So before I get land blasted for what sounds like a very novice problem, I have been reloading for over 30 years and this is the first time I've encountered this issue. In short, I resized 100 pieces of once fired 6.5CM brass with brand new Hornady dies....no issues. Then the next batch I start to resize, from the first piece of brass, I noticed difficulty running the brass through the resizing die. On inspection there are several scratches running the length of the brass (vertical of course). Prior to trying to resize the brass was cleaned in a wet tumbler with only solution and no pins, dried, then placed in reloading blocks and sprayed with a light coat of One Shot. After seeing a few pieces come out scratched I removed the die and can see brassy colored stripes running vertically inside the die. I disassembled the die and tried to clean it out with Bore Tech Eliminator and can still see the brassy scratches. Then I resorted to a chamber mop in the drill with Wheeler 600 lapping compound... I can still see and feel the scratches. I'm getting the feeling that this die may be trashed. Any input is appreciated.
