Is it the heat or the percussion that sets them off? In the drier they would be bouncing around in a metal container.
Centerfire ammo needs a strong precise hit to the primer to set it off, I think that's statistically unlikely for a loose object like a screw or a zipper to set that off.
Rimfire ammo has the primer inside the rim of the base. I suppose it could be possible for a heavy tumble against a sharp metal ridge in the drum being enough to discharge the round.
Thanks, as you can tell Im not super well informed about firearms in general
