Hi Guys -
I know the standard media for tumbling brass is either walnut or corncob, but has anyone ever tried using blasting media?
I've got about 500 lbs of a coal slag blasting media called black magnum (black beauty is the same stuff). Its a fairly small grit size. I use it for sandblasting my restoration project. It breaks down as I use it. I usually get about 2-3 sprayings with the same material before it breaks down to a point where it isn't aggressive enough for steel.
Would this work for tumbling brass (assumings its been screened to get the crap out of it) or would it still be to aggressive and wreck the brass.
What do you guys think?
Joe

I've done quite a bit of sandblasting with the same stuff and I think it would leave too much residue on your cases. Try getting it out of your ears and nose, it may be almost as much fun fishing it out of primer pockets and flash holes!
Try it with a small batch of junk brass and see what happens (and throw a dryer sheet in the tumbler for good measure).

I haven't tried it yet. At this time, I don't have any used media, as I haven't done any blasting for a while.
I found a reference that the IK headstamped (ingman) 5.56 brass has that other primer (berdan or something like that) so I won't be able to reload it. So, as soon as I get some used media, these will be my test subjects.

I don't think using blasting media is a good idea.
Unless you take extreme care to remove even the finest residue from the cases, your dies are likely to suffer from accelerated wear & scratches.
That's the beauty of walnut & corncob - they can't damage either your brass or your dies.

I am interested in the results you might get with sandblasting media. It might be useful in cleaning some of the heavily stained 223 cases I have.
After I used the blasting media I think I would use some corn cob to clean up afterward.

I would say dont do it, it's not worth the risk!
You can screw up your brass, your dies and imagine fire lapping your barrel every time you pull that trigger, just more risk than potential for gain.
If you have cases that are badly tarnished just hand polish them with scotch brite or steel wool before tumbling.

I tried polishing them with steel wool with cases chucked up in my Makita cordless drill but it was just to much work for the thousands of cases I need to clean.

You know that a nice shiny finish is what we all would love to have, but sometimes it's not achievable, and it really doesn't make ammo shoot one bit better.
I do mine in walnut hull with a little brass polish added, if badly tarnished I'll put them on tonight and remove them tomorrow evening. Any spots that remain will just have to stay.
I did experiment with some garnet in my tumbler once and it gave my cases a dull sheen that never polished away. I got to thinking about what we used that stuff for and then spent a long while just making sure it was all removed from my thumbler bowl. It's the media that we use in our water jet cutting machine, it'll rip a 1"ss plate in half in just a few mins.

I am not a fanatic about shiny brass but this stuff looks pretty bad. With the price of brass what it is now I think this stuff would warrant spending a few bucks on. I have about 2 1/2 gallons of brass range pickups once fired Lake City 06.

72, Just add a tablespoon of Flitz to your media and they'll come out looking pretty good. Or I you really can't stand the look of them I'll help aleve that stress by taking them off your hands. I just shoot a Savage and it's not high falutin' enough to care.  RD

I'll be shooting the them in one of my two ARs or my Model 70 Heavy Varmint. Nothing that is falutin at all.

Many years ago I used a liquid cleaner that I simply soaked my brass in, and it seems that it did a great job of brightening the dull cases. I don't remember what the name was but I do remember why I got a tumbler and stopped using it, a hassle to get the cases dried out. I had to spread them out on a cookie sheet and place them in the oven for a while.

I have always heard that Flitz chemically attacks the brass and makes it weak and brittle. I was told never use Flitz on shell casings ever.
Regarding blasting grit, what do you think it will do to the interior of your tumbler? No thanks. I've had plenty of lightly chocolate brass load just fine after a pass in the walnut.

I tried black rock polishing compound once. Scratched the hell out of the cases. Go buy bird litter at the pest store. CRUSHED WALNUT. Why put abrassives on your brass the will ruin your reloading dies and chamber.

The only blasting media I use is corn blast.
Graingers sell it.

Ain't no way I'd put my brass in any kind of abrasive grit and then shoot it's dust down my bores.
Shiney cases are totally meaningless. We can get them plenty clean by sloshing them around in moderately soapy water in a kitchen sink or even a bucket for a few minutes.

hmm from a consumer standpoint let's see ...100 clean shiny cases vs. 100 grungy or darkened cases ..same money which would u buy ?
from a shooter and consumer standpoint ..two rounds both full length sized..same height same bullet same brass same powder charge etc ,one clean and shiny one darker which one would i put in my dear to my heart most accurate varmit rig ?
both scenario's no toss up -even a non reloader and inexperienced shooter will grab the shiny object first lolz
i hate it even when my rifle brass hits the dirt

I cleaned around 150 IMI 223 cases that been outdoors for about a year, heavily tarnished with corn cob and brass polish from Franklin Aresnal for about two or three hours. Did a great job. Took out tarnish, cobwebs and whatever.

I grit balst, bead blast and sand blast as well blasting with walnut shells. The best thing to tumble your dirt cases in is walnut shells with some Flitz. It worked for me for many years, never found a problem with this combination.
