I'm fortunate enough to get free .223 brass if I pick it up from the range. After washing in soapy water to clean off all the mudd, I have noticed a dent in the middle of the casing on several cases. The dents are from minor to moderate I guess and I was wondering if it is still safe to reload. I guess it is caused by the brass deflectors on the ar's, not for sure though. I would say that about 150 out of the 500 has this dent. What you think? I will be reloading to shoot in another AR.
