Reticle Options of Vortex Razor HD 5-20×50

Multiple reticle options are available with Vortex Razor HD 5-20×50 and in this article we will discuss on them so that you can select the right reticle with the riflescope. Three reticles can be used with this Vortex scope and they are EBR-3 reticle, EBR-2B reticle, and EBR-1 reticle.

1. EBR-3 Reticle

This reticle is very popular among leading precision rifle shooters. It is a mil-based one and comes with various modern features. Inspite of the presence of modern features, this reticle is simple and has a uncluttered feel. Though EBR-3 reticle comes with 0.5 mils primary subtensions, shooters can use it for precise range estimation as precise marks of 0.1 subtensions are also available. Even at lower magnification, you can acquire target quickly through this reticle because of the presence of heavy posts at 3, 6, and 9 o’clock positions.

MRAD specifications on the reticle is kept at tightest possible tolerance as there are ultra precision laser etching on the glass reticle. With this EBR-3 MRAD reticle, you can determine windage corrections, holdovers, ranges, and moving target leads effectively. This reticle is designed in such a manner that long range shooting as well as ranging abilities are maximized. For providing shooters with the perfect balance between low light visibility and precision aiming, fine center crosshair subtensions on the reticle were carefully chosen.

EBR-3 reticle mrad subtensions in the Vortex Razor HD riflescope are located in the First Focal Plane or FFP. This helps the shooters in getting the preferred magnification range without having any effect on windage reference marks and effective holdover. If you are unaware about MRAD calculation, here is the formula for getting the right range in yards/meters.

[Target Size (Yards/Meters) x 1000] / mrads read = Range (Yards/Meters)
Or, [Target Size (Inches) x 27.8] / mrads read = Range (Yards)
For using this formula correctly, you have to know the target’s or a closely located object’s measured size.

2.EBR-2B Reticle

One of the first things you will notice in this reticle is that it has a Christmas-tree style and is available in mils (MRAD) as well as MOA.  On the drip line, a shooter will find heavier windage dot references, thereby increasing visibility at low light conditions as well as magnifications. Easy and quick referencing is ensured by the numbered subtensions on crosshairs.
One of the features of this reticle that increases precision at longer ranges is the open intersection of the crosshair. This open intersection forms a clear and small aperture, thereby increasing long range precision for the shooter. Just like the EBR-3 reticle, shooters can acquire targets easily even at lower magnification with EBR-2B Reticle because of the presence of heavy posts at 3, 6, and 9 o’clock positions.

With the MRAD or milliradian angular measurement, one thing you have to keep in mind and that is 1 MRAD is equal to 1/6283th of a circle, just like 1 degree being equal to 1/360th of a circle. If you have familiarity with MOA measurement, you can draw symmetry with it too. 1 MRAD is equal to 3.44 MOAs. At Vortex Razor riflescope, the EBR-2B reticle is located at First Focal Plane, which means a shooter can have windage reference marks as well as effective holdover irrespective of the magnification range. This feature is particularly helpful in case of high stress situations. You can calculate the range at yards, meters and inches with EBR-2B Reticle if you know the MRAD ranging formula, which is absolutely the same as given in the EBR-3 reticle section above.

In case, you are using MOA version of the concerned reticle, you must know that 1 MOA is equal to 1.05 inches at a 100 yard distance. In many cases, shooters correspond 1 inch to 1MOA. This may give you almost a correct estimation in short distance shooting, the approximation will not hold good in case of longer range shooting. This is because with every increase in 100 yards range, MOA distance estimation increases. For 100 yards, 1MOA is equal to 1.05 inches; for 200 yards, 1MOA will be 2.1 inches; for 300 yards, 1MOA will be 3.15 inches, and so on. Ranging formula in case of MOA measurement is:
Target [Size (Inches) x 95.5] / Measured MOAs = Range (in Yards)
For using this formula correctly, you have to know the target’s correct dimension.

3.EBR-1 Reticle
This reticle is a MOA based one, featuring 2 MOA subtension marks. For axis, a fine line of 0.2 MOA thickness is present. Three heavy lines of 5 MOA thickness each are present at 3, 6, and 9 o’clock positions. This helps shooters to quickly acquire target at lower magnifications too.

Selecting correct drop reference line can be done quickly here because EBR-1 reticle is scaled in 2 MOA increments. However, in this case, the shooter has to know the bullet drops in MOA. You can make faster adjustments to the elevation knob if you know bullet drops in MOAs instead of inches. This reticle type is found to be specifically effective when used for wind and moving target leads. You have to use the center horizontal crosshair’s MOA marks while estimating moving target leads.
