Nerd stuff

The physics behind the app. Every number in these articles comes from WristBallistics, the same solver that runs on your wrist, not from a rule of thumb or someone else's table. The zero-conditions pieces also come as full white papers for the people who want every table.

Do weather conditions matter when zeroing your rifle?

Same rifle, same ammo, twenty feet apart: we ran one .308 through the two harshest shooting environments on Earth. The zero survives the trip untouched; the 1,000-yard aim point moves twenty feet.

Full white paper: Do atmospheric conditions matter when you zero a rifle?

Do you need zero conditions in a ballistic calculator?

The feature we didn't build: most ballistic apps ask what the weather was when you zeroed. We ran that form through the engine, and its maximum possible payoff is a seventh of one scope click.

Full white paper: Should you record weather conditions when zeroing a rifle?

How does wind affect a bullet at long range?

Drift grows faster than distance, the clock-system fractions tested against the engine, and why the wind at your position sets most of the shot even when it lies about downrange.

Part 2: How to read wind for long range shooting

How to read wind for long range shooting

Grass, leaves, dust, and mirage as a speed ladder, calling direction with the clock, why the best shooters call wind at the trigger, and where a wind meter actually helps.

Part 1: How does wind affect a bullet at long range?

What's the best distance to zero a hunting rifle?

100 vs 200 vs 300, solved instead of argued: trajectory arcs, point-blank range honestly explained, and the hidden price of far zeros.

Do you aim high or low when shooting uphill or downhill?

Both directions hit high, here is how much by angle and distance, plus the double-correction trap between your rangefinder and your ballistic app.

Does ammo temperature affect velocity?

Cold powder is slow powder: fps per degree explained, what it costs at 600 yards, which powder lines claim temperature stability, and how to measure your own load.

What environmental conditions affect bullet drop?

Pressure, temperature, altitude, and humidity on one ranked scale, from realistic swings of each. Measure pressure, model temperature, ignore humidity.

How does Wrist Dope know the weather where you stand?

Barometer, GPS, live weather, and a manual override that always wins: where every number in your firing solution comes from, device by device.

How far is too far to shoot a deer?

Retained energy, impact velocity, and the terminal rating on your wrist: where a .308 stops carrying enough, and why the app refuses to print a kill probability.

Companion: What are the odds of hitting a target at long range?

What are the odds of hitting a target at long range?

Your group size, your ammo's velocity SD, and your wind call, turned into one honest percentage. With an animated vital zone that shows the scatter the math integrates.
