Cleaning Brass

[Fishseeker]

As I am just getting into reloading while spending time in the book reading I have also been cleaning brass, my question is should the inside look like the outside or am I being to picky, after 9 hrs I changed the media as it looked really dirty then 3 more hrs with clean media and the insides are 80 to 90% clean, is this normal or should I keep at it.

don't worry about the inside at all. If you are so anal that you feel it must be clean, get an ultrasonic cleaner.

that is normal. i have never seen anybody so rich as to throw away polishing media after 1 use before though.

Thanks guys.

No I did not toss it is saved I will use it to start a batch then use some cleaner stuff to finish.

Nine hours? Man, just pour in a cap full of NuFinish car polish and tumble for half that!

Inside needs to be free of debris, that's all. Outside doesn't really need to be super-shiny either, but it's nice.

I've only been reading the Lyman so far, but aren't tumblers exactly for that purpose?

Brass doesn't have to be clean on the inside. However, if you have a tumbler and use fine grit walnut media then it seems to do half decent job cleaning the inside.

I would imagine that if you get much buildup and crud inside the brass then that could impact charge density a little bit. Could give you inconsistent accuracy if you're in a competition.

Nine hours? how many shells did you have in the tumbler? 3? Dude you need to load it up with a couple of hundred and all you need is an hour or so.

One hour with a capful of Dillon rapid polish/walnut media and the brass looks really good. With the noise my monster Dillon Magnum FL-2000 makes, even that seems like a long time.

I used to do a second corn media tumble, I dont anymore...clean is good enough...they dont need to be trophy polished.

Ceramic porcelain polishing media gets some great results in a short time too.
