Does rifle/pistol brass deteriorate significantly over time?
Was reading the interesting thread earlier on tin/lead, and a quote there caught my eye:
"I have some boolits stored around here that are over 5 years old and I have yet to load them. They do not deteriorate with age although the same cannot be said of the brass. Some of the tumble cleaned stuff needs a polishing prior to reloading only for the tarnishing received over time even if kept in airtight plastic containers."
I guess I didn't realize that brass deteriorates over time, other than with "work hardening." Is that the case? Does it? I have a fair amount of 30 y/o brass that I am counting on using at some point.
Thanks,
