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.
Scratches on resized brass

Redding had me polish with 400 grit in a dowel. They said dies are so hard there is very little risk of over polishing them. I.E removing much material when polishing them.
This^^^^^^^^^^^^^^^^^^^^^^^^ and after getting all of the galled brass out of the die, try using the One Shot more evenly, outside the loading blocks. I never spray cases in loading blocks and I don't get difficulty sizing. Improperly applied Hornady One Shot seems to cause more resizing issues than any other type of case lube.
I finally broke down and just use Imperial Resizing wax now. Easy enough to use and goes a long way.
I spray in a tupperware container. I never spray them in loading blocks either. I always see people having problems with it, I don't know how to nail down the cause. It never gives me trouble. Maybe its because I size my brass dirty. {leave on the carbon lube}
after probably 1000 cases run through my die (horndy 6.5cm) this same problem just happened to me. So whats the consensus, polish inside of die?
I polished a bunch of my dies, when I had to polish my redding die. I may just get out some 400grit and polish my Hornady 6.5 Creedmoor die. I have only done about 400 sizing operations with it so far..
I had a set of Hornady 6.5 dies scratch my brass the same way. Bought a new set, and they scratch my brass right out of the box too. Guess I'll try polishing them.
