I use a turret press, so every case, new or used, gets resized since not resizing would disrupt my rhythm.
FWIW & YMMV - On the rare occasions I've deprimed cases with live primers, I've soaked them in a water based washing solution and deprimed them wet using a universal depriming die in a single stage press. (Damp rather than dripping wet and without a sizing mechanism in the die, there is some blow-by space.)
Long story short: Back in my early bottomfeeder days I "inherited" a bucket of primed .45acp cases and loaded a few.
They must have not been stored properly since I got 3 FTF out of the first 7 and I recovered the powder and bullets from the rest of the 50 I had loaded.
Not wanting to take the risk of depriming live primers and not knowing a good way to dispose of them safely, the cases lurked in my reloading stuff until I watched a documentary on the manufacture of rimfire cartridges. They load the primer material wet and then let it dry thoroughly before adding powder and bullet.
Using reverse engineering logic, I soaked a few primed cases in water with some dishwashing detergent added to reduce the surface tension of the water so if it would soak into the primer material better. I let them soak overnight and very carefully and slowly deprimed them.
Nothing went bang, so I eventually deprimed the rest of them that way.
Whether the primer material being wet or being very slow and gentle kept them from going off, I'm not sure.
But I am pretty sure that getting the primers wet doesn't make the dangerous process any more dangerous.
Keep safe, whatever you do,
John
