I am going to be buying 500-1000 rounds of .223/5.56 soon and will be looking for an affordable deal for practice ammo. I hear a lot of talk about monarch blue box so I wonder how much it is at academy/walmart (if walmart carries it). I have shot monarch out of my XD before and it hated it but people seem to have good luck with it out of their AR's. So, whats the price on this? Any recommendations on where to get it?
