The science of ballistics is not as simple as many would make it seem.\u00a0 What a bullet does in flight can vary due to factors you would never think possible.\u00a0 Modern ballistics calculators, available as hand held units in the several hundreds of dollars, have been around for some time. \u00a0With the advent of smart phones, you no longer need a separate hand held calculator (unless you\u2019re in a situation where you need the physical toughness of the unit itself). <\/p>\n

The problem is, all of the name brand phone calculators were developed for the Apple Iphone, which means if you are running the Android operating system from Google, you can’t use them.\u00a0 Run a search in the Android Marketplace for \u201cballistics calculators\u201d and you\u2019ll find some free apps and some paid apps. \u00a0I decided to download several of them and see what the differences are, and if they actually work.<\/p>\n

Please excuse the screen capture pictures for this article.\u00a0 Android has a funny quirk that I hope they cure in future editions: \u00a0None of the screen capture apps work on a phone that hasn’t been what is called \u201crooted.\u201d\u00a0 To do this takes yet another app that is high risk. \u00a0It allows you to take over your phone, or jailbreak it as they say with the Apple phones, but you can seriously mess up your phone. \u00a0I have chosen to not \u201croot\u201d my phone yet, so the pictures of the screens were taken with a regular camera and it had a hard time dealing with the focus and luminosity issues.<\/p>\n

The lack of screen capture plays an important role with Android when it comes to programs like these. \u00a0Only one of the applications exports a range card, so for the rest you will be entirely dependent on using the application in the field or on the range, on the phone itself. \u00a0They don’t depend on phone lines, but if you kill your battery playing Angry Birds or using your GPS, you’ll be out of luck when you get to the range.<\/td>\n

\"Android <\/p>\n

The Android Marketplace offers both free and paid apps for ballistics. Some are great, some not so great. <\/em><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

 <\/p>\n\n\n\n
\"\"Shooter $9.95<\/strong> <\/p>\n

Even though it comes up second on the list, we might as well start with the highest priced paid app.\u00a0 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.<\/p>\n

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.<\/p>\n

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.\u00a0 If you want to nerd out on ballistics in the meantime, this is your app.<\/p>\n

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.<\/p>\n

You can store as many rifles and bullets as you want.\u00a0 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.<\/p>\n

Please note that many of these features can be disabled by putting the app in Simple Mode. \u00a0This is done from the start screen by pushing your settings button. \u00a0You can also control distance units and whether your GPS inputs values by default.<\/p>\n

\n\n\n\n
\"editfirearm1\"<\/a><\/td>\nThe first thing you will be asked to do in Shooter is enter the details for a specific rifle and scope combination.\u00a0 You enter the rifle name, the twist rate and direction. \u00a0On 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. \u00a0Direction of spin is needed for \u201cspin drift\u201d calculation which you\u2019ll encounter later. \u00a0The elevation adjustment on most sporting scopes is MOA, or minutes of angle. \u00a0Each click generally represents 1\/4MOA which just happens to be \u00bc\u201d 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. <\/p>\n

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.<\/td>\n

\"\"<\/a><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n
\n\n\n\n
\"\"<\/a> <\/p>\n

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.<\/td>\n

\n\n
\n\"\"<\/a>\n

From there it will ask you a manufacturer.\u00a0 With Hornady, the bullet is printed on the box. \u00a0Federal generally has a manufacturer and bullet listed. \u00a0Winchester also does this. \u00a0Each bullet has a name. \u00a0For this I used the Hornady 150 grain GMX bullet. The bullets where you see \u201cLitz\u201d in parenthesis are based on actual test data by Bryan Litz, author of Applied Ballistics for Long Range Shooting<\/a>, and one of the developers of Shooter.<\/p>\n<\/div>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n

\n\n\n\n
\"\"<\/a><\/td>\n\n
\n

Once you pick from the bullet library, the app will fill in the fields for that bullet.\u00a0 The only one missing for the Hornady 150 grain GMX bullet was length, which I guessed at as 1 inch. \u00a0I didn’t pull a bullet to measure and the data wasn’t on the Hornady website or on the box.\u00a0 Muzzle velocity (MV) is preferably something you measure with a chronograph if you want your results to be valid. \u00a0\u00a0I plugged in the listed velocity for Superformance.\u00a0 The MV Variation field is for those who rigorously test velocity with one or more chronographs using the ammunition at varying temperatures. \u00a0This would be the average spread based on temperature and percentage error.<\/p>\n

The Powder Temp field would be the temperature of the powder at base velocity. \u00a0Zero atmosphere refers to the atmospheric conditions when you zeroed your rifle, like barometric pressure, altitude, temperature and humidity. \u00a0If you zero at sea level and then go on a hunt at 10,000 feet, for example, the air will be thinner and exert less aerodynamic drag on the bullet which will change the trajectory and point of impact. \u00a0By including the atmospheric conditions in your model, Shooter will automatically compensate for different conditions.<\/p>\n

Drag Models are based on bullet shape. \u00a0Most manufacturers give G1 as their ballistic coefficient (BC) or G7 for boat tail bullets. \u00a0The BC of the bullet can also be auto-filled by the bullet library. \u00a0Minimum velocity refers to the BC of a particular bullet at different velocities. \u00a0As the bullet slows on long shots, the BC changes. \u00a0Shooter allows the input of these different BCs, however, if you only have one BC to enter, just use zero. And if you entered the bullet from the library, the minimum velocities are automatically entered for you.<\/p>\n<\/div>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n

\n\n\n\n
\"\"<\/a> <\/p>\n

Next in your ammo profile are the fields at which you zeroed the rifle.\u00a0 They include the range, the height above or below the point of aim where the round impacted, and the offset, or how far to the right or left of the point of aim that the bullet hit. For example, you may have zeroed at 100 yards with the round hitting 1\u201d low and \u00bd\u201d to the right of your point of aim.<\/p>\n

 <\/td>\n

\n\n
\n\"\"<\/a>\n

The left button, \u201cSettings,\u201d on your phone will bring up this sub-menu. Each of the options allows the phone to bring in data for you. Point your phone at the target to get the look angle and azimuth.\u00a0 The distance calculator is an easy converter for using your scope to estimate distance.<\/p>\n<\/div>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n

\n\n\n\n
\"\"<\/a> <\/p>\n

Spin drift takes into effect the centrifugal force of the spinning bullet, like a gyroscope effect.\u00a0 The Coriolis Effect is from the spinning of the earth and can affect long shots. The earth is spinning at roughly 1,000 miles per hour and even though you don’t feel it, the bullet does. These features can be disabled by putting the application in simple mode.<\/td>\n

\n\n
\n\"\"<\/a>\n

If you don’t want to rely on computer gadgets out in the field when taking 600 yard shots on wild boar with your Sharps .45-70 black powder rifle, you can always spit out a complete chart to your intended distance. This can then be emailed to your regular computer so you can print it out and take your own personal range card with you.<\/p>\n<\/div>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n

\n\n\n\n
\"\"<\/a><\/td>\n\n
\n

In the field or at the range, a course graph doesn’t help much, but one nice feature of Shooter is that you can compare two trajectories to each other on this graph screen. You click your settings button and it asks you what bullet to compare it to. You can even compare caliber to caliber and load to load. Nice feature. I just wish you could email the graph like you can the chart.<\/p>\n

 <\/p>\n<\/div>\n

 <\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n\n\n\n
\"\"Strelok (<\/strong>FREE)<\/strong> <\/p>\n

If you don’t want to spend the ten bucks, Strelok is really the way to go. Compared to the paid apps, with the exception of Shooter, it far outdoes them.\u00a0 The interface is simple and it pretty much does what you want it to do if you just want to get your shots on the paper. Until I test all of the variables like the Coriolis Effect and Spin Drift, I have to reserve judgment on their importance.<\/p>\n

The major downside to Strelok is that it doesn’t give you the ability to print a range card.\u00a0 You have to take your phone into the field or to the range, and you\u2019re dependent on that one distance that you plug in.\u00a0 I have to admit that I almost wrote off Strelok because I thought it was only available in metric. It does default to metric when you download it, but one of the three settings you can change is \u201cuse metric,\u201d which you uncheck.<\/p>\n

Not on the list here is a free app from the same guys who make Shooter. It\u2019s called Reticle Ranger and you can access it through the Android Marketplace. It is a range calculator based on using the MOA or MILS markings in your reticle, compared to target size.<\/p>\n

\n\n\n\n
\"editfirearm1\"<\/a> <\/p>\n

The distance is the one you are solving for.\u00a0 If you don’t know your distance, get a rangefinder or use Reticle Ranger to estimate it using your Mil-Dot or MOA reticle.\u00a0 Slope angle would be the \u201clook angle\u201d from Shooter, the angle your target is in relation to you.<\/td>\n

\n\n
\n\"\"<\/a>\n

The first button is all about your zeroing distance and scope you used. You can select your actual reticle on your scope from most brands. The middle button is the weather conditions in which you zeroed.<\/p>\n<\/div>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n

\n\n\n\n
\"editfirearm1\"<\/a> <\/p>\n

The bottom button is all of the specifics for the particular ammunition you are shooting. There is no bullet library like with Shooter, but you can get the BC of most bullets from the manufacturer\u2019s website.\u00a0 You input the muzzle velocity, which again should ideally be measured. \u00a0The temperature fields are somewhat like the MV Variation field in Shooter. \u00a0If you test your ammo at different temps, you can put how much it changed velocity per 15 degrees temp change.<\/td>\n

\n\n
\n<\/a>\"\"<\/a>\n

It will then give you specific distances in your reticle for this rifle\/ammo combo. It is almost like a range card for your reticle, but there is no way to export it to print it out.<\/p>\n<\/div>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n\n\n\n
\"\" Ballistics Calculator <\/strong>(FREE) <\/p>\n

This is an actual GPL (general public license) piece of software that is available for Android.\u00a0 It’s a little clunky and you can’t save any profiles, but it does what you want it to do for the most part.\u00a0 By now I expect you are spoiled with features. This really one has none, but it works.<\/p>\n

 <\/p>\n

\n\n\n\n
\"editfirearm1\"<\/a> <\/p>\n

The basic fields that you need to input are available in the GPL Ballistic Calculator, but some things don’t make sense. It asks you to put in weather parameters, but it doesn’t ask you what they were when you zeroed the rifle. Putting your zero at zero would probably address this.<\/td>\n

\n\n
\n\"\"<\/a>\n

There is a table tab with this like Shooter, but there is no way to export it, and it really doesn’t save your data when you close the program. So other than jailbreaking your phone so you can take screen captures, or shooting terrible pictures like these with a camera, you don\u2019t have any other options. For a free app, you\u2019re better off with Strelok.<\/p>\n<\/div>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n\n\n\n
\n\n\n\n
\"\"M-Star Ballistics Calculator – $2.99<\/strong> <\/p>\n

If there is one in the lot here that will involve 100% buyer remorse, it will be this one.\u00a0 It comes up 4th in the Android Marketplace list and it really should be taken out. Throughout the paid application are ads linking you to other things, presumably just as bad as this.<\/p>\n

 <\/td>\n

\n\n
\n\"\"<\/a>\n

These are the only fields available to you. Don’t waste your time on this terrible piece of paid software.<\/p>\n<\/div>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n\n\n\n
\"\"Hunter Joe Ballistics – $0.99<\/strong> <\/p>\n

At the price of a dollar, I’m not sure it is a huge jump to try this interesting but mostly useless app for Android.\u00a0 I don’t know why they would go to the lengths to make something so good looking with such little practical function. From what I can tell, it\u2019s geared for hunters with very little ballistic knowledge.<\/p>\n

 <\/p>\n

 <\/p>\n

\n\n\n\n
\"editfirearm1\"<\/a> <\/p>\n

The basics of a ballistic formula are the input fields once you choose a rudimentary rifle from a series of pictures. \u00a0Note that they misspell MOA as MAO. \u00a0Er….<\/td>\n

\n\n
\n\"\"<\/a>\n

There is a chart after you put your variables in, but it doesn’t give you the MOA, just the inches, and a confusing \u201cclicks\u201d field. \u00a0\u00a0I wouldn’t waste the dollar on this app.<\/p>\n<\/div>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n\n\n\n
\n\n\n\n
\"\"Reticle Ranger (<\/strong>FREE)<\/strong> <\/p>\n

Already mentioned above is the ultimate Mil-Dot\/MRAD or MOA tool for your Android, from the same developer as Shooter.\u00a0 Reticle Ranger allows you to input the size of your target, like a deer you estimate to be 4′ at the shoulder, and what the range marks inside your reticle measure, as in Mils\/Mrads, or MOA.\u00a0 Once you have a scope that uses these internal markings, it will be easy to understand their value. \u00a0Rangefinders are great, but long distance they need to be steadied and you may not have time to do a lot of fiddling around before losing the shot. \u00a0As a standalone app that is free, Reticle Ranger gives you an easy, quick input system to get your estimated distance fast.<\/p>\n

Simple calculations in Reticle Ranger save you a lot of math. \u00a0Combined with an MOA or MRAD\/Mil-Dot scope that has already been either calibrated for your caliber, or for which you are carrying a range cards, this app is really all you need.<\/td>\n
