Holdover Armory is a purpose-built tool for precision rifle hand-loaders. Organize your rifles, develop loads, run ladder tests, and track prep sessions — all in one place.
Key features:
• Rifle profiles — Store barrel length, twist rate, caliber, and zero distance for every rifle in your collection.
• Load development — Log powder charges, bullet weights, brass, primers, COAL, and velocity data. Keep detailed notes on each load recipe.
• Ladder tests — Record shot groups with ES, SD, and velocity data at each charge weight. Compare results to find your node.
• Prep sessions — Track brass prep, primer pocket work, and other reloading activities with timestamps and notes.
• Accessories — Catalog dies, presses, scales, and other equipment.
• Custom calibers — Add wildcat or uncommon chamberings not in the default list.
• Offline-first — All data stays on your device. No account required, no data collection.
• Dark interface — Designed for low-light conditions at the reloading bench.
