How can temperature affect 7mm SAUM ballistics during a hunt?

Temperature’s Effect on Velocity

When hunting in cold temperatures, the 7mm SAUM’s velocity will be lower due to the decreased air density. A 20°F decrease in temperature can reduce the velocity of a 7mm SAUM by approximately 30-40 fps. This means a 150-grain bullet might lose 50-60 fps of velocity, reducing its effective range. Conversely, hot temperatures can increase the velocity, but also increase the bullet’s aerodynamic drag, further affecting its trajectory.

Understanding Temperature-Related Ballistic Changes

As temperature changes, so does the bullet’s aerodynamic characteristics. In cold temperatures, the bullet’s air resistance decreases, allowing it to travel farther and maintain its trajectory better. Conversely, hot temperatures increase air resistance, causing the bullet to drop faster and travel shorter distances. Understanding these changes is crucial when adjusting your shooting techniques and choosing the right ammunition for hunting in varying temperature conditions.

Hunting in Extreme Temperatures

When hunting in extremely cold temperatures (below 20°F), use a heavier bullet (150-160 grains) to maintain enough kinetic energy for effective range and penetration. Conversely, in very hot temperatures (above 90°F), use a lighter bullet (120-140 grains) to mitigate the effects of increased aerodynamic drag. This allows hunters to adapt their load to the environment and ensure accurate, effective shots in various temperature conditions.
