3 moa vs 6 moa
A mil reticle with mil turrets, an MOA reticle with MOA turrets, and a mil reticle with MOA turrets. There are several options to choose from. Modern scopes adjust in 1/4 MOA increments, meaning you will need to bring your crosshairs right 4 clicks of the wheel to hit dead center on your target. Just as with a mil-dot scope, you'll need to know how far each adjustment of the wheel on your turret moves your crosshairs. This means we're off by 1 inch, making this an easy adjustment. Here is a quick formula to find your MOA correction when shooting at distance.įor this example, we're sighting our rifle in at 100 yards and are hitting the target dead on top-to-bottom, but we are hitting at the first dash on the left of the crosshairs. While there is a standard known as Shooter’s Minute of Angle (SMOA) where that value is a true 1 inch between dashes, 1.047 inches is so close to 1 inch that it can just be rounded down. Using the previous example of 100 yards, the distance between these dashes represents a height of 1.047 inches on your target.
When looking through your MOA scope, you'll typically see your crosshairs, along with lines or dashes on both the vertical and horizontal axis. Just like an hour, a degree is made up of 60 minutes. Minutes are just a smaller measurement of a degree. Minutes of angle are a bit easier to understand than mils, though. However, they differ in size, with mils being the larger of the two. MOA stands for "minute of angle." A minute of angle is also a measurement of an angle within a circle, just as milliradians are. Most modern mil-based scopes adjust in 0.1 mil increments, meaning you will need to bring your crosshairs down 10 clicks of the wheel to hit dead center on your target. You'll need to know how much of an adjustment is made to the crosshairs when turning the dial on your turret. If you are shooting at a target 100 yards away, and the bullet is striking the target centered left-to-right but impacts at the first dot above the crosshairs top-to-bottom, you're hitting your target 3.6 inches high.
3 MOA VS 6 MOA SERIES
When looking through a mil-based scope, you will see either series of dots or hash marks on either side of the vertical and horizontal crosshairs.Ī quick word on adjusting your scope while sighting it in. To understand how a milliradian is measured, some trigonometry is required, but that is beyond the scope of this article. A milliradian is a measurement of an angle within a circle. It does not mean "military," though that is a common misconception. They’re most popular for long-range competition shooting. This is generally referred to as Christmas-tree-style reticle and can be found in both mils and MOA. So, what are mils and MOA? Reticles come in all shapes and sizes. A typical adjustment on an MOA based turret represents 1/4 MOA (more on this to come). A typical adjustment of 1 click on a mil-based turret represents one-tenth of a mil (more on this to come). There are two systems of measurement that scope makers use when designing reticles and turrets: mils or MOA. Now that you know the parts of a scope and what they do, here comes the tricky part. You'll use these to adjust the scope's reticle up or down and left or right so that it coincides with where your gun is shooting. They're the knobs on the top and the side of the scope. The final pieces of the scope you should know about are the turrets. You will see a crosshair, and in some scopes, integrated into this crosshair, you will see a series of dashes or dots going up and down, left and right. On the surface of one of the pieces of glass inside the scope is the reticle. Some scopes will have fixed magnification while others will be adjustable. These provide your view through the scope as well as your magnification. The scope consists of a body, or tube, containing several pieces of glass. There are a few important parts to know about when it comes to choosing scopes. We've all been there, and we've been just as confused.
3 MOA VS 6 MOA HOW TO
The shop employee says, "What kind of scope are you looking for?" but you're not sure of how to reply! What's out there? Each scope has a bunch of numbers on the box. You've bought your firearm you've saved up to buy a scope you walk into a retail store and you start looking at options.
