I check my dope chart and see my bullet drop for that range is 3.2 inches. 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. At 900 yards, that same, mild, 10 MPH headwind or tailwind, would require a seven click correction to place our .308 bullet on center-target. The Applied Ballistics calculator steps through time. Range in 100 Yds. If you've already used an MOA scope to adjust, you can convert the figures to Mils and use them quickly without doing additional measurements. This calculator will produce a ballistic trajectory chart that shows the bullet drop, bullet energy, windage, and velocity. This angle measurement type is utilized to correctly calculate the bullet impact's correction and distance to a specific target. Sight in your rifle to hit 3 inches high at 100. Velocity estimated. Ballistic calculators have made the leap from dedicated devices to smartphone apps. Answer (1 of 5): Lots of programs and apps are available which will approximate your trajectory and needed adjustments but the only way to really know is to actually shoot at regular distances out as close as possible to the limits of the round. With the MOA and MIL systems, you correct the position of the reticle inside the scope, based on wind deflection and trajectory of the bullet at the target's distance. * Selectable drag function for ballistic coefficients calculate based upon models. Bullet drop inches / MOA inches at a certain distance = Moa needed. * Selectable output units: inches, MOA, & mils. Over 14" in drop at 300 yards according to Hornady's ballistic program using the numbers I crunched. A zero degree (flat ground) shot from the 338Edge +P at 771 yards, calls for 15 MOA up. For units of MOA, enter "1.0" and select "MOA" for the units. Now, use a similar formula to calculate the required Moa for 400 yards with a bullet drop of 40 inches. This comes from factory calculations or data on previous shots. 4DOF ® Ballistic Calculator. Now, if you were shooting from 400 yards and hitting a target 4 inches away, it means the 4 Inches distance is 1 MOA. 20 April 2007, 23:46. griff. In the case of a 22X NF scope, that setting is 22 power. Distance: 500 yards - Bullet drop = 73.0 inches - Mil adjustment = 4.1. Calculating the Bullet Drop This is the same concept with minutes of angle. However, like any other caliber at extreme long range, you need . A 28 degree shot at the same distance calls for 12.8 MOA up, a difference of over 17 inches at that distance. Based on ballistic coefficient of a bullet, Muzzle Velocity, Height of Sight, Range yards zeroed, wind speed, this app estimates the bullet drop and wind drift. Therefore, 40 inches low / 4 inches (1 MOA is 4 inches at 100 yards) = 10 MOA adjustments on the scope. The farther away you are from a target, the lower your bullet might strike from where you intentionally aim. They are useful and quick to action when working from a vehicle. thats what i'm after, how to calculate bullet drop in inches into moa clicks on the scope.. regards griff. Thus, dial six clicks on a ¼ MOA increment scope, or hold 1.5 MOA into the wind - at 700 yards that would be 10-1/2 inches. It give them an idea what various cartridges and load recipes will do at the range. For instance, your target is 300 yards away, and there's a 10 MPH wind: 3 x 10 = 30/15 = 2 MOA. In the real world, external forces between the muzzle and target affect bullet trajectory. For a rifle that has a 2 MOA, the conversions are very simple: 100 yards * 2 MOA → 2-inch spread of each other, 500 yards * 2 MOA → 10-inch spread of each other, 1000 yards * 2 MOA → 20-inch spread of each other. Zero Range (yards) Must be in increments of 50. 308 Winchester (7. Using an MOA Reticle ("Hold Over") Many rifle scopes contain "hold-over" marks, or tick marks that measure MOA vertically and horizontally. Convert the MOA measurements to Mils, divide the MOA by 3.438. Think in MOA and not in "clicks" on your scope. As far as I know, 1 million sizes for 500 yards is 18 inches. The trajectory adjustments necessary are very easy to remember. Things like muzzle velocity, bullet type, and altitude will affect how quickly a bullet drops as it flies downrange. For example: 1/4 MOA at 100 yards = 1/4 inch at 100 yards. The main problem is that BDC reticles offer a generalization of bullet trajectory and can only estimate bullet drop in specific circumstances. This is based on the distance to the target, compared to the distance the rifle was sighted in for. 1 MOA is equal to basically a 1″ inch circle at 100 yards away from the gun. Thus, 70"/18" = 3,89 mils that I need to adjust for bullet drop. All, knew what I wanted, just wasn't asking the right question. 308 Norma Magnum is a rare chambering, retaining a small following but with a great deal of respect.
