I have always in the past picked up brass at the range. Over the years I have accumulated a buch to reload. Recently I picked up a bunch of .308 empties. Reloaded them and they are real crap. Brass is super soft, rims under size that tear off on extraction, primer pockets so soft the primers fall out after shooting. I'n done picking up range brass, I hope. Now I have to sort through a bunch of reloads to find them, pull down and scrap.
