Holdover Armory

Holdover Armory puts your rifles, loads, and ladder tests in one place — synced across your devices via iCloud.

Built for precision shooters and handloaders who track what matters: barrel round counts, go-to loads, charge weight ladders, and the accessories mounted on every rifle.

ARMORY Your rifles, organized. Each entry tracks caliber, barrel life, twist rate, round count, and a full accessory manifest across 18 categories — from optics and muzzle devices to bipods and chassis. Add a photo and the app extracts its color palette to tint the interface.

LOADS Every load you develop gets a parametric cartridge rendering with color-coded markers — so you can tell your 6.5 CM loads apart at a glance. Track brass, primer, powder, charge weight, bullet, COAL, and CBTO. Mark your go-to load and it stays front and center.

LADDER TESTS Build charge-weight ladders right in the app. Log velocity for each step, then review your results on a velocity-vs-charge chart with color-coded data points. Find your node, mark the winner, and promote it to a load.

BENCH DATA Reference SAAMI specs, cartridge dimensions, and caliber-specific barrel life data without leaving the app. The caliber gallery renders every cartridge to relative scale.

PRIVACY Your data stays yours. Holdover Armory syncs through your personal iCloud account — we never see it, store it, or share it. No analytics, no tracking, no ads. Read the full policy at holdover.ca/privacy.
