Q&A for How to Calculate Distances With a Mil Dot Rifle Scope

Mil stands for milliradian, so to get it to radians, you must multiply by 1000.

Bullet weights and loads vary, so you might need to do a little of your own math and keep a record for height adjustments.

Yes, if your mobile phone has a calculator, and you have the formula. Calculator apps are also available and are free to download on Google play and in the Apple play store.

For the calculation to work at all zoom settings (magnification), a first focal plane (FFP) reticle is required. With a second focal plane (SFP) scope, the reticle markings are only accurate at one magnification setting, which varies by scope model.

I've never seen an optic that uses 1/4 mil clicks. Your Leupold is likely in 1/4 MOA clicks, not mil. Your Schmidt and Bender is likely in mils, and uses 0.1 mils per click. These are completely different units of measurement. MOA tends to work easier with imperial units, as 1 MOA at 100 yards is very close to 1" (meaning for your Leupold 1 click at 100 yards will move about 1/4"). Mils tend to work easier with metric, as 1 mil equals 10 cm at 100 meters. So each click on your S&B scope is 1 cm at 100 meters.
