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. These guides keep map reading, geometry, firing references, and impact correction separate so one bad input is easier to find.
START HERE
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 →TWO REPORTS
Spotter Relay and Triangulation
Choose between chained vectors and intersecting constraints without moving the gun origin.
Choose the correct method →CLEAN INPUTS
Map Measurement and Zeroing
Record coordinates, bearings, ranges, and angular units consistently before changing the load.
Run the input checklist →TROUBLESHOOT
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.
