Takes the output of Applied Ballistics and converts it into a labels suitable for attaching to a scope turret.
This means you can calculate the ballistics for the environment, load and other variables on the day of a competition, print and attach to the scope.
The program output is a pdf file that can be printed on something like a DYMO LabelWriter 450.
This is a Ruby program so you need Ruby installed. Below is assuming MacOS and Homebrew is used.
brew install ruby
bundle install
bundle exec ruby turretbdc.rb -h
See example_input.csv for an example of what kind of data the program expects.
- Click Edit -> Units -> Input -> Metric
- Pick your bullet from the database. Use Applied Ballistics Custom Drag Curves if available.
- Enter Muzzle velocity, Zerorange, sight height and twist rate as appropriate
- Set "Avg. Wind Speed" to 0. Leave spin drift on.
- Set temperature, pressure and humidity as you have measure or expect it to be when shooting.
- Set heading to 0.
- You'll get one mark per entry in the range card, so set increment and max distance to whatever you'd like printed.
- File -> Export range card
This has only been tested with mils and the metric system.
