This will sound crazy also but It doesn’t make sense to me to have safe space and reloading space taken up by a caliber that I hardly shoot anymore.
That doesn't sound crazy at all to me. I've mentioned several times here on THR that my wife and I are
both into guns, shooting and hunting, and because of that, we don't have room in our safes for any more guns, and we don't have room in this house for any more safes.
We're not going to buy a bigger house either - THAT would be crazy! We're in our '70s for crying out loud! And we, like you, don't shoot some of the guns we already have very often any more. Consequently, for a long time now, whenever my wife or I have a new/different gun in mind, we
usually (but not always) think about which gun we're willing to sell off, or trade in.
Crazy? Naw, not in my opinion.
BTW, at my wife's and my respective ages, we're also thinking about which guns to give to which kids, and which grandkids.
