    FWIW; This debate has been going on as long as I have been visiting reloading forums, mebbe 15 years. Some say no, don't tumble as the powder breaks down and pressures go up. Some say yeah do it, factory ammo is tumbled/vibrated. But, in all the time I have been reading about this I have read no factual evidence of the powder breaking down, and never read of a live round discharging in a tumbler or vibrator, never. I have read of tests done where a batch of ammo was loaded and some were fired and chronographed and results recorded. A few hours of vibrating and another test firing. The a few days of tumbling and a test firing. No difference in chrono readings. A round from the control group was disassembled and a round from the last tumbled group was disassembled and the powder compared under a microscope; no difference. I haven't been as exact in my reporting this test as I read it and it was long enough ago that you may take it with a grain of salt.

    I would like to see a test done in a lab, but so far it hasn't been done or reported. Until then, I would tumble and vibrate loaded rounds if I had a need...

    I would echo what dagger dog said about wiping them down. I think you are very unlikely to see a detonation but, to me, it is more mess than it is worth. I suffer from OCD, however and can't stand seeing finger prints or, heaven forbid, lube streaks on my loads. I have taken to using a rag damp with prolix or alcohol. I know there are a lot of folks who would criticize using prolix but I have never seen it do anything but shine them up and it doesn't break down under heat. More than anything, it is probably just a waist of $$.

    I tumble after to remove lube.

    Done it with 1000's of dirty surplus over the years also.

    Wiping them down would work....but when I am making 100's at a time, that isn't happening.

    Of course the manufacturers are going to say don't tumble, they have to protect themselves from any liability. Folks do dumb things, and when those dumb things backfire they hire lawyers.

    I wear rubber gloves ALL the time from the time it comes out if the tumbler. I don't like to touch anything that I am loading as I don't know how long it will sit as a loaded round or tumbled case. The only rounds I touch with bare skin are the ones I'm using for that hunting season and the ones im loading I shoot.

    I've heard you can tumble but if you do for too longs some theorize it could make your powder break/ powder up down and change the burn rate! Personally I wouldn't.
