There are several options and types of rifle scopes in the market to purchase from. In some instances, there will be either adjustment choices in MOA and MRAD. Your reticle and one of the settings will determine the correction to the width and height to obtain a nice target shot. It is possible to use both adjustments, but each type requires a specific way to calculate.
When we’re talking about the MRAD vs. MOA dilemma, it’s important to note that both the turret and reticle are the main components of a proper scope alignment.
The reticle can either be a red dot or crosshair which offers an aiming point accurately within a scope’s FOV. Reticles are laser etched on glass directly or curated from wires. They’re advanced currently to compensate for both windage and bullet drop, aka Bullet Drop Compensating scopes.
On the other hand, Turret is a scope’s twistable knob that is utilized to adjust reticles. The main turret types are ballistic turrets and target ones. They were initially designated to aid in accurate long-range targets. With external MOA markings, utilizing tall turrets helped shooters with fine adjustments when lowering or raising bullet impact. However, ballistic turrets came in 100-yard type increments offering speedy and simple ways of adjusting the bullet trajectory.
When zeroing in on optics, turret and reticle are in unison used to achieve high precise long-range shots. This is inclusive of purposefully turning the turrets to move the crosshair in various directions. Today’s scopes provide accurate and high magnification, measuring capabilities as well as better clarity. Nonetheless, with various scope products that are complex in the current market, it might be a fret to understand and even use the measurements and marks accurately. Therefore in this article, we will be discussing the main scope alignment systems, MRAD and MOA.
How Does a Long Range Rifle Scope Work?
Long range types of scopes can be used with both various reticle and turret types. Standard rifle scopes are manufactured with reticles, which are designated specifically for close turrets and range shots.
This enables a shooter to adjust the reticle’s position by removing a turret cap firstly then using tools to adjust its placement.
Nonetheless, long range scopes feature quick-adjust turrets and range finding reticles to help them adjust the reticle’s position and then return it to its initial aim by pressing down the turret’s top. Unlike standard rifle scopes that are best meant for shooting at stationary targets, tactical rifle scopes are perfect for long-range targets that require rapid scope adjustments. It is also noteworthy that even with a tactical rifle scope; you will need to choose a scope that can accurately measure angles in MRAD or MOA.
What is MOA?
This is an initial for minutes of angle that’s based on minutes and degrees. It is typically an angular measurement. There are 360 degrees in one circle, and each degree is 60 minutes totaling 21600 degrees, meaning that an MOA basically is a 1/60th of one degree. This angle measurement type is utilized to correctly calculate the bullet impact’s correction and distance to a specific target.
With 1 MOA you often make calculations at 91.4 meters (100 yards). However, you may need to rely on 1.05 MOA at 100 yards. You can use this calculation to 100 yards only. Longer distances will result in a 5% off, consequently leading to a miss.
|100 yards (91.4 m)||1/4 MOA = 0.26″ of 0.66 cm|
|100 yards (91.4 m)||1 MOA = 1.05″ of 2.67 cm|
|200 yards (182.8 m)||1/4 MOA = 2.1″ of 1.33 cm|
|200 yards (182.8 m)||1 MOA = 2.1″ of 5.33 cm|
|300 yards (274.3 m)||1/4 MOA = 0.79″ of 2.00 cm|
|300 yards (274.3 m)||1 MOA = 3.15″ of 8.00 cm|
