CATS Targets

CATS Calibration Targets are patented targets designed to allow the user to validate the tracking of their turrets and identify if the user is canting their rifle. Designed to be used at 100 yards, you're able to collect valuable data to improve your accuracy without the need for extended ranges. 

The same target can be used for MOA or MRAD scopes as both are marked on the same target.

NOTES: 1. You must accurately zero your rifle prior to using this target. 

             2. Ammunition that consistently shoots ½ MOA or better is required.

             3. You must shoot using good marksmanship and from a repeatable position or you will get invalid results. 

             4. Test should be run 3 times to validate results. 

  1. Target Mounting - Mount this target to a stiff backing, ensuring no folds in the target. 
  2. Target Range - Place the target approximately 100 yards down range, ensuring the target is perpendicular to the ground. 
  3. Rifle Position - Position yourself perpendicular to the target and ensure the horizontal and vertical crosshairs on your reticle (MOA or MRAD) line up with the lines (MOA or MRAD) on the target, i.e. 10 MOA on your reticle lines up with 10 MOA on the target. Your reticle crosshairs MUST align with the target lines for the target to work. 
  4. Hold the center of your reticle crosshair on the center of the “0” line at the bottom of the target, ensuring your primary horizontal stadia on your reticle aligns with the “0” line and shoot, ensuring a hit in the white box on the “0” line.  
  5. Dial 1 MOA or MRAD on your elevation turret, continue to hold the center crosshair on the “0” line and take a shot, then dial 2 MOA or MRAD, etc. until you reach the top of the target, taking a shot at each increment. 


Use of firearms can result in serious injury or death. Please observe the following firearm safety rules at all times:

1.     Treat every gun as if it were always loaded, even if you have verified that it is not.

2.     Never allow the muzzle of a firearm to point at anything that you do not intend to shoot.

3.     Keep your finger off the trigger until you are ready to shoot.

4.     Be sure of your target and what is beyond.  You must be absolutely sure your backstop/berm is adequate to stop any angle of fired projectiles when using targets of any design.

HORUS Vision accepts no responsibility for errors in the information presented herein or for accidents, injuries, damage, or any other problems which might arise as a result of your use of the information contained on this target and expressly disclaim all liability for injuries, death, and damages, whether direct, incidental, consequential, punitive, or otherwise.

NOTE: We suggest running three tests and getting consistent results to ensure any conclusions are based on accurate data. 


The above results indicate a properly performed test, using a properly functional scope and level rifle setup.


#1 - The straight line between impacts indicates the rifle is likely canted to the left.

#2 - The arched line betwene impacts indicates a potential issue with you're scope's ability to dial elevation without causing a shift in windage.

#3 -The impacts missalignment with the target indicates a potential issue with your elevation tracking.

Q: I'm not at exactly 100 yards when my reticle lines up correctly with the taget, why is that?

A: There are several potenial causes or combinations of things causing this issue. Your rangefinder may be off, you may have not measure with a tap in a perfectly straight/level line, your scope may be slightly off due to manurfacturing tolerences. The most important thing to ensure valid data is that your reticle subtensions match the target.


Q: If I am working in mils, do I need to range and shoot from 100 meters?

A: No, the target is set up to only be shot at 100 yards. Since it is an angular measurement, it doesn’t matter if your shooting MILS or MOA.


Q: What power should I have my scope when using the target?

A: With a first focal plane scope it doesn't matter but it should be enough power that allows you to see the target well enough to aim precisely and still have low enough power to align my reticle as high up as possible with the black line at the bottom of the target. With a second focal plane scope you should use the power where your reticle suptends correctly. 


Q: Can I test my scope turrets even if it does not have a Horus Reticle?

A: Yes, it will be extremely important to at exactly 100 yards to produce valid results, so we sugguest you use a steel measuring tape and very carefully measure. 


Q: Some of my impacts were high then as I went higher up they hit low. What could be causing that? 

A: This is most likely a result of parallax not being adjusted correctly. If you move your head up and down as you aim and the reticle moves away from your aiming point, you have parralax set incorreclty and depending on where you place your eye for each shot, the impact wil vary. You cannot rely on the number on the parralax knob, you must adjust and then visually verify through the scope that it is adjusted correctly to remove parallax.
