One guy took some ammo and tumbled it for different amounts of time. The longer tumbled ammo did show some of the powder breaking down.
Not knowing one guy's reputation, I'll go with the ammo and powder manufacturers.

Every manufacturer of ammo and tumblers cautions against it.
The experiments conducted in the referances is compelling I've still not seen a powder company say it was not dangerous.
Listen in this liability lawyer target rich environment you can't get anybody to put thier name or any test like this on paper.
Actually I wonder about smokeless powder breaking down vastly changing its burn rate.
I know this is true in regards to black powder, 4 F being much faster than 1F.
But with that said do we know beyond a doubt that Unique in a finer state would be similar to bullseye?
I think there is much more to burn rates in regards to smokeless powder than how fine it is.
So far, I've posted the facts as I know them. A careful read of my post will reveal the reps I spoke with (via email) advised against it, but not because of the possibility of affecting burn rate. One stated a hobbyist would probably never tumble to the degree they do.EDDIENFL.....read the post you referenced carefully. None say its ok and the references so far caution against it. I have, so far, tried to post what are facts, very vague at best.
Do YOU have anything in writing? I dont and never claimed to......yet.

JCWIT......did you read my previous post? I will post all the data when available. No sooner.
Her in NM we are blessed with some very sophisticated Labs, due to the proximity of Los Alamos, etc., and one of the great things about what I do is having gotten the opportunity to befriend some really smart people.
One of those friends is an engineer at the biggest one and has agreed to look into this matter for me. As a friend. WHEN, AND IF, we can actually get some hard evidence, I will gladly post it.
In the meantime, I will still CAUTION against it.
It seems that not any of the links I posted were met with anyone saying its OK. I am trying to post facts not hearsay. The only link that seemed to have merit was the one from the University.
I also suspect the Low Frequency of shipping or transport is nothing compared to the HIGH frequency of a tumbler.
I have found that some of the factories do tumble their loaded ammo(described on the websites) for a couple of minutes at most. The tumblers that they use(that I could find, look like armor!
I know tumbling ammo has been done, as I have done it, as earlier stated.
I suspect that under certain circumstances, with certain cartridges and powder, It is a factor.
I have seen the effects of High frequency on steel, aluminum, Titanium etc.
food for thought.....
