Walnut media now sticking inside cases - thoughts ?

(1/2) > >>

Larry.K:
Hello to all, this is my first posting.  I've been reloading for last couple of years, using Frankford Arsenal tumbler and ground walnut media from local pet store.  For the first time ever, now about a dozen or so small media granules are sticking (like static electricity?) inside the various cases, have never had this problem before.  I don't introduce any kind of cleaner or liquid into the media nor use any cloth or dryer sheets, and this instance occurred on the 2nd tumble of newly poured media when I changed out the old media.  Nothing different about temp or humidity where I do my hobbying.  Its remotely possible the cases may have had some minute dampness as I went from a very cold range a week or so ago, to my cold trunk ride home and then right into the tumbler upon arrival.  Even if I give the brass a sharp tap on something, it does not dislodge the remaining clinging media bits.  Anybody seen this before and have any thoughts on how to proceed?

Just outa curiousity.........

If you do happen to have what seems to be a static electricity problem,

Why not try dryer sheets???

And see if doing so reduces/eliminates the problem.

Probably won't hurt the media or the cartridge cases.

Chances are, the new media is considerably drier than the old stuff, therefore more susceptible to static electricity.

Use a pointy tool to reach some of the stuck media and try to move it.

If the media simply moves and sticks to a different place, then appears to be a static issue and laying the brass on a grounded surface should remove the surface charge and allow the media to drop away.

If the media is dislodged and falls out of place, most likely moisture from condensation of the cold brass caused media to stick and all will need to be phsically removed. Maybe as simple as de-prime, wash in soapy water and rinse then air dry or bake in a low oven temp. Future loads, let the brass get to room temp and dry (since it might get condensation from warming up) before tumbling.

For my cleaning, I wash range brass (as some of it might be quite dirty. Then de-cap with a Lee universal de-cap. Run the brass through a rock tumbler with stainless steel pins with a couple teaspoons of Dawn detergent, a couple .45 cases full of Lemi-Shine (another dish cleaning product) and water. The cases are pretty well cleaned and even the primer pockets get reasonble clean (better than tumble cleaning and de-cap or can be cleaner with longer run in the pins). Cases tumble for 30 to 45 minutes and are rinsed and set out to dry. The brass is more of a satin finish than a polish, but feed/fire just fine. Advantage is eliminating the dust from dry tumbling...some really nasty stuff is released in the dust.  Have read accounts of lead contamination in work areas and even blood levels of people handling dry tumble materials.

Adding cut up dryer sheets will remove static and dust from your tumbling media.

Just a note, it's also winter time... central heat will remove moisture from the air, increasing static problems all across the board.  Have this problem at work (embedded computer stuffs), and have noted it at home with powder sticking to drop tubes etc.
