Quick Answer
Cheap factory loads are generally safe for long-term storage, but their shelf life is shorter than more expensive options due to the use of lower-grade propellants and primers.
Factors Affecting Shelf Life
When choosing cheap factory loads for long-term storage, consider the propellant type and age. For example, the shelf life of a standard double-base propellant like IMR 4895 is 10 to 15 years, while that of a single-base propellant like IMR 3031 is 5 to 7 years. Always check the expiration date or manufacturing code on the packaging.
Storage and Handling
To maintain the shelf life of cheap factory loads, store them in a cool, dry place, away from direct sunlight and moisture. Aim for a temperature range of 50°F to 70°F (10°C to 21°C) and humidity levels below 60%. Keep the ammunition in its original packaging and avoid stacking or crushing the cases.
Reloading as an Alternative
If you’re concerned about the shelf life of cheap factory loads, consider reloading your own ammunition. This allows you to choose high-quality propellants and primers, which have longer shelf lives. For example, Reloder 15 has a shelf life of 20 to 25 years, while CCI 200 primers have a shelf life of 10 to 15 years. Reloading also gives you control over the loading process and allows you to optimize the ballistic performance of your cartridges.
