just long enough to remove lube.. 20 minutes maybe..
no need to tumble ammo loaded with a carbide die..

Found the thread for you where Walkalong and snuffy, after 48 hours of vibratory tumbling newly loaded rounds, examined the powders for break down, measured the OALs and ranged tested with chronos. Results - No break down of powder, no reduction of OALs and no change to muzzle velocities/SD - http://www.thehighroad.org/showthread.php?p=6210466#post6210466ljnowell said:Here we go again. There is a thread right here on THR where two members took loaded rounds and tumbled them for two days! Thats 48 hours. There was no degredation of the powder at all and all rounds shot just as expected.
I think this myth may have come from someone tumbling old/surplus ammo to clean/polish the brass case where the powder has started to break down or already broke down and saw that tumbling made it worse. I would not tumble old/ammo (just hand wipe clean/polish) but would not hesitate to tumble newly loaded rounds.This is a myth that the powder will break down. That powder goes through a lot worse being on trucks and whatnot as its shipped around the country.
The powder could get shipped around the world 100 times on a wagon and I don't think it would come close to 48hrs in a tumbler.That powder goes through a lot worse being on trucks and whatnot as its shipped around the country.
I don't do it because it seems like a waste of time. Sorta like lubing cases that get resized in carbide dies.
I don't. I do very, very little shooting of bottle-necked rifle cartridges. When I do, I wipe it off. When I load for the .32-20 and .38-40, I apply a light film of gun oil before sizing and wipe it off afterwards.Curious how you remove case lube? If you have a faster way than a tumbler I would love to hear it.

Powder manufacturers strongly recommend against it as it will break down the powder and change the burn rate.

Depends on how many cases you have to do, but for me it's usually faster to hand tumble them around in a cake pan lined with paper towels doused in denatured alcohol. 10-20 seconds of this removes 90% of the case lube that I use. All the powder blackened lube comes off, and the cases are shiny and non greasy (enough) to the touch.Curious how you remove case lube?

I rinse mine in a bowl with some white gas AKA naptha in it. It evaporates quickly and whats left is returned to the can.
Just wanted to know if you leave them sitting around for a while do they tarnish?
Rusty, The question possed by you in your post #34 was how does one remove lube, I answered that question in my post #42 by rinising in white gas.
From that point on was not addressed by your question.
Actually I do then tumble the cases in 20/40 Corn Cob media from DrillSpot with Auto Cleaning Polish added. Currently I happen to be using a can of paste Mcguiars I no longer use on my car. I do not wish to have all the lube in my media. No, I have no problem with tarnish.
