What interesting replies. The answer seems to be, no and yes, depending on things like how often do we shoot and whether we are shooting the rarer calibre's.
I think for me, especially nowdays it's not worth the effort. Gone are the days when I would reload a couple of hundred .357s and 9mm's the day before a range visit. I have the same press I had forty years ago, and various dies, but ammo is not expensive, everything I use can be mil spec ball. Except for my 1894c, but I try not to put silly amounts through, for fear of waring it out. Its a 1990s JM and I like it a lot.
So no, maybe not worth it, for me anyway.
