A riflescope doesn't have one setting that works perfectly for every distance.
As your target moves from closer to farther away, you may need to adjust your magnification, use your reticle, or account for changes in your bullet's trajectory. Understanding how these features work together can help you get a clearer sight picture and make more informed adjustments.
Whether you're using an LPVO for closer to mid-range shooting or a high-magnification precision riflescope for longer distances, the basic idea is the same: match your scope settings to the shooting situation.
Here's how to get started with your ARKEN riflescope.
1. Start With a Confirmed Zero
Before using your scope at different distances, start with a confirmed zero at a known distance.
Your zero is the distance at which your rifle and scope are set up so that your point of aim and point of impact match each other.
For example, if your rifle is zeroed at 100 yards, that 100-yard zero becomes your reference point when you move to other distances.
Your point of impact (POI) will not remain the same at every distance. Gravity affects the bullet's trajectory, and the amount of drop changes with distance, so you may need to account for that change.
That's why zeroing should always come first.
Tip: Always confirm your zero with your actual rifle, ammunition, and shooting setup rather than relying on a general rule.
2. Choose Riflescope Magnification Based on the Situation
One of the most noticeable adjustments you can make is magnification.
It's tempting to think that more magnification is always better, especially when shooting at longer distances. In practice, the most useful magnification depends on the target, distance, movement, and how much of the surrounding area you need to see.
Closer Distances: Keep a Wider Field of View
At shorter distances, lower magnification can make it easier to locate your target and maintain a wider field of view.
For example, an LPVO such as the ARKEN EP-8 1-8x28 FFP starts at 1x, giving you a low-magnification option when a wider field of view and quick target acquisition are priorities.
See the ARKEN EP-8 1-8x28 FFP at true 1x, with a wide field of view for close-range target acquisition.
Mid-Range Distances: Find the Balance
As the target gets farther away, increasing magnification can make it easier to see details and aim more precisely.
For mid-range shooting, a moderate magnification setting can provide enough detail without unnecessarily narrowing your field of view.

Longer Distances: Increase Magnification When It Helps
At longer distances, a higher magnification setting can make smaller targets easier to see and provide a more detailed sight picture.
The EP-8, for example, ranges from 1x to 8x, letting you increase magnification when you need more detail. Higher magnification can also help with precise shot placement at closer distances, depending on the target and shooting conditions.
For a higher-magnification setup, scopes such as the ARKEN EP-5 GENII 5-25×56 FFP provide a much wider magnification range for shooters working with smaller or more distant targets.
But remember: maximum magnification isn't automatically the best magnification.
The goal is to use enough magnification to see and aim at your target clearly while maintaining a useful sight picture.
3. Pay Attention to Your Field of View
Magnification and field of view are closely connected.
As magnification increases, the portion of the scene you can see through the scope generally becomes smaller. This can provide more target detail, but the narrower field of view can make target acquisition more difficult.
That's why a lower magnification setting can be useful when you need to find a target quickly, while higher magnification can be helpful when precise aiming and target detail become more important.
A simple way to think about it:
-
Lower magnification → wider field of view → easier target acquisition
-
Higher magnification → more target detail → narrower field of view
There isn't a single correct setting for every distance. The right choice depends on what you're trying to see and how you're shooting.
4. Understand How Your Riflescope Reticle Works
Your reticle is another important part of using a riflescope at different distances.
Some reticles provide additional reference points that can be used for elevation or windage holds. How those references work depends on the specific reticle design and whether your scope uses a First Focal Plane (FFP) or Second Focal Plane (SFP) reticle.
First Focal Plane (FFP) Reticles
In an FFP scope, the reticle changes in apparent size as you change magnification.
The reticle's subtensions, however, remain proportional to the target at different magnification settings.
This can make an FFP reticle useful when using its reference points across the scope's magnification range.
For example, the ARKEN EP-5 GENII uses an FFP reticle, so its reticle references remain consistent relative to the target as magnification changes. FFP reticles can be used like a ruler to measure the distance between your point of aim (POA) and point of impact (POI). A 1 MIL reference remains 1 MIL at low or high magnification. The reticle appears smaller at low magnification and larger at high magnification; depending on the design, some reticle features may be harder to see at lower settings.
Second Focal Plane (SFP) Reticles
With an SFP scope, the reticle remains the same apparent size as magnification changes.
However, the relationship between the reticle's subtensions and the target is tied to a specified magnification setting. If you're using the reticle for holdovers or other measured references, make sure you understand the intended magnification setting for your particular reticle. This is typically at the maximum magnification level.

Know When to Use Your Elevation Adjustment
When you move away from your zero distance, the bullet’s trajectory changes. Depending on your shooting setup, you may need to account for that change by adjusting your elevation turret or by using a reference point on your reticle.
Understanding what each turret click represents can help you make more informed adjustments.
For example, the ARKEN SH-4J GENII 6-24x50 features 0.1 MIL / 0.25 MOA turret adjustments, depending on configuration. Each click represents an angular adjustment, and the corresponding point-of-impact change depends on the shooting distance.
For example, a 0.1 MIL adjustment corresponds to approximately 0.36 inches at 100 yards and 0.72 inches at 200 yards. The same principle applies to MOA adjustments, using the MOA value specified for the scope configuration.
The key point is that a turret does not move the point of impact by a fixed number of inches. It makes an angular adjustment, so the resulting point-of-impact change increases with distance.
Before making an adjustment, always check the specifications of your particular ARKEN riflescope and confirm whether your scope uses a MIL or MOA configuration.

If you're not familiar with MIL and MOA, our guide [MIL vs. MOA: Understanding Scope Adjustments] explains how these systems work.
Important: Distance alone does not tell you how much elevation adjustment is required. The actual correction depends on factors including your rifle, ammunition, zero distance, ballistic characteristics, and environmental conditions.
6. Dial or Hold? Understand Your Options
When you need to account for a change in trajectory, there are two common approaches.
Dial the Elevation
You can use your ballistic data to determine the appropriate elevation correction and dial that correction into your turret.
This approach can be useful when you have reliable data for your particular rifle and ammunition. As distance increases, bullet drop generally increases relative to your zero, so you may need to adjust elevation to keep your point of aim on the target. Dialing can also keep the reticle's central aiming area available for observing the target and using windage references.
Use a Reticle Hold
Alternatively, you can use a suitable reference point on your reticle instead of dialing the turret.
A reticle hold can be useful when speed matters and the required correction falls within the reticle's available references. If your reticle provides suitable subtensions and you understand how they relate to your setup, you can use the corresponding reference point as your point of aim instead of dialing the turret.
Neither approach is universally correct. Your choice depends on your scope, reticle, available ballistic data, and shooting situation.
7. Use Ballistic Data as a Starting Point
When working at longer distances, ballistic data can help you estimate the correction required for a particular distance.
A ballistic calculator takes factors into account when calculating a trajectory, such as:
-
Zero distance
-
Muzzle velocity
-
Bullet weight
-
Ballistic coefficient
-
Scope height
-
Environmental conditions
Use data specific to your rifle and ammunition to estimate the expected trajectory and elevation correction. Keep in mind that calculated results are estimates, not guaranteed points of impact.
Your actual results may differ from the theoretical model, so verify your ballistic data at the range and refine it based on observed results.
8. A Practical Example: Moving From 100 to 300 Yards
Let's put these ideas together.
Imagine your ARKEN riflescope is zeroed at 100 yards, and you're preparing to shoot at a target at 300 yards.
Here's a simple way to approach the change:
Step 1: Confirm Your Zero
Start by making sure your rifle is still properly zeroed at 100 yards.
Step 2: Choose Your Magnification
Increase magnification as needed to get enough target detail while maintaining a usable sight picture.
The appropriate setting will depend on the size of the target and your shooting conditions.
Step 3: Check Your Ballistic Data
Use data specific to your rifle, ammunition, and zero to determine the expected correction for 300 yards.
Step 4: Decide Whether to Dial or Hold
Depending on your scope and reticle, you may choose to dial the elevation correction to move the reticle to the new point of aim or use an appropriate point along the reticle as your new point of aim.
Step 5: Confirm the Actual Point of Impact
Make the adjustment and verify the result at the new distance.
If the actual impact doesn't match your expected result, use the difference to refine your data. With an FFP reticle that has marked subtensions, you can measure the distance between POI and POA, then use that measurement to inform a turret adjustment or reticle hold.
Remember: There is no universal "300-yard adjustment." Even two different rifles using the same ammunition can require different corrections at the same distance.
9. Common Riflescope Adjustment Mistakes to Avoid
Always Using Maximum Magnification
Maximum magnification isn't always the most useful setting.
If your field of view becomes too narrow or target acquisition becomes difficult, reducing magnification may give you a better overall sight picture.
Assuming Distance Alone Determines Your Adjustment
A target at 300 yards does not automatically require one specific elevation correction. Bullet velocity and other ballistic factors affect trajectory, so different loads can require different corrections at the same distance.
Your ballistic setup matters.
Ignoring Your Reticle Design
FFP and SFP reticles behave differently as magnification changes.
If your reticle has subtensions, know how your particular reticle is designed before using it for holds or corrections.
Mixing MIL and MOA
MIL and MOA are different angular measurement systems.
Make sure your ballistic data and scope adjustment system use the same units. If someone is helping you spot your POI, their corrections must use the same system as your scope and reticle. MIL corrections won't translate directly to a scope using MOA.
Relying Entirely on a Ballistic Calculator
Ballistic calculations are useful, but actual shooting results provide an important check.
Confirm your data whenever practical.
Do Not Change Too Many Variables at Once
If you're trying to understand a change in point of impact, keep your setup as consistent as possible.
Changing ammunition, zero, magnification, and other variables at the same time can make it difficult to determine what caused the difference.
Get to Know Your ARKEN Riflescope
Using an ARKEN riflescope at different distances doesn't require memorizing a complicated set of settings.
Start with a confirmed zero. Choose magnification based on the sight picture you need. Understand your reticle, know whether your scope uses MIL or MOA adjustments, and use ballistic data specific to your setup.
Most importantly, confirm what actually happens when you move to a new distance.
The more familiar you become with your rifle, ammunition, and scope, the easier it becomes to make adjustments with confidence.
Know your setup. Use the features that matter. Confirm the results.
