What were the weather conditions?
Remember, your kestrel automatically calculates AJ. This means winds from the left push down on an RH twist barrel, while winds from the right push up. Ensure your azimuth and wind directions are correct. Also, note berms/obstacles underneath your line of fire. Depending on wind direction, they can push your impact high. Finally, remember, Sun's up, Gun's up. When you have a lot of mirage, the target will appear higher.
