I also tumble before sizing/decap.
Clean brass is easier on the sizing die.
If the brass is clean after firing I skip the tumbling.

I tumble primed to get the ick off before sizing.
I don't like running dirty cases through the dies. One grit and you've messed up a die so it scratches ALL your brass.
If the primer pockets are cruddy, I'll size and decap and then tumble again, that cleans them up a little but not spit-shined.
But normally, it's just tumble, size, prime and load. If you have a media separator and keep your media unclogged, you should almost never break a pin.

Guys, I wipe my brass down with a soft cloth before resizing. This cleans the brass and helps to find any small crack or flaw. The I resize, deprime, and tumble. How is a soft brass case gonna imbed a grain of sand into a hard steel die? I have dies that are over 50yo and they're still working fine. Can someone cite me an actual case of dies being damaged? I'm not talking about some clutz that would pick up a piece of brass off of the ground and cram it it a die.

I have done it both ways,primers in/out.

I have bought 2 types of the de-priming dies and they work well,even when brass is tumbled with the primers in.

Yes,i have broken several of the pins but it was due to those pesky double holed cases.

If the brass is not really cruddy i just wipe and reload.

yeah I have broken the pins because of those doube hole cases. Think there are called beran or boxer primers. hard to tell whether some fired cases handed to me is double holed with the primers still in. any way you can tell whether a case is doubleholed with the primer still in?

Berdan = two holes. Pretty much considered un-reloadable. Mostly found in foreign milsup ammo
Boxer = 1 hole. standard for domestic ammo and brass. reloadable.
no way of knowing from outward appearance whether it's Berden or Boxer. The head stamp can be a clue.

What Still says: Berdans are one-time only, but if you got desperate, you could make a bushed drill sleeve and poke them for Boxer. Been thinking about trying that for fun.
As for your scratching question, Still, I have cootied a die. I got a hunk of grit somewhere, it bedded itself in the brass and put a ding in the die. Soft metal with a large bearing surface can hold a hard thing to wreck the harder metal...sho nuff.
Thank God for die grinders. Took some nit-picking work but I got rid of the cootie and the die works fine.

I don't care if the case is shiny or not. I don't want the grit in my dies. A good inspection of the cases will prevent any problems with media stuck in the primer pocket.
