Here is the email I was sent, with the links:
"Thank you for inquiring about our ballistic calculators. At the end of 2018 we ended support for our Chairgun and X-Act software. These desktop and smartphone apps will no longer be updated or supported by Hawke. They may continue to work for some time, but as operating systems are updated we cannot guarantee this.
Why did we do this?
We pioneered ballistics software over ten years ago and were the first optics brand to develop our own ballistics apps, which we made available free of charge. The original Chairgun software (which we acquired) predated even this. Since then, there have been huge developments in two key areas:
- First, our reticles have become self-explanatory and easier to use with natural aim points.
- Second, the software platforms have become ever more complex and difficult to support.
We've taken a strategic decision to leave ballistic software to the large community of developers out there so we can concentrate on what we do best: making great optics.
What can you do now?
There are a large and growing number of apps on the market which we think do a great job in helping the shooter with aiming and ballistics. We recommend you check them out. Our favorite at the moment is Strelok Pro, but there are also others available.
If you wish to still use our reticle programs, You may download legacy versions from these links:
