Tumbling after priming

Why would you tumble primed but not loaded brass?

But to answer your Q- you could get a piece of media wedged in the flash hole and not know it. If it would cause a Kaboom, poor accuracy, or nothing at all is speculation.

ETA: If you mean "tumble loaded rounds", then there is no problem there. Factory ammo mfgrs do it, as do some hand loaders
 
Ditto to what roccobro said. When the primer is already seated you may not be able to see what else might be stuck in there and that's assuming you even remember to eye each one.
 
Yeah, that's the reason I asked. I just wanted to get them shiny. No big deal. I know that manufacturers tumble loaded rounds, but I just don't feel comfortable doing that. I'll just leave them dull.
 
Isn't tumbling loaded rounds supposed to break up some types of powder, which can spike burn rates and pressure curves to dangerous levels?
 
No.

A piece of media in a flash hole stands no (zero, nada) chance of causing a "kaboom" etc. Tumbling loaded rounds a reasonable length of time will not degrade the powder and cause kabooms.

I assume you are talking primed unloaded cases, so the powder thing is a non issue anyway.

I don't myself. I tumble before sizing. Then I load it. Then it is still clean enough for me.

But no, it won't hurt anything.

This has been discussed over and over and the answer is NO!

Walkalong's post is correct.
 
06-01-08 I did a little experiment to try to answer the question,,--"does a chunk of media in the flash hole cause problems?" See the thread here;

Now, TonyA doesn't mention what brass he's tumbling after being primed. These in my test were .223.

And,,,,---- nothing was solved, no conclusion was reached. I just avoid tumbling after re-sizing, unless I tumble the completed round.
 
Yes, these are .223 Lake City brass (or 5.56 is you prefer).

Thanks guys. I think I've solved my dilemma. I'm send all of my brass out to be processed from now on.

Why! Load them, then tumble them. Next time tumble them before priming. Very simple.
