How does temperature affect turkey load performance?

Temperature Effects on Ballistics

When it comes to turkey hunting, temperature plays a significant role in the ballistic performance of your 12 gauge load. As temperature increases, the air density decreases, which can cause your shot to drop more and travel further than anticipated. This is why it’s essential to adjust your shot placement and lead accordingly.

For example, a 12 gauge 3-inch shell loaded with a 1 1/8 oz. lead projectile will drop 3.5 inches at 50 yards and 7.5 inches at 100 yards in temperatures above 80°F (27°C). In contrast, in temperatures below 40°F (4°C), the same shell will drop 2.5 inches at 50 yards and 5.5 inches at 100 yards. This means you need to adjust your aim point by 10-15 inches at 50 yards and 20-25 inches at 100 yards when shooting in cold temperatures.

Understanding Temperature Corrections

To accurately compensate for temperature-driven ballistic shifts, you need to understand the concept of temperature corrections. The most common method is to use a ballistic calculator or a table to determine the temperature correction for your specific load and distance. For a 12 gauge 3-inch shell loaded with a 1 1/8 oz. lead projectile, the temperature correction is as follows: -0.35 inches at 50 yards and -0.75 inches at 100 yards for every 10°F (5.6°C) increase in temperature above 70°F (21.1°C).

Practical Applications for Turkey Hunting

When turkey hunting, it’s essential to consider the temperature and adjust your shot placement accordingly. If you’re shooting in warm temperatures, you may need to aim higher to compensate for the increased drop. Conversely, in cold temperatures, you can aim lower to account for the reduced drop. By understanding the effects of temperature on your 12 gauge load, you can improve your accuracy and increase your chances of taking down that gobbler.
