I will start by apologizing; this has probably been asked before, but I cannot find it.

My tumbler media is toast for my Lyamn 1200 and I was planning on buying more. I was using the light green Lyamn treated corncob media (no dark green). I ahd read that it is much cheaper to just go to a pet store and get lizard bedding which most likely is either corncob or malnut media. The only thing I am wondering about is that Lymna says their medias are treated other than the basic corncob, which is sold that way to allow you to add whatver treatment you desire.

Do you need to treat the lizard bedding? If so, what do you use?

Thanks in adavnce for any helpt you can give me.
 
Add a cap full of liquid car polish (Nufinish, or whatever). Let the machine run for a few minutes to stir it up before you add the brass.
You can also use a bit of jewellers' rouge to help polish the brass.
 
plus 2 on the nufinish. heck you can even add flitz if you want. let it mix up and add your brass.

You can go to princess auto or a welding supply place and grab a 50 pound bag of walnut sandblasting media for a decent price.
 
I buy the 50lbs sacks of crushed walnut shells used for sandblasting from an auto parts store which costs around $35. You can add the above if you want but for the price, I usually just throw it out and replace it with fresh media once it starts to change colour.
 
Meguirs car polish, like cut polish, fine cut cleaner. Has mild abrasives that polish the brass. I started out with a 50/50 blend of green corn cob and crushed walnut that had the jewlers rouge in it (TUFNUT). After about 3000 cases had gone through 700 or so at a time, it started getting dusty and dry so I started adding that polish (about a tablespoon or two) each time I fill it up. I'm now at 7000 rounds of 9mm and stilll using the same media. The added liquid in the polish causes the dust to clump so its easy to remove and the brass looks great! I've even had comments from other people about how nice it looks. If you are shooting straight lead, then I owuldnt keep the media around that long, I use plated so lead contamination is not a concern
 
i use pet store corn cob pet litter,add nu-finish car polish.it works great.once it starts to lose its effectiveness i just add another cap full of polish.throwing some whole/strips of used/new dryer static sheets in the tumbler will help keep your media cleaner/lasting longer.

Ditto. I run my brass for a day in walnut, then a few hours in corncob to get rid of the dust. (That and i run my shop vac and suck up any dust collected when I open the tumbler.)

I can't be bothered f'ing around with it. If it's too dirty, I decant it back into empty 8lb powder kegs.
 
I have just come to the end a batch of Lyman green (treated) corncob so it's now dark green like yours. I'm about to try their restoring liquid for this. A bottle is $4.99 and treats eight pounds, two pounds at a time. (A larger size is also availalbe.) I'll report results when I have them.


... After treatment the media is still a darker green than it was originally, but it is no longer dusty. I put another hundred cases through the treated media and it worked as well and as quickly as when it was new. But I won't know for while how long that will last.
