Quick Answer
Reloaded 7mm SAUM ammunition generally retains its performance and accuracy for 10 to 20 years when stored properly in a cool, dry place. After this period, the cartridges may still be usable but with a potential decrease in velocity and accuracy. The shelf life can be extended by keeping the ammunition in its original packaging and storing it away from direct sunlight.
Storage and Handling
When it comes to storing reloaded ammunition, proper handling and storage are crucial to maintaining its shelf life. Keep the cartridges in their original packaging, such as plastic or cardboard boxes, and store them in a cool, dry place away from direct sunlight. This can be a basement, garage, or storage room with a consistent temperature between 50°F and 70°F (10°C and 21°C) and humidity levels between 40% and 60%.
Factors Affecting Shelf Life
Several factors can affect the shelf life of reloaded 7mm SAUM ammunition, including storage conditions, handling, and the quality of the components used in the reload process. For example, exposure to heat, moisture, and vibrations can cause the primers to degrade, while direct sunlight can cause the propellant to break down. Using high-quality components and following proper reloading techniques can help minimize the risk of degradation.
Testing and Verification
To ensure the continued accuracy and performance of reloaded 7mm SAUM ammunition, it’s essential to test and verify its performance before using it for hunting. This can involve firing a few rounds at a target to check its accuracy and velocity, and also inspecting the cartridges for signs of degradation, such as excessive wear on the cases or primers. If the ammunition passes these tests, it can be safely used for hunting, but if it fails, it’s best to discard it and reload new cartridges.
