The ideal maximum storage temperature for ammunition is regarded as under 80°F (27°C). Storing ammunition at this temperature helps ensure its longevity and reliability. Extreme temperatures, particularly heat, can negatively affect the components of ammunition, such as the propellant and primer, potentially leading to misfires or other malfunctions.

Propellant can degrade over time when stored in high temperatures, which may alter its burning rate and performance. Additionally, temperature fluctuations can lead to moisture retention within the ammunition packaging, which might cause corrosion or other forms of degradation.

While temperatures lower than 80°F are generally acceptable for ammunition storage, maintaining a cool environment helps protect the integrity of the ammunition, ensuring that it performs as expected when needed. This is vital for safety and operational effectiveness, especially for individuals who rely on ammunition for self-defense or recreational shooting.
