Quick Answer
Yes, you should adjust your scope based on ballistic app readings to ensure accurate shots at varying distances, considering different ballistic coefficients and environmental factors.
Understanding Ballistic Apps
Ballistic apps can predict bullet trajectory with remarkable accuracy. When sighting in your rifle, use the app to determine the optimal scope setting based on your specific ammunition, rifle, and environmental conditions. Most apps will ask for data such as muzzle velocity, bullet weight, and the rifle’s ballistic coefficient. For example, if your app recommends a 20-inch adjustment at 100 yards to compensate for a 50-grain bullet’s wind drift, make that adjustment in your scope.
Adjusting for Environmental Conditions
Different environmental conditions can significantly affect bullet trajectory. Temperature, humidity, and air density can all impact the flight of your bullet. Ballistic apps account for these factors when calculating trajectory. For instance, a 50-grain bullet may require an additional 3.5-inch adjustment at 200 yards if the temperature drops by 20 degrees Fahrenheit. Make sure to enter this data into your app to ensure accurate calculations.
Scope Adjustment Techniques
To make adjustments in your scope, use a 1/4 MOA click value as a standard. This means turning the adjustment dial 1/4 of a minute of angle (MOA) per click. For example, if your app recommends a 10-MOA adjustment at 100 yards, turn the dial 25 times to make that adjustment (10 MOA / 0.4 MOA per click). Always make small adjustments and re-zero your scope after each change to ensure you’re on target.
