Part of the geladen.ch ballistics suite. Successor to the standalone TARAN tool. 1. What this tool is for Every shooter has a number they quote for their rifle. It is almost always wrong, and it is almost always wrong in the same direction: too optimistic. The reason is not dishonesty, it is arithmetic. The traditional […]
The first post ever published on this site said, in its entirety: Migration is in progress. That was a while ago. The migration is over. Here is what came out of it. → https://bc.geladen.ch geladen.ch ballistics — a client-side suite for small-arms external ballistics. Trajectory, hit probability, drag curves, your rifles and your bullets, a […]
A report on replacing a closed-form empirical spin drift formula with a physics-based model, and what happened when the result was checked against an independent, modern measurement source. Disclaimers Disclaimer 1 I am no ballistician. I am no mathematician. I am no physicist. I got my diploma 30 years ago, and my brain has not […]
The v = v + 0.1 of the “BC from Labradar tracks” calculator is here: https://bc.geladen.ch/labrabaco/labrabaco.html The major change is noise filtering. Most people who have plotted Labradar tracks in spreadsheet software, must have seen occasional tracks of this shape: The tail of the graph — beyond 60 ms — is obvious noise; there is […]

Some gunsmiths do not hesitate to charge obscene sums of money for a procedure that essentially lasts 15 minutes, and they multiply and spread legends with the motto “it’s very, very complicated”.

Full disclosure: To be clear, I am selling the Vortex and Vectors mentioned in the article. I chose them specifically for their qualities, and this test was to validate the choice before recommending them to others. It all started when I tested the “made in China” Vector Continental 34mm 3-18×50 FFP, and I was very […]
Labrabaco is a tool to calculate G7 BC values from Labradar tracks. Rejoice, citizens! The first official beta is out.
Nota Bene: this post contains excerpts from the Labradar user manual and quick start guide available at the official site here: https://mylabradar.com/download/. These, contrary to most of the rest of this site, are certainly not under WTFPL; I hope Labradar would not mind me repeating their instructions. 1. Read the Labradar manual, at least the […]
