Just be careful. Tumbling loaded rounds is not recommended. It can cause the powder in the case to break down / degrade and burn faster than intended.Wet tumble with stainless chips. I'll occasionally dry tumble loaded rounds, usually cast stuff to clean some of the lube off

Do you have a reliable source to substantiate that statement or is it an internet myth? Here is one source that says it’s a myth.Just be careful. Tumbling loaded rounds is not recommended. It can cause the powder in the case to break down / degrade and burn faster than intended.
Both the chief ballistician for Hornady and hodgdon say that's false. I'm pretty sure there are some manufacturers that tumble loaded roundsBy vibrating the case in the tumbler it vibrates the powder in the case as well. Dust comes off the media because it abbraids itself, even if you run it with no brass. Thus the powder can abraid itself in the case as well

If that’s so, why does powder in bottles and jugs, or for that matter in commercial ammunition, not destructively abrade itself as it rides from factories to distributors to store shelves to end users? Not to mention military and law enforcement vehicles and helicopters.By vibrating the case in the tumbler it vibrates the powder in the case as well.

Riding in a vehicle, in a box, which minimizes vibration, is not the same as deliberately putting it in a confined space that vigorously vibrates with the intent of abrading things.If that’s so, why does powder in bottles and jugs, or for that matter in commercial ammunition, not destructively abrade itself as it rides from factories to distributors to store shelves to end users?

Again I ask, do you have a legitimate source for your assertion or just internet myth?

No one is claiming that abrasion doesn't take place. Of course it does. But, you stated in post #3 that tumbling can degrade powder to the point of affecting it's burn rate. I gave you a reference in post #5 in which 2 legitimate sources, the Chief Ballistic Scientist at Hornady Manufacturing and the Head Ballistician at Hodgdon Powder, both agree that what you stated in post #3 is a myth. I've simply been asking you to cite any legitimate sources who support the myth and can back it up.Riding in a vehicle, in a box, which minimizes vibration, is not the same as deliberately putting it in a confined space that vigorously vibrates with the intent of abrading things.
do you have any legitimate sources which disprove basic physics that vibration does not cause materials to abrade each other?
And I have stated basic science supports it, which you agreed with. Powder being abraded increases the surface area and thus will effect the burn rate. Now, will it be to a degree that effects the over all performance or makes things unsafe. That depends on the duration and speed/frequency of the vibration. Vibratory tumblers are aggressive in relation to the speed and frequency of the vibration, the only control one has is the duration. While the effect may be minimal if the duration is short, it will have an effect, the only question is to what degree.No one is claiming that abrasion doesn't take place. Of course it does.

I absolutely agree that basic science supports that abrasion takes place when two surfaces rub together. But, it does not support the internet myth that tumbling affects burn rate. If you will take the time to read the article that I linked to in post #5, you will see that the deterrent which controls burn rate is impregnated into the powder grains, not just on the surface. It can't be rubbed off. Without any legitimate sources that say otherwise, which you have yet to provide, the myth remains a myth. I'm done.And I have stated basic science supports it, which you agreed with. Powder being abraded increases the surface area and thus will effect the burn rate.
