Load a revolver and an auto and leave them in a sock drawer for 30 years with no maintenance. I would guess (just a guess) that the most revolvers would make it through a box of ammo with less trouble than most auto.
I've handled some of those sock drawer revolvers whose internals had all but locked up from accumulated crud to the point where it was near impossible to pull the trigger double action. Some of them had sat in the drawer for a lot less than 30 years.
