How to read wind conditions while shooting with 6x47 Lapua?

Identifying Wind Patterns

When shooting in the field, it’s essential to identify wind patterns. Start by observing the wind direction, which can be determined by blowing leaves, smoke, or dust. In areas with no visible indicators, you can use the sun as a reference. The wind tends to blow from high pressure to low pressure, and in most cases, this is from the northwest in the northern hemisphere.

The next step is to estimate the wind speed, which can be done by observing how much the leaves or grass are swaying. A gentle breeze is around 5-7 mph, while a stronger wind is around 10-15 mph. It’s also crucial to note the wind gusts, which can be much stronger than the average wind speed. In most cases, the wind gusts can be around 20-30% stronger than the average wind speed.

Applying Wind Adjustments to the 6x47 Lapua

To apply wind adjustments to your 6x47 Lapua, you need to understand the ballistics of the cartridge. The 6x47 Lapua has a relatively low wind drift due to its long barrel and heavy bullet. However, it still has a wind drift of around 4-5 inches per 10 mph of wind at 100 yards. To compensate for this, you need to adjust your aim slightly upwind. A general rule of thumb is to adjust one click per 5 mph of wind, taking into account the wind direction and gusts.

Using Wind-Reading Techniques

There are several wind-reading techniques you can use to improve your accuracy, including the “flag method” and the “target method.” The flag method involves observing the movement of a flag or a stick in the wind, while the target method involves observing the movement of a target or a landmark in the wind. Both methods can give you a more accurate reading of the wind direction and speed, allowing you to make precise adjustments to your aim.
