Some guns and some cartridges are worse than others in this rechambering scenario.
At my department I have a box left out of duty handgun ammo and rifle ammo, rifles do it too, sometimes even worse.
Officers are instructed to check for setback and bullet deformation and to use a new round when appropriate.
Myself I generally rotate the mag stack. I'll flip out some rounds and use a new one for the chamber, put the old one bottom of the stack etc. Not as diligent as I used to be. Used to swap and rest mags every two weeks, used to do a lot of things I don't bother with now days.
First I've heard of the primer compound pulverizing, could happen, never seen it myself but again there's lots of things I ain't seen too.

Cue sound of Head slap.
