Mil Dot 3-9x40

Shooter $9.95

Even though it comes up second on the list, we might as well start with the highest priced paid app. It’s a whopping ten bucks. I know, half of what you pay for parking at a baseball game, but it is paid and as with most things in the Android Marketplace, you get what you pay for.

I can’t imagine that there would be any variables that you would want to include in your calculations that aren’t in Shooter. Some things I don’t even understand and I hope to do some research and experimentation to see how much of an effect they have in long range shooting.

Can you dial in all of your parameters on Shooter and take an 856 yard shot based on the calculations? I don’t know, but I do hope to test it at some point. If you want to nerd out on ballistics in the meantime, this is your app.

What makes this app different from all the others is that it not only has advanced features, it can also connect to the internal GPS of the phone to get atmospheric conditions, based on national weather service numbers, as well as being able to connect to a Kestrel weather station to get atmospheric and wind conditions live.

You can store as many rifles and bullets as you want. The only caveat, of course, is that the muzzle velocity you enter on the ammo is for a specific measured rifle, or at least barrel length, but due to variances in width, you really can’t count on a standard barrel length to shoot the same velocity in every rifle.

Please note that many of these features can be disabled by putting the app in Simple Mode. This is done from the start screen by pushing your settings button. You can also control distance units and whether your GPS inputs values by default.

The first thing you will be asked to do in Shooter is enter the details for a specific rifle and scope combination. You enter the rifle name, the twist rate and direction. On this Savage Axis I had to guess that it is a right hand twist as it was not on their website. If you have the rifle in your possession, of course, you can just look down the bore. Direction of spin is needed for “spin drift” calculation which you’ll encounter later. The elevation adjustment on most sporting scopes is MOA, or minutes of angle. Each click generally represents 1/4MOA which just happens to be ¼” at 100 yards. The sight height you get from measuring from the middle of the bore to the middle of the scope front lens. Keep in mind that not all scopes are mounted directly above the barrel. Some are mounted at an angle or to the side for various reasons. Sight offset, as used here, is the amount the sight sits to the left or right of the bore axis or centerline. Distance to the right is a positive value, to the left is negative.

The first oddball, but extremely useful, option you encounter is at the bottom of this screen. If you have a lot of experience with your scope and you know that the clicks are not 1/4MOA, you can input the actual value here.

For my data tests, I used the .30-06 Savage Axis that we saw all the way back in the out of the box MOA article.
