Supposing a fellow came into the Possession of a DPMS LR - 308 and was wondering what would be a good reasonably priced scope set-up for it. What would you recommend? Also,this fellow has seen 308. Ammo on store shelves and was wondering if the 308 brass is as hard to get as 223 and some of the other. Where would be a good place to find some if this fellow wanted to do some reloading? Just supposing here.
