The GunSim Application is not currently found on BlackBerry App world, but the GunSim Company has created a Ballistics App specifically for BlackBerry smartphones. You can set the left “Convenience key” on your BlackBerry to automatically load the ballistics program when you need it. To do this, simply visit Options from within your BlackBerry menu, then scroll through the Options menu to Screen/Keyboard. Select it and scroll down to the
Convenience Keys listing. You have left and right, scroll to the left and select the option that it currently opens, you will then see a list of items that can be assigned to that key; select the GunSim application and save.

Before you even take out your rifle to start shooting, you should go ahead and input the details into the Ballistic calculator, details which will more than likely remain constant; info such as Bullet Diameter, Muzzle velocity etc.
In the actual Gunsim calculator, not the Ballistics, you will enter other needed information including, the Range or Yard, Uphill Angle if any, Wind Speed in MPH and so on. These details will often change while you are shooting. The good thing is that you do not need to press a calculate button whenever you update the information, it will auto calculate as you type in the info, so you can really do this with just one hand if you need to.
There are 9 different numbers or calculations to pay attention to, these include; the elevation, distance, velocity, windage, etc. Wind calculations, elevation and lead can be viewed in both scope clicks and inches or you can choose to view MOA and Millimetres which you can set from the options menu of the app.

The Known Distance on the screen will tell you how many millimeters or MOA that a target distance is, based on your specified number. For instance, if the target distance was 24 across, that would be approximately 4MOA, you will come up about 2 MOA or 8 clicks depending on your settings and that makes this feature great for come-ups and range-finding.
