I can recommend this guy: http://www.ammoman.com/index.htm I've ordered from him before, ammo came in a nondescript box (except for the typical ORM-D markings) and everything turned out great. His prices for 5.45 seem pretty good. Generally speaking, I'm surprised at how much cheaper it is than 5.56. I mean I understand why, and especially cause of ammo quality but, still I just always seem to have this assumption that rifle ammo always has to be pretty expensive. Hell, I wish I could get 1000rd cases of 45acp that cheap!
