I find I neglect them so too many turn into a pile pf cleaning procrastination.
My reason for many is I teach youth firearms safety so I have one in every action and they are cheap to shoot...
However I've noticed I only grab my cz 452 now; even when I need a skunk gun in the truck for family farm visits. I could sell all of them except the 452 and my 39a...
and better keep the 77/22,
and I better keep the rem 121...
and I better....
(sense a pattern here...)
