De-prime or not?

Can the experts please chime in whether or not it makes any difference on accuracy, functionality, etc depriming the case prior to wet tumbling. I know that depriming allows the primer pocket to be cleaned and it does look a lot “prettier “, but does it make any difference?
Thanks in advance for your feedback.

I don't think it makes any difference, but I deprime.  Primarily to keep all the contaminants out of the waste water.  Downside is I am going on my 2nd FAT 50 ammo can of spent primers.

Deprime, otherwise you're gonna trap water in the primer pocket that may or may not dry before you try to reload.

I’ve found it makes little difference in Pistol. In rifle, the cases dry faster so they are usually deprimed first.

I don't deprime prior wet tumbling. I don't want to add another step to reloading. After I sift the pins out, I dry the brass in a dryer. I used to just lay the cleaned brass out on a fender cover over the weekend.  I've never had any problems with trapped water or misfires.

I always deprime my casings prior to stainless steel media tumbling. It cleans the primer pockets beautifully and allows me to inspect the flash hole prior to re-priming the case.

No de-priming for pistol for me.  I clean brass in Ultrasonic cleaner and then dry it in NESCO Dehydrator (as Ashley suggested in different post).  Resulting brass is squeaky clean.  I don't see any effect on accuracy, and it is rather "work flow" issue than anything else.  So I'm with Kurt The Evil on this topic.

No de-priming for me. Just a step that isn't needed. I drop them in the ultrasonic for about an hour then I let them tumble/dry in the media for a couple of hours. The brass comes out bright, dry and slick. By slick I mean the little bit of wax in the media lets them squirt right thru the press. De-priming also the number one cause to get media stuck in brass and press. Brand new un-primed brass just gets a squirt of "one shot"

No de-priming? Nothing like spreading lapping compound on your nice reloading machine base.
Here's the base of an old Star machine I bought cheap and am going to weld up and re-machine.

It sure seems intuitive to decap before cleaning the brass.  How else could you get trapped residue from the primer pocket?  May not effect accuracy but the pocket must remain "dirty"; not a good practice.

I found that my Dillon SD stays clean a lot longer if I decap  first with a universal deprime die
and the primer feeder works better!
