    I remembered to bring that rcbs tumbler I found at the dump home from my dads. Got me thinking since I have to get some what media do you like and what polish do you use. I've only ever used corncob but the walnut is so cheap. And you can get it anywhere.

    If you would of brought this up before we came to Walton to see you i could of brought you some walnut hull media. My brother bougjt a 25 pound box of coarse walnut hulls from harbor freight.

    I have the same box of walnut hulls and several of the plastic containers of Lyman corn cob media.

    Since I bought the Frankfort wet tumbler i havent used the dry tumbler.
    When I got the wet tumbler I retumbled brass that was dry tumbled and the water came out black.& dirty.

    I use walnut, seems to work just as well as the corncob. Use a dab of brasso and car polish per batch. The brass gets so shiny, I can see my future in it.

    I'd like to do the wet but this rcbs is brand new and free. I'll probably just go to the pet store and for the walnut if I decide on that. I still can't see why someone would throw a brand new tumbler out. Maybe some old guy died.

    For me crushed walnut shells clean faster but corncob media makes the brass nice and shiny. I like both so I use a 50/50 mix and a little polish of some sort now and then. Cut up USED dryer sheets keep the media clean.

    Corncob gets to “dusty” for me, I use crushed walnuts.

    I just get the walnut media from harbor freight, i use the frankford aresenal brass poslish if i have it. If i don't it isn't a huge deal. I do vibratory wet clean them first though - 5 gallon bucket with a lid bungee corded to my lawn mower when i cut the grass, filled with deprimed brass, hottest water i can get , some tide and a little lemi-shine . Don't know if the vibration helps but it doesn't hurt and it's multitasking :thumbdown:.

    What do you do in the winter strap it to the snow blower. I'm not to worried about the shin just cleaning the inside.

    Lol, nope. I either use stuff i cleaned already or i just soak it in the bucket and shake it around every now and then. It keeps media cleaner , just kind of washes the worst of it off before tumbling.

    Depending on the grit I always liked walnut for cleaning the dirtier brass and like corn cob media more for polishing. I add a little Nu Finish car finish with corn cob and get really nice bright brass.

    I prefer Corncob for the wet tumbling-like bling.....(on the outside). I get mine from Zoro....lots for cheap. 20/40 grit so no clogged flash holes. One order lifetime supply for me.

    Takes longer for the mirror finish, but I turn mine on at 8 am and run it all day while I'm at work. I Turn it off when I get home at 5 pm....bling! I use a capfull of Dillon Polish per load.

    1 40lb sack for $33.78 (2 5gal buckets & some change) https://www.zoro.com/zoro-select-blast-media-corn-cob-20-to-40-grit-crn3-40/i/G2165387/
    Oh....I also cut up a couple of used dryer sheets into 1 inch squares and add them to each load....cuts dust quite a bit.

    I use corn cob and Nu Finish. I buy the corn cob by the 40 lb sack. I believe the last I bought was 30-35 bucks and also came from Zorro.

    I use walnut. It gets my cases plenty clean enough for my purposes.

    I use walnut, the corn cob gets stuck in the primer holes. I use Lucas gun metal polish or dillions for the polish.

    ► If you have Prime, then a lot of these medias are available on Amazon with no shipping. Not as good a deal as Zoro.com, but great for sampling different types.

    ► Most of these guys are talking corn cob or walnut. The Reloading Police will not knock on your door if you'd like to mix them. Sometimes you can get the best of both worlds that way.

    Another walnut user here. I've tried corncob, I don't think it did as good a job as walnut. I used Midway brass polish until my stash ran out, now I use Dillon.

    I used to use a half-and-half mix, but the corncob likes to get stuck in the primer holes in .45ACP, so I switched to straight walnut. It takes a little longer to get a nice shine. As our friend Reloadron mentioned above, some NuFinish helps a lot.

    Harbor Freight selks a small pick set for $1.99. It has four small picks, one looks like a small ice pic, one has a 90% bend, one is circular and anither one has a angled bend.
    I use the straight ice pick looking one to get the media out of the flash hole in the primer pockets. I will edit a picture of it when I go up in my gun room.

    Also you will need a plastic bucket and a sifter to seperate the brass from the media. Any of the local grocery store bakerys will have them in the baking dept either for free or for $1.

    Just use the smaller 20/40 mesh corn cob and they will pass through the FP hole. At the same time your buying good quality blast media.

    Wet tumble now, but when I dry tumbled I decided walnut cleaned better and corncob polished better.

    Debated on spending the money for a wet tumbler, I thought how much better can it be?

    Answer is yes it is $150 better.
    A little more work but not that much, you don't have to replace media.
    Does really nice clean brass make ammo that shoots better?
    Probably not, but it makes me smile and I like having clean fingers.

    NO!!!! Brasso uses ammonia. Ammonia weakens brass.

    Like some others, I use half corn cob and half walnut shell.
    A capful of NuFinish every 4-6 loads and two-three used drier sheets, each torn in half.
