How to Dope a Scope Correctly?

What Does Dope-Ing a Scope Means? 

DOPE stands for “Data on previous engagement.” Additionally, other than street slang, DOPE-ing a scope means to measure and collect ballistic data correctly while shooting at various intervals so that you may quickly adjust your windage and elevation dials such that your initial round lands precisely. 

In reality, when you DOPE a scope, the information you gather is about the ballistics of the shooting, and adjust your configuration for different distances and shooting situations. Any scope with identical click values will behave the same way. You’re not compiling any data on the scope itself.

1. Capturing Details Neatly

The outcome depends on the level of detail you’re recording. Grasp the bullet drops at different intervals by observing and measuring the impact point. It may need some walking, or you can have someone as a spotter. 

The tools required for capturing essential details are: 

  • A wind meter to know the wind speed to estimate a wind hold. 
  • A rangefinder is to measures the target distance from the shooting point. 
  • A Ballistic chronograph to measure the actual velocity of the fired ammo is one of the most significant pieces of information for computing information. 

2. The Basic Steps to Collect the Ballistic Data 

Again, it depends on what proportion of information you’re capturing. Here’s a breakdown of everything a true DOPE-ist should capture:

  • Muzzle velocity of the round 
  • Bullet drop at every distance
  • The elevation difference between you and your desired elevation
  • Wind speed and its impact on the bullet at various distances

Step 1. Capture the Muzzle Velocity 

  • Capture the muzzle velocity of the bullet using a Ballistic chronograph. A Ballistic chronograph saves you a lot of time putting the rest of the ballistic data in place. Use a calculator so that you gain specific ballistics by plugging in the essential information on your set-up.

Step 2. Set Up Your Instruments 

Once you’ve determined the muzzle velocity, you’ll need to set up your instruments and prepare your rifle. Use a gun stand to hold the rifle precisely. It improves the accuracy of your measurements.

Step 3. Set Up Your Target Distance 

Set up targets at the distances for which you’ll need exact figures. Furthermore, note that the distance of your target depends on your scope magnification. Calculate the exact distance between impact and the aim point with a rangefinder or with a spotting scope. 

Step 4. Shoot and Note the Ballistic Data 

  • Shoot enough shots at each range to be sure of the impact point. Take five-shot rounds at each range. You can take more rounds at the target if you want to gain confidence at a range.
  • At each location, note the wind speed, MOA, and bullet drop. The velocity will fluctuate each time you shoot; therefore, you wish to capture the average velocity.

3. Using the Data and Adjusting the Configuration 

The total goal of Doping is to be ready to reference a chart quickly that tells you the way to maneuver your aim point or scope network to create positive data that matches the purpose of impact. For example, most DOPE data cards include these values and look similar:

Range Drop + Time Velocity Wind M.O.A
50 YARDS -0.8 in 0.11s 2773 fps 0.3 0.4
100 YARDS -1.2 in 0.25s 2650 fps 0.6 0.7
200 YARDS -2.4 in 0.36s 2413 fps 0.9 1.5
300 YARDS -5.2 in 0.52s 2189 fps 1.2 3.5

After collecting the ballistic data accurately, follow the following steps:- 

  • First, Adjust your windage and elevation on what your scope uses and your preference. Second, Format it however you want; however, keep in mind the goal is to predict the impact point to hit a smaller target instead of hit low or high. Your Dope card ought to have the information you need.
  • Information you input to calculate the aiming variates just like the average velocity of the muzzle. Therefore, the actual velocity in several conditions and ranges doesn’t precisely match the data.

Tips for Doping a Scope 

There are a couple of tricks to creating the DOPE that go quicker and easier to use. 

  • First, if you have flip-up caps on your scope, place a basic tip sheet right inside of the cap; therefore, you’ll be able to see the datasheet while not moving your head much simply. A gear tie can work. However, it’s difficult to put it somewhere that you don’t have to worry about finding things from the paper.
  • Second, opt for the distances you shoot, supporting what quiet shooting you’re doing, whereas it’s lightweight outside. Also, have the rifle anchored once you fireplace. Therefore, you don’t throw things off. Moreover, Confidence depends plenty on the number of rounds fired.


In conclusion, long-range shooting has extreme importance. Thanks to Dope scopes. Perfectly doping a scope will make you hit the bull’s eye subsequently. Additionally, it’s indeed a necessary step in shooting precisely. You want you’re aiming to match and hit the target every time, no matter what scopes or tools you’re using.
