Quick Answer
Weather conditions can significantly impact the accuracy of a .35 Whelen rifle during hunts, primarily due to wind, temperature, and humidity affecting bullet trajectory and expansion. However, proper gun handling, ballistics knowledge, and ammunition selection can mitigate these effects. Experienced hunters can still achieve accurate shots in various weather conditions.
Weather Conditions and Ballistics
The .35 Whelen rifle is a powerful cartridge designed for large game like elk. Its trajectory is relatively flat, but weather conditions can still affect its accuracy. Wind, in particular, is a significant factor. A 10 mph crosswind can deflect a .35 Whelen bullet by up to 10 inches at 200 yards, and by up to 20 inches at 300 yards. This requires hunters to compensate with wind calls or adjust their aiming point.
Temperature and Barometric Pressure
Temperature and barometric pressure also impact the .35 Whelen’s accuracy. A 20°F temperature change can affect the bullet’s trajectory by up to 1.5 inches at 200 yards. Hunters should be aware of these changes and adjust their aiming point accordingly. Additionally, barometric pressure can affect the expansion of the bullet upon impact, making it essential to choose the right ammunition for the conditions.
Ammunition Selection and Handling
To mitigate the effects of weather conditions, hunters can choose the right ammunition for the job. For example, a lighter bullet with a higher ballistic coefficient will be less affected by wind and temperature changes. Proper gun handling is also crucial, as a well-maintained rifle will perform consistently regardless of the weather. Hunters should ensure their rifle is sighted in, clean, and properly maintained before each hunt.
