Fire about a 1000 rounds in Ruger 556 without any problems. For me, this is some accuracy clean brass casing 223 ammo out there. I would definitely buy again at this price.
This is my favorite .223 brass casing ammo for the price. If you are looking for cheaper .223 ammo, take a look at the Tula or Wolf 223 ammo. A little dirty, but you get what you paid for.
