not recommended that 5.56 cartridges are fired out of a rifle chambered for .223

Shipped and delivered in same week. I shot 100 rounds of this 556 target ammo. It was mostly Lake City brass with only a couple other head stamps. Everything fired and cycled perfectly. No malfunctions at all. Was very accurate. Best 10 shot group was under 1.5", take out the 2 fliers and the other 8 were sub moa. I'll definitely buy more in the future.
75 rounds at 100 yards SanTan Tactical build
I bought some 77gr SMK 5.56 ammo from Haywood at the Dulles Expo center last weekend. Today, I went to Elite Shooting Sports to break-in my new build. The build is a SanTan Tactical billet receiver set. It has a Ballistic Advantage Hanson 5.56 1:7 14.5 Barrel, BCM Flash Hider, FailZero BCG and Trigger, BCM Butt, Leupold Mark AR Mod 1 1.5-4 x 20 Firedot scope. This ammo is the truth!!!! I strongly urge everybody to put this against all other brands. You will not find a better accuracy.
556 frangible arrived in a timely fashion and operated perfectly as you can see
Indoor ranges sometimes can’t handle 556, so this 556 frangible was perfect. Thank you for quick shipment and a great product.
