Any .223 bolt that DOESN'T make 200y shots...well, you know where I'm going. SHoNuff, the more I thought about the more I'd lean towards 7mm-08. That 7mm is going to be alot more forgiving in the wind and with the right rifle itself will determine how accurate it is. I'd find a rifle cheap enough you can then afford real good glass and even action bedding, pillar stock etc. for the accuracy side of things.
