Quick Answer
Environmental factors such as temperature, humidity, and wind resistance can significantly impact the accuracy of a 28 Nosler rifle, particularly in long-range shooting situations.
Temperature and Ballistic Coefficient
Temperature affects the ballistic coefficient (BC) of the 28 Nosler cartridge, leading to variations in accuracy at long ranges. A 10-degree Fahrenheit change in temperature can result in a 1-2 MOA shift in point of impact. To compensate, hunters should use a ballistic calculator or consult a BC chart to determine the optimal temperature for their specific load.
Humidity and Air Density
Humidity also impacts air density, which in turn affects the trajectory of the 28 Nosler bullet. At higher humidity levels (above 60%), the air density increases, resulting in a flatter trajectory and less wind deflection. However, at lower humidity levels (below 40%), the air density decreases, leading to a more pronounced wind deflection.
Wind Resistance and Angle
Wind resistance and angle also play a crucial role in long-range accuracy with the 28 Nosler. A 10 mph wind at a 90-degree angle can result in a 2-3 MOA shift in point of impact. Hunters should use a wind deflection chart or ballistic calculator to determine the optimal wind deflection compensation for their specific load and shooting conditions.
