Overview
isochronX is the first ever app that computes bullet ballistic coefficient from shooting range data. Just input muzzle velocity, environmental data, and bullet drop at different ranges, and isochronX will compute the G1, G2, G5, G6, G7, and G8 ballistics coefficients for your projectile. It will also indicate the order in which the different G-models are best suited to your projectile.
Notes for use:
All available pages must be visited before the BC can be computed etc.
Accurate environmental data is a must for accurate results.
At least one point should be entered beyond the muzzle that is around 100 yards or less from the muzzle for accurate initialization.
Enter at least two data points past the muzzle. Range has default increments of 100 yards, but any increments can be used. Note that not all available trajectory data fields need to be entered. Please provide any feedback or questions to [email protected].
You can enter negative numbers from a phone by holding down the '.' key until the negative sign key comes up.
Drop data is positive up, so a "drop" that is above zero must be entered as a positive number. For example, a 110 grain VMax with 2.4" sight height and 200 yard zero might have the following data:
Distance (yards), Drop (inches)
0,-2.4
100, 2.5
200, 0.0
300, -10.40
400, -30.60
500, -62.80

Precision computation of bullet ballistic coefficient from range data
What's new
This app is in Beta release. It is fully functional but is still a work in progress. We plan to add many features that are currently missing from this very Spartan app. Early adopters will get free upgrades for life regardless of the eventual sales price.
1. Pages save data that was entered in this session so you can return to previous pages and make minor modifications. The default data will still show up when you close and re-start the app.
2. Zero range other than 100 yards now works.
3. Trajectory that goes above 0 before returning below is now handled properly.
4. Help available for some pages that might not be otherwise easy to use.
5. System will warn user if range and trajectory data are not consistent or as expected.
6. Shows drop, velocity, and time of flight for all six ballistic coefficients on final screen.
