Illustrative account data
For handloaders
Manage recipes and workups, deduct the exact components used, follow brass cycles, and connect target and chronograph results to the batch that produced them. Track component cost per round and compare it with a factory-ammunition price you enter to estimate savings.
See recipe trackingNo handloading required
Add firearms, track factory-ammunition boxes and lots, log each trip, and let ArsenalHQ update remaining rounds, firearm round counts, and barrel-life progress. Keep target and accuracy results connected so you can compare performance across range trips.

From the range to your records
Built around what actually happens at the range.
One continuous record
ArsenalHQ is built around the full ammunition lifecycle, reducing duplicate entry while keeping every deduction and round count connected to what actually happened.
Quick-log one or several firearms with handloads or factory ammunition. ArsenalHQ deducts the rounds used and keeps optional targets, weather, notes, and velocity data with the trip.
Track factory-ammunition boxes and lots alongside handload batches. Saving a Range Day reduces the correct ammunition, while a loading session deducts selected components and adds finished rounds.
Every saved Range Day updates each firearm’s lifetime round count and progress toward the barrel-life estimate you set. Review accuracy and velocity results across trips for the firearm that produced them.
Keep recipes, component lots, loading history, brass cycles, target groups, and chronograph results connected. Compare workup rungs by charge weight, MOA, average velocity, SD, and ES. Import Garmin ShotView, LabRadar, or generic velocity CSV files, or enter shots manually.
Inside the app
These examples use the same layouts and labels as ArsenalHQ, with sample account data added to show how the screens work together. Use only the parts that fit how you shoot. Recipes and workups are optional.
Quick log is the default. Location, weather, target analysis, and velocity data are optional.

Why ArsenalHQ was built
ArsenalHQ started with a familiar problem: keeping up with ammunition inventory and round counts across multiple firearms and calibers had become a chore. After every range trip, ammunition totals, firearm round counts, and accuracy data all had to be entered into a spreadsheet by hand. It worked, but it was cumbersome. ArsenalHQ was built to provide a more intuitive place to track ammunition, firearms, and the performance history of each one over time.
Recipes, inventory, firearms, and range history are isolated per account.
Download your account data instead of being trapped in one tool.
Recipe sharing is opt-in; the rest of your vault remains private.
Record keeping only. Never presented as authoritative load guidance.
Add a firearm, track factory-ammunition boxes or a handload, and log your first Range Day. ArsenalHQ’s getting-started checklist guides the rest.
