I looked seriously at the .223 when I got my .22-250, but IMHO the 2 bucks more a box for .22-250 Rem or Hornady is well worth a faster bullet, flatter trajectory and more energy. And, I'm not made out of money. Besides, I don't shoot FMJ in any of my rifles for safety reasons, and that's why I don't buy Mil Surp ammo. Hearing them whine away off into the distance makes me nervous.
