Hi, so I'm aware that our powders should not be stored in a high heat environment as it can cause more rapid degradation , but what about afterburner are reloaded ? Is there a "shelf" life of loaded or factory ammo ? I read once no more than 10 years , no more than 30 years , avoid temperature fluctuations , the primers usually deteriorate first , etc... Anybody actually know for sure ? I have a friend who coats his primers with nail polish after reloading , swears that will prevent them from going bad in long term storage ? Thanks .
