If the range brass looks like it's once fired (rifle) and not berdan primed it goes home with me. Pistol stuff as long as the case mouth doesn't have more than a 90 degree bend in it I'll shoot it until it wears out. More than a 90degree sharp bend in the case mouth usually will crack within a reload or two for me. The dark brown stuff included as long as there's no bubbly looking corrosion areas. I've been reloading some 45acp over and over again that I got back in the 80's. Rifle brass 30-06/308/556 generally I won't get fully bright and shiny the first couple times through the wet tumbler. Probably could easy enough but it doesn't bother me to use rescue brass.
