Brass tumbled, now what ???

A newbie question ... just got me a new tumbler and did my first tumbling run using corn media mixed with polish. Brass came out clean and polished after a couple of hours. They've all been de-primed and re-sized and all clear of any media. Do I still need to do any other cleaning after tumbling?
Thank you in advance for your support and understanding.

FEENIX, I tumble my brass before depriming. That way the primer pocket gets cleaned out. Never had a problem doing it that way with rifle or pistol brass in over 40yrs. loading [;)]
B17, I've never cleaned the primer pocket in any pistol brass, just tumble, decap, reload. Rifle brass same thing, except match [;)]
Just my humble opinion.[:)]
i do it to every shell
every time i decap
Thanks again.

Depending on your needs and goals you may want to turn the necks (inside, outside or both) if this is a rifle cartridge.
If all else is in irder, you appear to be ready to re-prime and charge your brass.
Just curious, did you re-size the brass BEFORE tumbling? That's the impression I get from the way your post is written. NOT a good idea!
The primer pocket have been thoroughly cleaned out before I invested on a tumbler and have done dummy run to make sure primer seats OK. I double checked my reloading manuals and don't seem to find any reference (or at least something that stands out) about cleaning it again after tumbling that's why I am soliciting your expert opinion.
Thanks again.

If you have the primer pockets cleaned before tumbling, the only thing I do before reloading is to make sure there is no media stuck in the primer hole.
With pistol brass and carbide dies no, just load and shoot. Lubed rifle brass needs the lube cleaned off before loading.

DCS I am puzzled by your answer.[?] How does the primer pocket get clean if the brass is tumbled before the primer is removed? Could you mean the Flash Hole?
PS. I tumble before all else. Easier to get the cases clean and keeps all the range crud out of the dies. Also sizing lube will shorten the media life. I also clean the primer pockets in a seperate operation as the posters above do.
My bad, they are once fired .300WM off my rifle, de-primed, primer pocket cleaned, re-sized, and trimmed/de-burred.

They are all Federal brass. I ran a batch of 50 ... only had to clean off media on 9 of them.
Thanks again.

The big question here is did you de-prime first or did you tumble first? The point of that question is the primer pocket or flash hole can fill with media and you may have a hangfire or no fire.
If you tumble afterward take a spare depriming stem (with pin) and run it through each of the flashholes in the cases. I've seen daylight in a plugged flash hole once, having done this once or twice, and noticed the hole wasn't round. I punched the pin in and sure enough I had some media stuck in the flash hole. It's okay to deprime then tumble just run the pin in after tumbling. It's quick enough. You can grab up ten cases at a time and punch a pin in just as fast. You can go through 100 in less than two minutes.
The reason I now tumble then deprime is it gives you a cleaner look at the case. For cleaning pockets I have a RCBS pocket primer brush. It goes fast but your hands get cramped a bit doing more than 100 or so. RCBS also makes an electric one on the Trim Mate.
