Currently I'm looking at an ar upper or a bolt gun. Can a 223 be used as a long range round or should I got more for a 30-06/308/22-250 bolt? If I was going bolt I was possibly looking at the 30-06 for its cheapness right now. I know some of you suggest 308 or 22-250 but I'd like to keep the cheapness of the ammo down. Like I said above can this be done with a 223? We'd be looking at a max of 4-500 yards. What would you suggest? Also please include make and model and pic if possible. As for optics I'd guess I'd be looking at mildot recticle or do you suggest something different?
