What is one key factor affecting the shelf life of ammunition?

The shelf life of ammunition is significantly influenced by storage conditions. Proper storage conditions, including temperature, humidity, and exposure to corrosive environments, play a crucial role in maintaining the integrity and functionality of ammunition over time. When ammunition is stored in environments that are too hot, too humid, or exposed to moisture, it can lead to degradation of gunpowder, corrosion of casings, and overall deterioration, reducing the effectiveness and safety of the ammunition. Proper storage involves keeping ammunition in a cool, dry place, ideally in a climate-controlled environment, to ensure longevity and reliability when needed.

While factors such as the color of the packaging, the brand of ammunition, and the type of container can have some impact on the overall presentation and convenience, they do not fundamentally determine the shelf life of the ammunition in the same way that environmental conditions do.
