Drop is mostly solved physics — your calculator nails it. Wind is the one you have to read, in real time, with your own eyes. It's the difference between shooters who hit at distance and shooters who get lucky. Here's a method you can actually use.
Why wind is so hard
Elevation depends on things you can measure precisely: muzzle velocity, BC, air density, range. Wind depends on a moving, invisible fluid that changes speed and direction along the entire flight path. The wind at your muzzle is rarely the wind at the target, and the wind between them matters most where the bullet is still fast.
The goal isn't a perfect number. It's a disciplined estimate you can correct from.
Step 1: Call the value
Wind "value" is how much of the wind pushes the bullet sideways. A wind blowing straight across your line of fire is full value. A wind blowing straight at or away from you is no value for drift (it mostly affects velocity a little). Everything in between is partial.
The clock method is the quick field shorthand, with you at the center facing 12 o'clock downrange:
- 3 or 9 o'clock → full value (use the whole wind speed)
- 1, 5, 7, 11 o'clock → half value (roughly)
- 2, 4, 8, 10 o'clock → about three-quarter value
- 12 or 6 o'clock → no value for drift
Strelok Pro does this resolution exactly — you give it speed and direction, it computes the true crosswind component — but knowing the clock logic lets you sanity-check the output and adjust on the fly.
Step 2: Estimate the speed
A handheld anemometer at your position is a starting point, not the answer. Read the mirage and vegetation downrange, because that's where the bullet flies:
- 0–3 mph: smoke drifts, you feel almost nothing on your face.
- 3–5 mph: felt lightly on the face, leaves rustle.
- 5–8 mph: leaves and small twigs in constant motion.
- 8–12 mph: dust rises, loose paper moves, small branches sway.
- 12–15+ mph: small trees sway; you're working hard for the hit.
Mirage — the shimmer through your spotting scope — is the best tell at distance. It runs flat and fast in strong wind and "boils" straight up when the wind drops to nothing.
Weight the wind near the muzzle. The bullet is fastest and spends the most time-per-yard early in its flight, so a crosswind in the first third of the range moves the impact more than the same wind near the target.
Step 3: Turn it into a hold
Once you have value and speed, let the solver convert it into a wind hold in MOA or Mils for your exact load and range. Then commit to the hold — a confident wrong wind call you can read off the splash beats an indecisive one you can't.
Step 4: Read the miss, correct the next
Long-range shooting is a feedback loop. Watch the trace or the splash. If you held 1.2 mil and impacted half a target-width downwind, your wind was stronger than you called — adjust and send it again. Over a string you converge on the truth far faster than any first-shot estimate.
Keep notes. The wind patterns on your home range repeat, and a log of "what I called vs. what hit" is the fastest way to get good. Strelok Pro lets you save and copy your solutions so you can build that record.
