[QUOTE="Jlusk, post: 1940821, member: 92365"] All powder degrades when heated. We have time/heat limits for ammunition in the military. The heat cycles start at 100 degrees ambient temp and go to 140 degrees plus ambient temp. Time factors can be days at 100 degrees, to only an hour or two at 140. If you have ever seen videos for military personnel burning or blowing up large amounts of small arms ammo it’s because the ammo is no longer safe to use or store. The military tries its best to keep ammo out of direct sunlight and stored in shaded or double walled storage containers, and those containers get daily temperature reading. When you go to the range or transport ammo, just be aware that an increase in the ammunition’s temperature above 100 degrees will start degrading the powder, the potential for over pressure when fired is one of the side effects of degraded powder. Chilling the ammo will not reverse the effects of powder that has been subjected to temps above 100 degrees. The chemical bounds are already broken and chilling will not cause them to rejoin.
