Calculating Bullet Drop. For the long pass, you’re going to give the ball a higher angle in order to reach the receiver. Imagine that you’re using a flashlight that casts light in a very tight circle. The reason why this is important is because we need to know the limitations of the rifle that we are using. In the course of perfecting your shooting accuracy, you will hear the word MOA. Here are the actual conversions that will hopefully illustrate what we’re talking about: Inches of Adjustment Inches of Spread → MOA Adjustment, MOA AdjustmentScope MOA Increments → Clicks. Each time you move the turret, it clicks, and the lines below the numbers guide you. So, 16 Clicks on the scope will compensate for the 24 Inches of adjustment at 600 yards. Download our FREE ebook with 250 reticle patterns from the top manufacturers. This is the same concept as MOA, but it is a courser unit of measurement (at 100 yards a MIL is 3.6 inches) and less commonly used. The Relationship between MOA and Distance Riflescopes come with the following specifications: You will need a data book, and be apt and patient for taking notes. …so we take a shot to determine the inches of adjustment we need to make up. Let us now think about MOA for the rifle. Now, what are those calculations? In practice, it just means moving the dial with clicks in the negative direction as opposed to a positive direction. I can't recall how many... 3920 Wood Duck Drive Pelkie, MI You may notice that you are shooting dead on at closer targets like about 200 yards away. So on a mil dot scope 1 mil equals 3.6 inches at 100 yards. We put the crosshairs on the target, fire and notice that our shot is, “Wait wait wait!!! MOA is not dependent on distance. In simple terms, a zeroed rifle means that if you take a shot at 100 yards, your bullet will hit exactly where the crosshairs are located. If that flashlight cast its light at 1 MOA, then at 100 yards the light would only illuminate a 1-inch circle. At 200 yards it would illuminate a 2-inch circle, 300 yards a 3-inch circle, and finally at 1000 yards, a 10-inch circle. Required fields are marked *. Shooting in the wind is never fun, well it can be fun once you know how to do it. MOA is so handy because 1 MOA spreads at right around an inch at 100 yards, and the measurement is consistent for every hundred yards. Apply this rule: 1 minute (or 1 MOA) is one inch at 100 yards. I need to learn how to calculate the MOA drop for a .308 I know a minute of angle at 100 yards is 1 inch and 2 inches at 200 and so on but how to I calculate what the drop is for the .308 caliber from 100-1000 yards so I know how many clicks to scope in … You’ll need to do a simple transition to calculate the MOA in accordance with the magnification.”. Suppose the bullet drop is 40 inches from the target as you shoot 400 yards away. For example, if you had a rifle scope that had “positive tracking” (that is a whole other story in itself) and wanted to take a long-range shot…. Designed by Elegant Themes | Powered by WordPress, I think we can agree that if you’ve ever done any research on shooting better, you’ve run into something called, In this post, we’re going to show you what that formula is, explain Minutes of Angle from the ground up, and show you how you can confidently use minutes of angle. Turrets are a critical component to the rifle scope. You were probably too busy making amateurish attempts at sexting Becky in the front row. Here is more in-dept guide on using the mil-dot reticle for measuring distance. In this post, we’re going to show you what that formula is, explain Minutes of Angle from the ground up, and show you how you can confidently use minutes of angle and consistently hit your target each and every time. You can do this same simple calculation for any distance and nail your target. Think about clicks in terms of a simple number line with positive and negative numbers. Most scope manuals will give you an idea of the scope MOA at one magnification or another. Now, let’s say we want to shoot something at 200 yards. Mounting and zeroing a scope can either be a nice and easy day with plenty of time shooting and scoring bullseye, or it can... To be a precision shooter you must of course master the rifle, but you’ll also need to use a bit of math, and hope for a little luck. Trijicon ACOG 4×32 Review Through The Eyes Of US Marine. Here, a minute refers to 1/60th of a degree. It will a produce a line graph showing the bullet drop and flight path of the bullet. So you are asking, what is MOA? Let’s say you have a scope that compensates for MOA in 1/4 MOA per click, and we already have our scope zeroed at 100 yards. Understanding the capabilities of the rifle will help you understand your maximum effective range. In this case, we take a shot and have 1 inch of adjustment. 6 inch spread1/2 MOA = 1200 Yard Effective Range. You can refer to the chart above. …be sure not to conflate the two into the same measurements. shortcode: "wp", Don’t miss another shot this hunting season. 6 inch spread / 3 MOA = 200 Yard Effective Range, In this case, the rifle would only be effective for deer at 200 yards (because that would be a 6-inch group.). Here is how to calculate the MOA adjustments we need for the 40-inch bullet drop: Number of the bullet drop inches / MOA inches at the given distance = MOA needed. How do we know what our effective range is? This calculator will produce a ballistic trajectory chart that shows the bullet drop, bullet energy, windage, and velocity. After we just took (and nailed) our last two shots, let’s say our next target is now at 25 yards. The rest of what we’re talking about is getting into the nuts and bolts of how to calculate minutes of angle. As you can see, the calculations help you aim better as opposed to complicating the aiming setup. Look at the circle. Standard Ballistics Calculator. If you, or someone you know, enjoy being difficult, by all means, use the exact inches of spread, but we’d recommend using the estimated inches of spread. Your email address will not be published. Let’s say after hitting our 200-yard shot, we want to take a 600-yard shot. Something else important is calculating bullet drop on an optic when you do not have a specific bullet drop compensator built into your rifle. All, knew what I wanted, just wasn't asking the right question. For those who know it, they realize that some calculations are crucial if you want to improve on accuracy. For our case above, if you have ¼ MOA adjustments on your scope, to get to 10 MOA will require 40 clicks. Michigan Center, MI 49958 Having figured out that, we can now deduce a formula to help us calculate faster. Save my name, email, and website in this browser for the next time I comment. This is where you hear talk of a one MOA rifle (or better). So let’s fill in the equation to determine our clicks. In this case, the effective range of the rifle is 1200 yards. Make sure you know the distance you are shooting from and the bullet drop. When you reduce the magnification level to 9 the MOA would change to 5 MOA. In that case, we’d have to move to the left of zero on the number line (into the negative numbers) in order to compensate. That is where MOA comes in as a useful measurement. IN A HURRY? (400 x 1.047) / 100 = 4.188 which translates to 4.2 inches. Effective Range = ?????? …and it will hit the target in a spread of inches according to its MOA. (ie., a .50 caliber bullet … to do with a minute of time that has elapsed. Sticking with our example of wanting to hit that 800-yard target and accounting for 163.53 inches of bullet drop, let’s do the long walk through the math to calculate how many MOA that is. Here’s an example of the two concepts we just discussed, i.e. Think about the minutes in an hour. When you reduce the magnification level to 9 the MOA would change to 5 MOA. So in terms of 1/4, it’d look like this in your head: So, if the scope increments were in terms of 1/8 we’d multiply the 3 MOA by 8. Since most rifle ranges are spelled out in hundreds, MOA is very handy to understand and know. You’ll need to do a simple transition to calculate the MOA in accordance with the magnification. Typically MOA is correct at the highest magnification setting of the optic. consistently hit your target each and every time. Why is there a positive sign next to the clicks?”. That’s what we adjust a long range target scope on a rifle using the elevation turret. Let’s think about deer lungs as a target. Then factors such as the shooter's skill, and the wind conditions come into play, to determine the final precision of shots on target. As it travels further, the force of gravity becomes larger hence the decrease in velocity. target: "#hbspt-form-1604486152000-3013825407", If you have any questions or need assistance: 1-800-4VORTEX ext 5 ...

That’s the portion we are talking about here. Sorry boys I can't work this out! We now have all the ingredients we need to do our equation. Calculating the Bullet Drop We must compensate for this drop by using minutes of angle. This is certainly a timely method and requires a lot of ammunition and note taking. In the real world, external forces between the muzzle and target affect bullet trajectory. Let’s use the analogy of a flashlight to illustrate what I’m talking about. Are you going to be able to gun it to the receiver in a straight line? thats what i'm after, how to calculate bullet drop in inches into moa clicks on the scope.. regards griff. With the 5 yard pass, you can basically gun it to the receiver and the ball will travel in a straight line. The distance that you’re shooting from is what determines how many clicks the scope will need to be moved in order to compensate for bullet drop. Formula to Calculate 1MOA size at any distance: Distance to the target (yards) /100 = inches per MOA for the distance.
