How to drive the app
Eleven walkthroughs of the app itself, in the order a new user actually needs them. Each one is a screen-by-screen path with the values that matter and the mistakes that quietly ruin a solution.
If you have just installed the app, work through the first group in order — it takes about ten minutes and produces a rifle profile you will reuse for years. The rest can be read as you need them.
Set it up
Getting started
From fresh install to a usable firing solution. Units, language, one rifle, one load.
Read → 7 min readRifle profile
Field by field, with the measurement for each. The five numbers that make a solution describe your rifle.
Read → 6 min readChoosing a load
Find your ammunition, understand which of its numbers are yours and which are the manufacturer's, and enter handloads.
Read →Use it at the range
Firing solution
Every field on the solution screen, what it means, and which ones warn you that the answer is shaky.
Read → 5 min readDOPE card
Generate the table, export the card, label the conditions. Why paper still beats a screen at the firing line.
Read → 5 min readReticle holdover
The correction drawn on a reticle instead of read as a number. When holding beats dialling.
Read → 5 min readReticle ranging
Measure a known size in the reticle, get a distance, send it to the solver. The fallback that always works.
Read → 5 min readAngle, azimuth, map
Shot angle from the tilt sensors, azimuth from the compass, distance and bearing from the map.
Read →Get it right
Weather and conditions
Station pressure vs sea-level pressure, thermometers in the sun, and how precise each input needs to be.
Read → 6 min readTruing walkthrough
Collect the impacts, feed the screen, and judge whether the number it proposes is believable.
Read → 6 min readTraining log
Three session types and the numbers each one computes. What to record so the season adds up to something.
Read →Put it in your range bag
Ballistic Calculator is free, works offline and runs the same point-mass solver on every screen you have just read about.
