Indoor Ballistic Setup: Understanding Zero, Alignment, and DOPE Application
Ballistic dry-fire training inside LaserHIT follows real-world shooting logic. However, one key difference often causes confusion during initial setup: indoor distance.
This guide explains how to correctly prepare your rifle, align your system, and apply your DOPE so LaserHIT ballistics behaves exactly as intended.
Step 1. Create a Temporary Indoor Zero
Your rifle is typically zeroed at 100 yards.
At an indoor distance of approximately 8 yards, that same zero will not align with the target. The laser will impact significantly below your point of aim.
To correct this, you must establish a temporary indoor zero.
Without using the LaserHIT app:
Adjust your scope turrets until the laser consistently hits the center of the target at your indoor distance.
This becomes your temporary zero reference.
Example:
If your indoor zero requires 20 MOA adjustment, that becomes your baseline.
Now apply your real DOPE on top of this value.
Example:
At 500 yards:
Drop = 6.3 MOA
Wind drift (10 mph) = 2.5 MOA
You dial:
20 MOA + 6.3 MOA = 1.3 MOA total elevation
Wind remains a hold.
This is the key concept:
You are not replacing your zero.
You are stacking your real DOPE on top of your indoor zero reference.
Step 2. Align Your Scope with the Target Reference Reticle
LaserHIT ballistic targets include reference reticles for a reason.
They allow you to verify correct geometric scaling.
Procedure:
Align your scope reticle center with the zero reference on the target.
Then check a known reference point, such as 20 MOA.
If your scope reticle is below the 20 MOA mark -> you are too far -> move slightly forward.
If your scope reticle is above the 20 MOA mark -> you are too close -> move slightly backward.
Adjust in small increments.
Even a few inches will affect ballistic accuracy.
This step ensures that your indoor setup matches the intended ballistic scaling.
Step 3. Apply Your DOPE Correctly
Before starting the drill, confirm the ballistic trajectory inside your Firearm Profile.
Go to:
My Ballistic Presets -> select your preset -> Review & Edit -> Trajectory
Tap the Settings icon and switch Drop/Drift units to inches -> return to Trajectory.
On the graph, move the target to the right and verify the first two trajectory points:
• sight height offset
• 100-yard zero point
These two reference points confirm that your trajectory has been imported and interpreted correctly.
After verification, switch the units back to match your scope (MOA or MRAD).
Once your system is aligned, your ballistic workflow becomes identical to real shooting.
Dial elevation based on your DOPE.
Apply wind hold based on the current condition.
The drill applies a crosswind between 0 and 10 mph for each stage.
Your process remains the same as in the field:
Read the wind -> Calculate the hold -> Execute the shot
Step 4. Express Setup Checks
Before starting your session, confirm the following:
Lighting
Ensure even lighting across the target.
Avoid overexposed (bright/red) areas, especially along the bullet path.
Phone position
The target and reset mark should fill the phone screen from edge to edge.
Use zoom if needed.
Distance
Place the phone approximately 2–3 feet from the target.
Target visibility
The phone must clearly see the target, but it must not obstruct your view through the scope.
Common Source of Errors
If your drop or wind does not match expectations, the cause is usually:
• incorrect indoor zero
• incorrect distance to target
• misalignment with reference reticles
• incorrect sight height value
• incorrect units (MOA vs TMOA)
In most cases, the issue is not the ballistic profile itself, but a setup detail that needs adjustment.
Before You Go
Ballistic training inside LaserHIT is built around real shooting logic.
Your rifle setup remains the same.
Your DOPE remains the same.
Only the distance is reduced and precisely scaled for indoor use.
Once the setup is correct, the drill becomes a true repetition of your real shooting process.
