So I ordered 1000 rounds from another post. Spoke with seller today who advised that when they came in, he thought they were reloads. He called manufacturer who advised its all new brass, up to LC spec but manufactuer isn't equiped to polish casings before assembly. Has anybody heard/seen this before? Any problems with using unpolished casings in gun e.g. Feed problems, etc? This is probably a dumb question, but can you run live rounds through a tumbler to polish casings after they are already assembled? My gut reaction is this is probably not a good idea but figured I'd throw it out there. Any advice is appreciated. Thanks.
