Per the title; How long can ammo with soft polymer tips or inserts last before the polymer becomes hard and the bullets don't expand as they should?
To take all other variables from the equation lets say it's stored at 65-85 degrees F (75 degrees F average) in sealed ammo cans with plenty of dessicant (zero percent humidity).
ETA #1: This is important to me because I'm buying for long-term storage.
ETA #2: To clarify, this is ammo that uses polymer tips/inserts to prevent clogging of the hollow point and/or (supposedly) aid in bullet flight accuracy. During hydraulic shock the rubber deforms, more-or-less, as if it wasn't there. However, as the tip/insert hardens, it seems logical to me that it would hinder expansion.
ETA #3: My definitinon of "long-term" is 20 years with no noticible change in the polymer.
