Getting rid of the media dust. How?


March 4, 2010, 04:16 PM
Hey Guys

I get my brass used and like to:

1-Tumble them to get them a little clean before using the sizer/deprimer on them;
2- Size/Deprime all of them and start cleaning the primer pockets;

I Noticed that i can't get rid of all the dust from the media from inside the cases.
Will that affect the powder in any way or do i have to wash the cases BEFORE priming them?
Some people advise me against washing the cases at all but if i don't, how do get rid of the dust?

Thanks again guys!

I use a liquid cleaner (Flitz) to treat the corn cob when tumbling brass. In addition, I get a dryer sheet from the laundry room and cut it into small squares. By treating the corn cob media and using the dryer sheet, I have eliminated almost completely any dust from the tumbling.

Polish helps, but I also sprinkle in some water when it starts getting dusty. That fixes it if the media has any life left.

Also using WAY to much polish will cause a dusty problem.

Try using fabric softener sheets cut into small squares, used ones work the best, 'cause the new ones have too much moisture. replace them as they become laden with dust. If you still have too much dust you can use a nylon bristle brush for cleaning kits,and brush the dust out, but this adds another step in the reloading process.

I hvae never had a problem leaving the dust, but it could become a problem if it started to turn to hard ash like deposits. If you wash the cases get somthing on the order of denatured alcohol, you can use the type used to thin laquer it is 100% and evaporates quickly.

A little dust left inside the cases doesn't hurt a thing.

Use the dryer sheet to pick up excess dust in the media and you won't have enough dust to worry about it.

Dryer sheets, lizard litter, and fine rubbing compound.

Midway sell an RCBS media separator with a built in cover. I wish they offered these when I started reloading.

spread the media out on a window screen and shake around to filter the fines through may take a couple-3 'whacks' with palm to break up congestion.
dump onto newspaper to fold then dump back into tumbler.

Take the tumbler outside, run it without the lid on, and without any brass in the media, and the wind will blow the dust away.

I don't worry about the inside of the case--I let the powder take care of that.
I use ground walnut from RCBS or Midway--clean case enuf to resize ( keep cover on)then I have a steel rod cut down to fit tight inside case & run it in a drill press--shine with steel wool--- looks great .................
