Chairgun on your I Phone

I use it on my droid. Works great and have referenced it a few times in the field when I couldn't remember windage or elevation at a certain distance.

I use chairgun on my iPhone 6, its great, especially once you start shooting long range in windy conditions.

Matt Dubba has a few videos about using phone apps for shooting.

I use it on my Samsung S5. It's excellent for adjusting your scope for different distances (gives you the clicks required from your zero). Chairgun in combination with a chronograph allows you to adjust your scope bang on.

Where do people get the ballistic coefficient value for different pellets?
Also, how to calculate for non Hawke reticules? 
Apologies if these are dumb questions, but I'd like to learn accurate holdover.

The BC is found on Hawke Chargun Pro's pellet database. There is a little tab on the right titled 'Pellets' that you can click on and see 100's of different pellets from .177 to big bore. 


There are also many different types of reticles on Chairgun's database that you can choose from.
I use this app on my IPod Touch and it really does help calculating holdover and the number of clicks at different ranges. 

Randy Thanks very much; I look forwards to playing with this app.
