A buck a round? Hard to believe that kind of price for 223/5.56 ammo. Is that for military ball? I remember buying UMC ball in the yellow box for like 2.99/20, back when I had a 223 model 70 about 25 years ago, That was one of the attractions of a 223 vs a 22-250 or something like that-- cheap surplus ammo. How times have changed.
