Really? I was told a long time ago to use about a tablespoon so that’s what I’ve done.

Yes, really.

Just buy some PPU or MENS ammo. They shine the brass cases somehow.

PPU 17

I don’t know about 50, but Ive ran .223, and .308 in a tumbler overnight in walnut media with a little bit of brasso and a couple used dryer sheets and they turned out great.
Dump the brasso! It contains ammonia which causes embrittlement and cracking of brass. Try Flitz.

As to tumbling loaded ammo, you are not "supposed to." However, if you use a plastic chamber (Folger's Coffee plastic container) in a rotary tumbler, fill it with media so that the movement of the rounds is limited. The risk of a primer being struck with sufficient force to detonate it is virtually impossible. The easily burstable plastic container is a second safeguard.

I have never used a vibratory tumbler so cannot render an opinion there. Maybe SAAMI would have some direction in that regard. There used to a a national reloading manufacturers' association, but it seems to have gone defunct.

I don't see a tumbler generating anywhere near the force that a firing pin does. Also, outside a chamber, even a 50 BMG isn't going to send a projectile flying across the room. It might shoot the brass a few feet, and would probably do some damage to the tumbler, but that's all I would expect. But of course you should use your own judgement. FWIW, I've had live ammo make it into the tumbler a couple of times and nothing happened after hours of tumbling.

Tumbling live loaded ammo....... jeez. :rolleyes:
Do you reload? Everyone I know who reloads always does this to remove the lube used during the reloading process. I respect your opinion but see a tendency to always have the “ONLY RIGHT” opinion. This applies to all subjects you get involved in, even glocks, lol. I’m not starting something here, just have been observing for quite some time now and notice things.

Am talking about firing and resizing the cases. Brittle brass leads to neck and body splits. The Brits found out the hard way that ammonia attacks brass.

This is the first I've heard of it. NOBODY I know tumbles after loading. If you have that much lube left over, perhaps less lube is in order. A quick wipe with a paper towel takes care of any excess I've encountered.
FWIW, I haven't had any problems caused by tumbling loaded ammo, mind I've only been doing it ~30 years.

I’m not the only one here advising against it. And yup, I state my opinions, just like everyone else.
 
Interesting reading here, arguments for both sides in the comments:

 
I thought this comment from Hodgdon was interesting:

It is the policy of Hodgdon Powder Co. to recommend against ever tumbling or vibrating loaded or reloaded ammunition. Vibration for even short
periods of time may degrade propellants or change their burn characteristics. Vibrating propellants may cause coatings to wear off and edges or
ends to erode.

This from RCBS too, page 2 of their Vibratory Case Polisher manual:

DANGER! DO NOT TUMBLE/CLEAN CARTRIDGE CASES OR AMMUNITION CONTAINING LIVE PRIMERS AND/OR POWDER. The vibrating action of the Case Polisher can break down the structure of the powder kernels and priming mix. This may lead to an unsafe ignition of the cartridge or possible misfire.




From the horse's mouth, not too sure how anyone can argue this with more than "I've been doing it for years".

Never thought of that. Makes a lot of sense.
