I've been considering adding a 7.62x51 rifle to my firearm portfolio. Right now it's between the FAL and M1A. Before I make my purchase, I'm trying to find out the best place to purchase bulk ammo, as well as how much it will cost per 1000 rounds. I've found milsurp (Radway Green) and new stuff (ATI) for around $400/1000rds. Is this typical, or are there better deals out there?
