I did search on Boolits and this forum but couldn't find info.  I'm probably using the wrong words.

Once molded, do lead bullets have a "storage life?"  That is, should I only mold what I can use in a certain amount of time.   Once lubed, how long before I should shoot them?  I know the lead can look funky after awhile and lube can dry out.  Are there some guidelines posted, storage methods?  Thanks.

Alloys containing Antimony will age harden over the course of a few weeks.
All cast that is stored dry will last forever litteraly.
If vaccuum sealed i think greased bullets will last just as long. Unless the grease contains corossive ingredients, salt comes to mind, and nonrefined oils can have assidic residue (coldpressed oliveoil).

The lead will last forever, but the lube?  Well that depends on the lube.  I have found that some lubes tend to dry out over a year or so; some don't.  If you can seal lubricated bullets from the atmosphere they will probably last a long time.  The trick is sealing them.  When I first started shooting, my rifle was an Argentine Remington in 43 Spanish ($14.95).  I was shooting original ammunition ($5.00/100 at Ye Ole Hunter) and the lube worked fine.  That ammunition had to be about 65 to 75 years old at the time (1960-62).

As I recall, and it may be from Dell's book, our lead tin alloy cast bullets can change BHN as they age---getting softer over time as I recall. I seem to remember seeing an age/hardness chart somewhere.
When I was shooting my 45-70 I would cast my bullets during the winter, dropping them from the mold into a bucket of cold water (with a  towel in the bottom to reduce battering)  I would then let them air dry and seal them in ziploc vacuum bags in batches of 100 and store them in a freezer. (being single, bags of bullets in the freezer with the venison wasn't an issue) 
Prior to a match I'd take an adequate supply out, put them in a pie pan and warm them to about 200 degrees for an hour, air cool, and then pan lube.
 My idea was that specific batch would be of a reasonably uniform hardness.   
Who knows it might have actually helped my scores, if the moon was right and I was holding my tongue in just the right part of my cheek.
Now that I'm working my way back into center fire shooting I may resume that practice.

I wonder how long the commercial cast bullet mfgs hold their cast and lubed packaged bullets in inventory.  Inventory economics must have a lot to do with it.

Thanks for the info guys.  My first and last episode for molding .32-40 (Hoch 210gr non-tapered) was a dismal failure with 50% thrown back in.  This winter I plan of making a large batch and beating up anyone who disturbs my concentration.

Fitz nailed it, once you start don't stop and go as quickly as possible. His advice on casting several years back is what got me started on the right path to match quality bullets while using a ladle.
