I have been reloading for about 50 years.
This makes me "experienced". it does not make me an "expert"! This fact was brought to the forefront again today as I was working at the bench, resizing mixed headstamp 223/5.56 cases. I, like most serious reloading "loonies", pick up range brass and eventually sort and process that brass. As I reached the bottom of the can, maybe 5 or six cases left, I ran a case through my, 1976 dated, RCBS 223 dies (I have several sets of 223 dies, neck sizers and dies set to load match cases and sets set up to load for my heavy barreled Savage and HB 700 Rem.) and as I examined the case after removal I noticed that there were scratches on the case from contamination. (probably fine sand, as much of the brass I prick up comes from non formal range shooting spots on the desert) I removed the die and while making comments that will not be repeated here, cleaned the dies and reinserted the die into the press. Sized another case and checked it. Rats! still showing scratches! This is not my first experience with damaged dies. I have scratched several carbide 38/357 dies (again from contaminated/dirty cases. Yes, carbide dies can be damaged! At one time I had three or 4 damaged dies that I have damaged myself or picked up on the cheap from people who had done the same thing and just bought another set because they were told there was no way to fix them.)

Several years ago I had an epiphany. I stumbled onto a way to repair the damaged dies, at home, with just the tools that the average person would have in the shop or garage. I took some jeweler's rouge and mixed it with some CLP and made a soupy paste. I applied this to a worn and dirty bore mop, chucked it into a drill(I used a small drill press but you could do it with a hand drill also) and inserted the mop into the die, from the bottom and polished the inside of the die. Removed and cleaned the inside and tried the die on another case. Waalaa, scratches gone! I got the aforementioned 223 die on the first try but carbide dies usually take more than one application as the carbide is so much harder but it does work.

I am sure that to the many experience reloaders, this tip is old news(or they have found an even better way, Please feel free to let us all know) but maybe it will help out some of the folks that are new to the hobby. And the problem wouldn't have happened if I had washed the cases (as I usually do) instead of being lazy.

I did the same thing with a 38 die..............

was going to ship it back to RCBS for a free polish or die but
tried some Fitz on a mop first and I was a happy camper.

Good enough for my needs......
but I do make sure my brass is clean now before sizing.
They don't ALL go right to the ammo box on the family outings, if you catch my drift.
 
I appreciate you fellows telling us your experiences. There have been others who have pooh-poohed the idea of dirty brass scoring the wall of a die, but you have provided sufficient testimony to convince me to continue to tumble my brass. Thank you.

I scratched a RCBS carbide die. I gave RCBS a call. Their suggestion was to wrap some 600 grit sandpaper around a dowel, chuck it in a drill and polish the die. Works great. I've repeated it a couple of times since.
 
HINTS

This is a hint to be remembered- :) THANKS!! Brings to mind, some years ago when I was getting a LOT of brass from the H&K range a few miles away. At one point I scratched a 45ACP carbide die. All brass had been cleaned so the only conclusion I could come to was the primers that had not been removed- :( since that time I recap ALL brass before cleaning, & polishing. No, media in the flash hole is not a problem as it is removed when brass is resized. :) Never could figure out why this was a problem for some. I just never figured carbide dies could be repaired. They were Lee dies so sending back somewhere would not have been cost effective. A short time later in getting ready to retire I up graded to all REDDING dies so if such a beast should rear it's ugly head again I will be ready.:D THANKS AGAIN!!
 
Thanks for the tip. I was one of the doubters, but I'm glad to know the damage can be fixed.
 
I have used Clover Compound 800 grit for this job.
As mentioned before, primers are a likely culprit.
Have read that some may contain ground glass.

I have some of those as well- not sure of grit, maybe 600- know I gave several away to a local custom gunsmith. There are some. new to me,gun cleaning swabs I have tried and really like, I am betting they would do and work fine for such a job. Mine are in 45ACP and work GREAT. Gettig ready to order some off Amazon in357/9mm. :)

Am thinking they would work to polish some cylinders as well, such as .22LR :)
 
Does it affect the quality or performance of the round, or are we just talking cosmetics of the round?

If only cosmetics, does it really make a difference if the case is scratched or not?
 
After each season of 5.56 brass-resizing, I run a bronze brush on a power drill into the neck of the die, and have at it for a couple minutes. Swab it then with Break-Free. Put die away until next season.

All my brass gets tumbled in walnut shells before sizing.
 
Sure an easy fix, but the question is why are you putting dirty brass into your dies??? A min would be to wash them in warm/soapy water. Dry tumbling better still & wet tumbling being the ultimate in clean. Clean your brass BEFORE it ever sees the inside of your sizing die. If you want to deprime, then get a dedicated decapping die.

No but your ammo looks like krap.

If the scratch is deep enough it will be the beginning of a failure point of the case.
