IRON NEST Guides
Use practical IRON NEST guides for first firing solutions, spotter relays, triangulation, map measurement, zeroing, and missed-shot troubleshooting.
Choose the guide that matches your problem, then move straight into the calculator that completes the job. If you already know final gun-to-target range, go directly to the IRON NEST Ballistic Calculator for charge, elevation, and a firing card. These guides keep map reading, geometry, firing references, and impact correction separate so one bad input is easier to find.
Plan my first firing solution
First Firing Solution
Turn a bearing-and-range report into coordinates, a firing bearing, final range, and a checked firing card.
Follow the full workflow →Locate a target from spotter reports
Spotter Relay and Triangulation
Choose between chained vectors and intersecting constraints without moving the gun origin.
Choose the correct method →Check map measurement and zeroing
Map Measurement and Zeroing
Record coordinates, bearings, ranges, and angular units consistently before changing the load.
Run the input checklist →Diagnose why a shot missed
Why Your Shot Missed
Diagnose origin, bearing, unit, candidate, load, and correction errors in a stable order.
Troubleshoot a missed shot →From Question to Firing Card
A guide should end in an action, not another wall of text. Direct and relay reports continue to the Firing Solution Planner. Two independent constraints continue to the Triangulation Calculator. Once the final range is known, the Ballistic Calculator creates a community-reference firing card. Use the Mils Converter only when the report and sight use different angular units.
