I've run a lot of ammo through my .25-06 rifle that I loaded from .30-06 brass I picked up at the range. There's concrete around the benches, so when it rolls around and/or gets stepped on it gets scratched up. Unless it's seriously dented or squashed I use it. Always needs trimming after sizing, but otherwise works fine for me.
Like yourself, I figure if it's on the ground it's once fired. A reloader wouldn't let brass go to waste. I grew up with a mother who abhorred waste. Paper plates and paper towels were in tatters before they were discarded. I don't know how many weeks/months I used the same plastic bag for my sandwich in my lunch box. Apple don't fall far from the tree.
