New Ballistics Calculators

[dcali]

Hello All -

I've just finished a major rewrite and expansion of the online ballistics calculator section at https://bisonballistics.com. There are now six different calculators (they're all free).

1) the regular point mass trajectory calculator: this has been updated to provide better charts and to allow the use of BCs in addition to selecting a bullet from the library. Altitude can now be substituted for pressure.

2) a recoil energy calculator: this uses the SAAMI method to estimate recoil energy.

3) a stability calculator (Miller based): Pretty much like other stability calculators, but with charts.

4) a bullet comparison tool: basically, an interface to run to trajectories side by side, updated with a better interface and charts.

5) a statistical hit probability simulator: monte carlo simulation of trajectories with random parameters - similar in concept to the AB WEZ. You can use it to see the impact of the variance of things like BC, velocity, and wind direction.

6) a simple velocity estimator: dead simple velocity estimator based on the velocity of a known bullet.

If you guys could take it for a spin and let me know if there are any bugs, or just general feedback, I'd appreciate it. It's always a work in process. Thanks!

Very cool! Thanks for the links.

Just playing with the comparison tool I found an issue. The lines on the charts aren't labeled for say "bullet A" and "bullet B". It has "windage" on both.

Very cool though. I'm sure I will use this one a lot.



Just noticed the color index below my screenshot.

Thanks. That is a bug! Exactly why I posted here. The legend should show the bullet names. I'll get that on the list to fix.

Edit: should be fixed now. Thanks for the heads up.
