Quick Answer
Temperature Affects Reloading Powders, requiring careful consideration of storage and use conditions to ensure accuracy and safety.
Understanding Temperature Effects
Temperature significantly impacts the performance of reloading powders. As temperature increases, the burn rate of powders accelerates, potentially leading to over-pressure and reduced accuracy. Conversely, decreased temperatures can result in slower burn rates, reducing power and potentially causing incomplete ignition. For example, a temperature increase of 20°F (11°C) can result in a 10-15% increase in burn rate for many common powders.
Temperature Considerations for Storage and Use
Proper storage of reloading powders involves maintaining a consistent temperature between 60°F (15.5°C) and 70°F (21.1°C), with relative humidity below 60%. Ideal storage locations include climate-controlled rooms or cabinets with a consistent temperature. When loading ammunition, ensure the temperature in the loading area is within the recommended range for the specific powder being used, usually between 60°F (15.5°C) and 75°F (23.9°C). This helps prevent variations in burn rates and ensures consistent performance.
Practical Techniques for Managing Temperature Effects
To mitigate temperature-related issues, hunters can employ various techniques. For instance, when loading ammunition in hot or cold conditions, consider using powders with a wider operating temperature range. Additionally, load ammunition in batches using powders with consistent burn rates, even if it requires storing multiple powders at separate temperatures. This approach helps maintain consistency and ensures the performance of ammunition remains reliable across varying temperature conditions.
