Good evening, fellow Air Warriors. Your friendly [highlight]gun nut[/highlight] here with some information some of y'all may be interested in. What I am providing a link to is The Ammo Oracle. Everything you'd ever want to know about the .223 Remington/5.56x45mm cartridge. Read up. Some of you could use it, some of you I know are interested, and Marines, you guys will probably get a kick out of it.
