Works well for me.

Been using this for years now and comparing it to another super calculator I use. For the practical application I use Bullet drop. I shoot competitions from 200-1000yds known distance. My chronograph speeds, speed at the target, and bullet drop are all pretty good. To site in shots……I’m in.

Excellent app

I have no notes on how to improve this app. Maybe could use metric as an option

Perfect for me

Straightforward to use but works fine producing same results as others I’ve tried.

It’s been updated!

Just letting everyone know the app creator updated this after a very long hiatus. You can now delete entries, including the ones that were already loaded in the download. This is the best app and easiest to use.
