I just went through my first batch of once fired .40 brass, and I ended up putting about 1/3 aside because of damage. Some was gouges in the side of the midsection, some had extractor damage to the rim and the area above the rim. How picky should I be? I reused the ones that had dings and dents, but put aside any that had actual cuts into the case because I assumed that would weaken the brass. I didn't throw any of it away, because I may reconsider using it at a later date. The lengths are not very consistant even among the same manufacturers. Is there a website that would show me what to cull?
