More lube and polish the inside of your de-capping die.

A few additional suggestions:

1) Try Horndady One Shot spray lube - I have had better success with it then any others I have tried to this point...
2a) Double check to make sure that your shellholder is clean and that the round is able to get fully pushed in before re-sizing.
2b) Even if it is clean, make sure the round is always pushed completely into the shellholder. I have noticed that if it isn't, scraping of the coating occurs...

I used to have the problem you described to some extent, but now that I have been following the above steps I only round into that problem a few times per thousand...

Any tips on polishing the die? Dremel?

Try my suggestion above first (if you want) and see if it solves your problem (it did for me...)

Then, if you need to still, you can get cotton polishing heads for the dremel and they also make red polishing compound - you would want to make sure that the polishing head fits nicely into the die (just snug but not too tight..) Most likely it will be too big when you get it, so you can take box cutter or other really sharp knife and shave it down when its spinning (be careful/cautious of course) until it gets to just the right size. Make sure you polish evenly, dont let it sit in one place for too long. I would polish it for about a minute, re-apply the polishing compound and repeat 3-4 times, by then it should be looking really good...

Hello - New here

Found this forum by this thread. Got interested in 5.7X28 in a roundabout fashion. Wanted to build cheap 22lr bullpup - found P90 airsoft conversions - found 5.7X28.

I have read this entire thread and have an idea to make resizing easier and improve case life.

My idea is a flameless neck annealer. The flame test mentioned would indicate that the critical part of the case could be annealed without damaging the coating. This would make resetting the shoulder position easier on both the die and the brass.

After reading this thread I compared some of the once fired brass I obtained with a new Federal AE5728A round - wow!

I will be building one for my own use - am wondering if there would be an interest in this group for more of them.

Cartridge Case Coating

Post by klw » 05 Oct 2015, 14:04

Anyone ever figure out how to repair or replace the original coating?

Failing that it would be nice to see a list of things that have been tried even if they failed.

lacker

Post by klw » 15 Nov 2015, 15:09

I assume that no one has figured out how to replace the lacker, or whatever it is, on the cases.
But it would be interesting to know what people have tried in an attempt to do this.
