Want to instantly measure your shot groups with precision, just by using your smartphone? You can do this with the excellent, proven Ballistic-X program, which has versions for both Android and Apple (iOS) devices. Ballistic-X is handy, relatively precise, and easy to use. But it does cost $7.99.

If you want to try a group measuring App that is completely FREE, there is a good new Android App called My Shooting from Bokili Production software. This new My Shooting App was created by a match shooter in Europe. It actually offers some cool features not available with most other group-measuring Apps. For example you can measure and display MULTIPLE group sizes on the same screen and keep them all in one file so you can quickly compare group size. There is a radius value in addition to group size (center to center of farthest shots). The App also includes an INFO box where you can display rifle type, sights/optics, ammo caliber, target distance, date, and even wind values and temperature. That’s handy.

FREE APP — You can download My Shooting App from the Google Play Store for FREE. Sorry there is NO Apple iOS/iPhone version at this time.

My Shooting lets you take images and perform all measurements internally within the application. To use the My Shooting App, simply take a photo of the target(s) with your smartphone. Then enter a known dimension on the target (such as the diameter of 10 Ring). Next click a circle on each shot-hole, and then mark the aiming point on the target. The App then does all the calculations, listing the group size in inches or mm (as you prefer). The App also list the Radius of the group, and the group’s Point of Impact (POI) separation from the Point of Aim.*

NOTE: If you enter bullet caliber and target distance, My Shooting App will display the angular measurement in MOA or Milliradians. That can be VERY handy when shooting at long ranges. The “smart” App shows the group’s actual dimension PLUS the equivalent MOA or Mils at your shooting distance. The App lets you choose either imperial (inches/yards) or metric measurements (millimeters/meters).

Bojan Radović, the creator of My Shooting App, is a shooter himself and an AccurateShooter.com visitor. He told us: “I am a shooter and a programmer from Europe. I recently created an Android App that works very precisely to measure a group of hits. The application is free!” NOTE, however, like most free Apps, the My Shooting App does contain small advertisements.

Many guys getting started in long range shooting are confused about what kind of scope they should buy — specifically whether it should have MIL-based clicks or MOA-based clicks. Before you can make that decision, you need to understand the terminology. This article, with a video by Bryan Litz, explains MILS and MOA so you can choose the right type of scope for your intended application.

This March-FX 5-40x56mm Tactical FFP scope features 0.05 MIL Clicks.

You probably know that MOA stands for “Minute of Angle” (or more precisely “minute of arc”), but could you define the terms “Milrad” or “MIL”? In his latest video, Bryan Litz of Applied Ballitics explains MOA and MILs (short for “milliradians”). Bryan defines those terms and explains how they are used. One MOA is an angular measurement (1/60th of one degree) that subtends 1.047″ at 100 yards. One MIL (i.e. one milliradian) subtends 1/10th meter at 100 meters; that means that 0.1 Mil is one centimeter (1 cm) at 100 meters. Is one angular measurement system better than another? Not necessarily… Bryan explains that Mildot scopes may be handy for ranging, but scopes with MOA-based clicks work just fine for precision work at known distances. Also because one MOA is almost exactly one inch at 100 yards, the MOA system is convenient for expressing a rifle’s accuracy. By common parlance, a “half-MOA” rifle can shoot groups that are 1/2-inch (or smaller) at 100 yards.

What is a “Minute” of Angle?
When talking about angular degrees, a “minute” is simply 1/60th. So a “Minute of Angle” is simply 1/60th of one degree of a central angle, measured either up and down (for elevation) or side to side (for windage). At 100 yards, 1 MOA equals 1.047″ on the target. This is often rounded to one inch for simplicity. Say, for example, you click up 1 MOA (four clicks on a 1/4-MOA scope). That is roughly 1 inch at 100 yards, or roughly 4 inches at 400 yards, since the target area measured by an MOA subtension increases with the distance.

MIL vs. MOA for Target Ranging
MIL or MOA — which angular measuring system is better for target ranging (and hold-offs)? In a recent article on his PrecisionRifleBlog.com website, Cal Zant tackles that question. Analyzing the pros and cons of each, Zant concludes that both systems work well, provided you have compatible click values on your scope. Zant does note that a 1/4 MOA division is “slightly more precise” than 1/10th mil, but that’s really not a big deal: “Technically, 1/4 MOA clicks provide a little finer adjustments than 1/10 MIL. This difference is very slight… it only equates to 0.1″ difference in adjustments at 100 yards or 1″ at 1,000 yards[.]” Zant adds that, in practical terms, both 1/4-MOA clicks and 1/10th-MIL clicks work well in the field: “Most shooters agree that 1/4 MOA or 1/10 MIL are both right around that sweet spot.”
