Lubed Cast Bullet Shelf-Life

[tomcat13]

I was just given about 200 Cast Bullets that have already been Sized & Lubed (200g @ .401 for .40/10mm). Not sure exactly When these were Lubed, or with what & need to know IF anyone has experienced Bullet Lube deteriorating after sitting for 5-10(or more) yrs & becoming Ineffective @ preventing Bore Leading. Thanks in advance for any/all responses.

Forever if you don't overheat them or freeze them.

As above heat is your enemy when storing lubed bullets, if they havelube and they are consistent shoot them up i say

Some of the old bullet lubes that used bees wax and parafin wax together would dry a little and small bits will flake off, Not to worry, They are still good as long as most of the lube is still there.
