How to Dope a Scope – Full Overview, FAQs & More

People ask many questions about scopes and this question is one of them…

How to DOPE a scope?

Well, we are here to answer that!

Dope Out with Precision

Precision shooters use dope to improve accuracy. You need a chronograph (a stopwatch) in your hands and range time in your mind to be successful.

Hit the Target Around the Clock

Chronographs give us measurements of the average velocity of our bullets. Standard deviations tell us how consistent or inconsistent our bullets are. Knowing these numbers helps us understand our bullet performance and hit probabilities.

Only Time Can Tell

You should be aware of several factors that affect the accuracy of your projectile calculations. These include the type of ammunition, the caliber of ammunition, the distance between the target and the gun, and the angle of fire.

You might find an error or 2 as you track your scope. In some cases, there may be variations in the data and points of impact.

Getting Real with Your DOPEs

You can use an old-fashioned method to measure ammo. This is a simple process to follow. First, take out your gun and load up some rounds. Then, place them on a table or countertop. Next, take a ruler and measure the distance between each round. After doing this, you’ll be able to figure out how many shots you need to make your next shot count.

When shooting long range, you must use accurate data. You set your targets out at different distances, then measure the difference between them. This gives you enough information to calculate the mil or MOA.

After the first shot was fired, the bullet traveled about 1/3 of the distance before hitting the target.

Dial In Information

There is an easier way to get around obstacles. You can use elevation to avoid them. You must walk the impact point to reach your goal.

You’ve got to be careful when using your dope card. Don’t forget to check what you have recorded before pressing the button!

How to DOPE A Scope?

Congrats! You are finally learning how to use a rifle correctly by using scopes. Dope means to dope up or to make something better. In this case, you are making your rifle more accurate.

What is DOPE?

Data on previous engagements or DOPE is a collection of ballistic coefficient charts that contain all the information needed to understand elevation and wind. This is useful information to know about when shooting targets at a distance.

There are several different types of DOPE (Distant Object Penetrating Energy) weapons available. Some are designed to penetrate targets up to 100 meters away while others are more effective at shooting at targets within 10 meters. Most DOPE weapons are designed to fire bullets, but some are designed to fire energy beams instead.

DOPE Setup

Precision shooting requires a chronograph to measure the true velocity of the bullets. You should shoot directly over the chronograph to obtain the mean data and also standard deviations in the mean value. This way you’ll be prepared for any changes in velocity.

To get closer to the actual amount of time it takes for the bullet to leave the barrel, range time is very crucial to keep track of. Inconsistent errors will always be present due to human error and other minute variables affecting the actual data. But shooting two or three shots should provide you with close-to-accurate data. There are some apps available that help you counter these inconsistencies. You need to shoot a few distances, then calculate the percentage correction, then enter this new information into the app.

Real World DOPE

In any case, if you’re unable to find the manufacturer on the internet or you’re using a less popular ammo brand, you can still get the info using old-school manual measurements. You’ll need a few targets at different ranges; measure the distance from your gun to the point of impact; measure the time it takes to reach the point of impact; then use those numbers to calculate the mil or MOA.

This is a simple but effective method of measuring range. You should record the distance between the two points when the impact occurs. Then, you can measure the distance again later. When you do, you’ll see that the distance increases by the same amount.

You could also use a gear tie and wrap it around the barrel of your gun. Hold out the ends as if you were holding up a vertical hanging poster. Write down everything you’ll need to crosscheck on a piece of paper and clip it into place.

This helps you cut down on the time wasted in moving around and helps you keep your eyes on the target without having to recalibrate yourself. You don’t have to look up and down only to readjust your sights.

What is Scope Dope?

The Scope Dope kit includes a quick reference ballistic data disk designed to fit inside the flip-open rifle scope cap. The Scope Dope also includes a rectangular range card. Both items are made from heavy die-cut vinyl combined with ultra-durable UV-cured printing for a professional look.

A waterproof data disc is attached to the top of the scope cap. This allows you to record important information such as bullet type, caliber, weight, etc.

Scope dope is a great scope for all types of shooters. It works perfectly with any rifle scope model. It is made by a company that makes other great scopes.

How To Dope A Scope?

A scope is a device used to focus a weapon’s bullet onto a target. In this case, we’re talking about a rifle scope. When you dope a scope, you’re adjusting the settings on the scope to make sure your bullets are hitting the target. This means that if you dope a scope, the data collected by the scope won’t be useful for anything else.

That said, it’s still important to aim your gun correctly. You should know how to use your weapon properly before you start shooting.

In Lieu of Doping…

Ballistic data is easily accessible online. You don’t need to go through an involved process to get accurate information about your ammo.

A little research can be a great help when you’re doing your calculations.

Capturing Detail

Wind meters measure wind speed by measuring air pressure. You can use them to determine whether or not there is a breeze.

You should use a chronograph to measure the muzzle velocity of your rounds. It’s an expensive tool, but it’s necessary if you want to accurately calculate bullet drops.

A Dope-ist needs to know how fast the bullets fly, what the bullet drop is, what the wind is doing, humidity, atmospheric pressure, and more.

Tips For Doping A Scope

  • There are a few tricks to make the dope go a little faster and easier to use. First if you have flip up covers on your scope, put some basic dope sheets right there on the inside cover so you can easily see them without moving your head much (I’ve seen plenty of shooters using things like gear ties or bull dog clips to mount their cards on something too).
  • Gear ties are useful for keeping your rifle steady during long-range shooting. You should use them even if you aren’t worried about throwing things off. Your rifle shouldn’t be moved around too much or you may lose accuracy. Anchoring your rifle before firing helps prevent this.
  • Shooting ranges give people confidence by showing them what they can do. A person who shoots once or twice a year is likely to get better. New shooters need to practice often to become confident. Firing ammunition helps people improve their accuracy.


We hope that now you know how to DOPE your scope!
