Can't be the first guy to do this....

....sigh.....

Tumbled some brass that was still damp on the inside, now I got this corncob goop inside 100 338 cases. They're not full, just some kernels sticking to the inside, mostly inside the shoulder, and a thin layer of muck everywhere else.
Any suggestions? Tumble again? Ultrasonic? Dental pick and a couple hours?

 

[JohnnyPython]

Tumble again no pins.

Before you tumble, maybe leave them in the sun and shake as much of the dry crud out.

 

[Ganderite]

I switched from corn cob to the fine ground walnut media that Princess Auto sells. About $30 for a huge bag. I like it because it is so fine it does not stick in primer flash holes.

You cruddy ones should dry out and then tumble again. They should come out clean.

Don't have a SS tumbler. They are very dry.

Tumble in corncob or wait until I pick up some walnut?

 

[JohnnyPython]

Sorry, I misunderstood. Thought you wet tumbled and didn't dry the cases completely.

Try dry tumbling the cases again.

Why were the cases that damp, did you wash them in something first?

Leave them in the sun for a couple day's, mouth up

Have the same problem, especially on the 223 case, hope the ( fine walnut media works). Its not the initial cleaning, its the second pass of tumbling ( deprimed already/ resized and taking out the lube). btw, any suggestion how to take out the lube without tumbling?, hate those media getting stuck in the case. thanks

Learn something new everyday! I am gunna grab some of this stuff at that price!

Yes, washed to rinse the lube off.

1-Use Lee lube because it doesn't contaminate smokeless powder;
2-Don't tumble the cases after depriming/resizing, tumble the ammos after they're loaded.

I use Lyman quick slick spray, it's water soluble so a quick rinse cleans it off.

I tumble after sizing to take the lube off. An hour in the fine walnut media does it. Longer if the brass is not very clean to start with.

Sometimes, when in a long loading session, I load the lubed brass and then tumble the loaded ammo. That is so I don't lose any time waiting for the sized brass to be available to prime and load.

 

[Chilly807]

I'm not saying this is correct, but I was told that tumbling loaded rounds can have the effect of reducing powder kernel size and therefore changing burn rate.
Any thoughts on that?
It'd be interesting to pull bullets from tumbled loaded rounds and compare powder kernels.
I don't tumble my brass, I'm simply curious.

 

[Leatherstocking]

I use walnut, then compressed air to blow out any media left. Air might work for you if available..
As for tumbling loaded rounds, someone did extensive testing, concluded, no problem. IIRC he tumbled loaded rounds for 200 hrs, then examined powder with a microscope.
Google it.

You'd need a lot more force to break down kernel then what a tumbler generates inside the case. If that was true, a 16 hours airplane ride from Canada to Kaboul and then an 8 hours truck ride would have the same effect.

 

[Alpheus]

I remember seeing photos where a guy tumbled some 9mm and 223 for like 200 hours and then examined the kernels under a microscope. No discernible change.

I'm using my home brew of Lanolin and Alchohol combo, just wondering how easy is it to rinse Lanolin with Dawn and warm water. , Now the drying is the next problem, Sorry gents just getting old, lol

I do most of my reloading in winter, and to dry my brass after cleaning, I put it all in an old fry basket (french fries, etc) and place the basket over a floor vent. Furnace comes on, hot air blasts out of the vent, and I stir the brass for a few minutes. It gets quite hot, and dries the brass just fine.

OK, up the down staircase... If the amount of crud isn't too bad and the primer pockets aren't plugged, then go ahead and load them per normal with a not-too-hot load. The crud will be gone next go-round and you will have learned something.
