Quick Answer
Yes, the age of your ammunition can affect ballistic app readings, as older ammunition may experience velocity loss and pressure drops, which can impact its trajectory and accuracy.
Ammunition Shelf Life and Ballistic Performance
Ammunition shelf life is a critical factor to consider when calculating ballistic trajectories. Most manufacturers guarantee their ammunition for 10 to 15 years from the date of manufacture, but in reality, the shelf life can be shorter. The longer the ammunition sits on a shelf, the more prone it is to degradation, which can affect its velocity and pressure.
Factors Affecting Ammunition Shelf Life
Several factors can impact the shelf life of ammunition, including storage conditions, temperature, and handling. Ammunition stored in extreme temperatures, direct sunlight, or high humidity is more likely to degrade faster. Additionally, improper handling, such as excessive handling or exposure to moisture, can also reduce the shelf life. Generally, it’s recommended to store ammunition in a cool, dry place with minimal exposure to light.
Measuring Ammunition Performance
To ensure accurate ballistic readings, it’s essential to measure the performance of your ammunition. One way to do this is by conducting a chronograph test, which measures the velocity of the projectile. This can be done using a portable chronograph or a rifle-mounted chronograph. By measuring the velocity of multiple rounds, you can determine the average velocity and calculate the drop and wind deflection more accurately. This information can then be used to fine-tune your ballistic calculations and ensure a more accurate shot.
