Title: ballistics programs
Post by: sailormike on February 13, 2017, 03:23:31 PM
So I recently got one of those Caldwell chronys and downloaded the app that goes with it. after a little trial and error, I finally got the app to function perfectly with my phone and really like it. I can even send it to my email in a spreadsheet. But it doesn't put it in a graph form,
 so my question is, what software/ app does everyone else like to use? I see a lot of interesting graphs etc that folks are attaching to their post and I would like to import my numbers to something similar. Links would be grateful
Here is an example of a string I sent to my email yesterday

I've seen people here mention Chairgun from Hawke Optics.

I would make sure you're using the usb connection or Bluetooth to the chrony, I got terrible results with the headphone serial cable, and I could listen to my books.

I would take the averages that come out of the shot strings and plug them into ChairGun, on the phone or computer.

If you are into statistics, break out excel and calculate bell curves that will let you know what percentage of your shots are going to be  in what speed range. Then plug those numbers back into ChairGun so you can see the spread of possibilities...

Thanks Ill give Chairgun a try. That's one that Ive heard of but couldn't remember the name. I'm better with my hands than I am with using a computer (shortage of living brain cells) so the more simple the better.
As far as the Caldwell chrony goes, I had a lousy time at first, could not get it to connect like so many others have complained about. decided to try it again and connected using the headphone jack. still not exactly sure what I did different but it had something to with order in which I connected the cable and turn the chrony on or open the app first, or vise versa. I just kept trying it in a different order and eventually got it right and it has worked perfect since

I usually email to myself then open in Excel and graph it there. Simplest way for me to do it anyways. I can highlight one or all the rows and graph the information I'm interested in seeing graphed. Good luck and happy shooting.

If you want simple, download the one I wrote.  Doesn't get any simpler.  It's free.  You can download it from my web server at:

Here's a screenshot.

See this thread (http://www.gatewaytoairguns.org/GTA/index.php?topic=121479.msg1177961#msg1177961) as well for a Google Sheets shot string analyzer by member Cathartes. Charts, graphs, and spreadsheets are nice and all to map out your shot string curve, tune your gun, and get #'s to punch into a program like Chairgun or Strelok. Once you get the info in there, it's always best to validate the data at the range.

Thanks for all the resources y'all. guess its time to learn a little about spreadsheets. remember, I fried a few too many brain cells in my younger days , in fact the first cell phone I ever saw was a household rotary dial phone mounted on the floorboard of a truck. I will figure it out though! I'm stubborn like that

Thanks techie that is just the ticket.

I can make that work for everything from my new Hatsan 135 vortex to my Handi rifle in .444 marlin.  :)

Nice work.
