Knight's Armament BulletFlight is a military-grade ballistic computer that provides quick solutions in the field. BulletFlight does not output information in table format but rather dynamically gives you the solution you need now to make that shot. Current weather conditions including temperature, pressure, humidity, wind speed, and wind direction can be input, as well as angles to the target as measured by the built-in accelerometer. The app then provides highly detailed solutions out to 3000 meters. Your weapon profile includes your scope MOA/mRad per click, and hence when you provide a range to the target, the app will simply show how many clicks you need to change the scope by for that range and wind speed.

Includes over 1400 projectiles including carefully-measured G7 BC database for VLD bullets. BulletFlight's G7 data is courtesy of Bryan Litz and I recommend his book:

Up to five ballistic coefficients with corresponding velocity thresholds may be used for each profile to enhance accuracy, or use a single G1, G7, or G8 value.

Several built-in profiles for the Army's M110 and M110C semi-automatic precision rifle, the Army's new XM2010 sniper rifle, the 14.5 inch SR16 rifle, The 50 BMG M107, .308 M40A3, .308 M24, and the 6.5mm KAC PDW allow you to get started quickly. You may alter these profiles, or add new ones.

This app is currently in combat use by military snipers in Iraq and Afghanistan.

Built-in profiles for common military rifles, but easily add more custom profiles.
Accurate bullet database with most major brands.
3000 meters range (2000 using simple screen).
Fast and accurate ballistic computation using G1, G7, or G8 ballistic coefficients.
Easy to use interface yet powerful and full featured. All relevant data on screen all at once.
User interface designed to minimize chance of input errors.
"Simple Screen" with distance wheel, but also "Full" screen where any exact range may be used.
Output in inches, cm, MOA, Mils, and scope clicks.
Option for Metric units. In most cases imperial and metric are visible at the same time.
Direct input for scopes with either MOA or mRad metric input (such as Schmidt & Bender).
Calculates 360 degree wind drift using either degree of O'Clock format input.
Wind speed may be specified in either miles-per-hour or meters-per-second.
Advanced atmospheric model.
Uses GPS to locate nearest weather station and then automatically gets weather data and altitude for ballistic computation.
Sight-in weather may be logged and stored for automatic normalization to standard conditions. So you may sight in at any temperature or altitude and later be accurate at any other temperature or altitude.
Built-in accelerometer will detect angle for improved accuracy.
Computes actual BCs from collected data. Some users will do this for each log of ammo before a mission.
Built-in mil-dot range calculator.
Calculates bullet twist / stability with a highly-accurate formula.
Computes bullet spin drift.
Built-in help screen.

Awesome Ballistics calculator!!

I have been using the military version for 3 years or so now with various calibers, mostly .260 Rem and .338 Edge. It has been flawless for me with 1st shot hits at 1400yds (4'X4' target) with the .260 Rem. and 3 shots into a garbage can lid at 1680yds with the .338 Edge. An accurate rifle with good MV data with a TOP quality rangefinder AND quality weather/wind meter is essential to get the most out of this program. I have converted some of my buddies who were using Exbal like I was to Bulletflight Military edition which is way better, and much more user friendly on the Iphone than Exbal is on a PDA!! Plus you dont need a cosign indicator on your rifle, set the Iphone on it and push the "get" button and the angle is recorded. Buy it you will like it!


I'm surprised there aren't a lot more reviews on this calc. as its pretty prolific in competition and field use.

I've been using this app for a few years with no problems at all. As with anything, the quality of information you get OUT of this is 100% dependent on the quality of information you put IN. Your atmospherics don't have to be dead nuts on but your going to want an accurate station pressure and temp/humidity.

This will get me within a few tenths at 1000 and closer... I've not used it past 1K and can not speak on the accuracy of either the wind drift or Coriolis compensation.

5 stars easily...


App works better than advertised. I have been using it for a couple of years and you will not need another one. Get Bryan Litz book, you will learn a ton.

I would like to be able to use my angle cosine indicator... I don't have a angle degree indicator. These devices (aci/adi) are spendy and wish I had option to switch between the two on the app.

I am not sure that a user could use this app for two different rifle/scope combinations i.e. One mil/mil scope and one mil/moa scope on a different rifle.

It would be nice to have an option where the user could choose metric/standard for each input field.
