What causes these? I picked up a bunch of brass at the range yesterday and several of the 45 cases have these. Looks to me like the extractor is out of alignment or bent. But, I have no idea really. Would these cases be safe to reload? My first thought would be yes, the pressure during the next firing will push the dent out. Then I have the thought, that dent has created a weak spot in the case, and the pressure from the next firing may cause the case to fail.
