What role does wind play in shooting .308 at elk?

Understanding Wind Drift

Wind drift is a critical factor to consider when shooting at long distances, as it can significantly affect bullet trajectory. For a .308 Winchester, wind drift can be estimated at approximately 10-14 inches per minute of wind per 100 yards. For example, if the wind is blowing at 1 mph, a .308 bullet will drift about 12 inches at 200 yards and 24 inches at 400 yards. This means that for a 400-yard shot, a 1-mph wind will require a 12-inch correction.

Estimating Wind Speed and Direction

Accurate wind calls and range estimation are essential to make an effective shot. To estimate wind speed, look for signs such as tree sway, grass movement, or dust devils. You can also use a wind meter or anemometer to get an accurate reading. When estimating wind direction, look for signs such as leaf movement or smoke blowing in a certain direction. Keep in mind that wind direction can change quickly, so it’s essential to stay alert and re-estimate wind conditions regularly.

Compensating for Wind Drift

To compensate for wind drift, you’ll need to adjust your aim accordingly. The adjustment will depend on the wind speed, direction, and distance to the target. A general rule of thumb is to hold 1-2 inches high for every 10 mph of wind speed. For example, if the wind is blowing at 20 mph, you’ll need to hold 2-4 inches high. It’s essential to remember that this is a general rule and may vary depending on the specific rifle and ammunition being used. Always practice and develop your skills to accurately compensate for wind drift.
