My target generator app has really evolved, with the ballistics app becoming a major part of it. I’ve pretty much completed the rifle/scope mounted digital dope card. It’s really more than a dope card, because it displays a graphic of a reticle and the recommended holdover and displays your chronograph data and tilt-cant etc. I’m just finishing up the mount design. I’ll post some photorealistic a video later. But, @Pumacarl challenged me to coming up with a hud and so I’m going to try, but only after I attempt my next project for the app. Which brings me to the title of the post.
My free app allows you to use the manufacturer’s BC if available. If not you can enter one in from either your own BCs or from the excellent HAM BC database. If you have an FX True Ballistics or FX Pocket Pro the app will connect to these and use their BC and add it to the database. My app keeps track of all of the BCs separately and also keeps a community average BC for each projectile. The shooter can choose which they prefer to use in the calculations. The value of a community average becomes higher if the pool of users using a BC capable chronograph is larger. The barrier to this of course is the cost of BC capable chronographs. $500 U.S. currently the average cost of entry.
I like a challenge and my next project is going to be a Doppler radar chronograph. It’ll probably take a little longer than the current project, but it’ll be fun. It’s not aimed at replacing a high dollar chronograph.
My requirements
1. Accuracy
2. Ease of use
3. Calculate and record Ballistic Coefficients (BC)
4. Link to the app and digital dope card via Bluetooth
5. Low cost in relative terms.
I’m very interested in hearing what features, others would like to see in a chronograph? Something maybe their current favorite doesn’t offer.
