Quick Answer
Your rifle shoots high at long distances due to the drop of the bullet in relation to the trajectory, often caused by the rifle's sight settings, environmental conditions, or the shooter's technique.
Sight Settings and Adjustments
When shooting at long distances, your rifle may shoot high due to improper sight settings. Typically, a 100-yard zero is set for the rifle’s sights. However, for longer distances, this zero may be off by as much as 2-4 inches per 100 yards. To adjust for this, you can use a trajectory chart or consult with a ballistics expert to determine the correct sight setting for your specific rifle and ammunition. In general, for every 100 yards beyond the initial zero, you can add 2-4 MOA (minutes of angle) to the elevation setting.
Environmental Conditions and Ballistic Factors
Additionally, environmental conditions such as wind, temperature, and humidity can significantly impact the trajectory of your bullet. Wind deflection, in particular, can cause your rifle to shoot high or low, depending on the direction and speed of the wind. Temperature and humidity can also affect the expansion and contraction of the bullet, which can impact its trajectory. When shooting at long distances, it’s essential to consider these environmental factors and adjust your shot accordingly.
Shooter Technique and Grip Position
Finally, the shooter’s technique and grip position can also contribute to the rifle shooting high at long distances. A loose or improper grip can cause the rifle to rise or dip during the shot, resulting in a high or low impact point. To correct this, ensure a firm, consistent grip on the rifle, with your dominant hand positioned on the pistol grip and your support hand on the fore-end. This will provide a stable platform for the rifle and help you maintain a consistent aiming point.
