Since most of the ranges in the North DFW area only seem to allow brass? HP or SP for AR15 range ammo, what do y'all who don't reload, prefer to use? I'm looking around trying to find a decent price on relatively clean factory ammo, but am not having the best luck. I don't want to run dirty or bad quality ammo, but I don't want to run the high quality 1 dollar ppr stuff through it for range practice either. Trying to find a nice balance and would really appreciate some opinions from others in the same boat.
