Guys

Today is my dads Bday, and I just got him a brand new remington model 700 the new synthetic ugly stock, in a 223 remington. He has a scope for it (3x9) leupold sittin in the safe, and the bases. My question is, what is the best factory ammo out there for it? We dont reload, and i would like something for 5-7 dollars a box that can actually make good groupings. Any thoughts fellas?
