Strelok Reload Ballistics
Internal Ballistic Calculator

Shooters World powders join the catalog, and your developed loads now flow straight into Strelok Pro.
Strelok Reload is an interior-ballistics workbench for precision handloaders. It's the load-development companion to Strelok Pro: Pro solves the bullet in flight, QuickLoad helps you build the cartridge — and predicts what that cartridge will actually do before you ever pull the trigger.
PREDICT YOUR LOAD — ON DEVICE
- Pick a cartridge, powder and bullet, and QuickLoad predicts muzzle velocity, peak chamber pressure and case fill across the whole charge range.
- A live chart plots velocity and pressure against the SAAMI/CIP maximum, with a clear over-pressure warning zone.
- The engine is fit to 34,000+ published loads and runs entirely on your device — no signal needed.
CALIBRATE IT TO YOUR RIFLE
- Enter the velocities you actually chronographed and the engine tunes itself to your barrel and powder lot, so every prediction is personalized — not a generic table.
LOAD LAB — YOUR DATA, SMARTER
- Find your velocity node (the flat spot / OCW window) and your lowest-spread charge automatically.
- Track powder temperature sensitivity (fps/degF) and barrel round-count and life.
- The more you log, the sharper your load development gets.
A REFERENCE THAT WORKS OFFLINE
- 34,000+ published loads across 519 cartridges and 100+ powders, normalized from Hodgdon, Vihtavuori, Alliant and Norma data.
- Browse by cartridge, then filter by bullet weight and powder — start/max charge, velocity, pressure and COAL, with SAAMI/CIP context. The whole catalog lives on your device.
A SMARTER LOGBOOK
- Record loads with full component detail and chronograph strings.
- Automatic statistics: average velocity, standard deviation (SD) and extreme spread (ES).
- Track rifle profiles and your powder, primer, brass and bullet inventory.
PART OF THE STRELOK ECOSYSTEM
- One Strelok account works in both QuickLoad and Strelok Pro.
- Develop a load here, then send it straight to Strelok Pro with its measured muzzle velocity.
- Optional cloud sync keeps your logbook and rifles on every device.
BUILT FOR SAFETY
Predictions are a development aid, not published load data. QuickLoad always shows the start charge, clamps and warns against SAAMI/CIP maximum, and reminds you to start low and work up while watching for pressure signs. Always cross-check against your component manufacturer's current data. QuickLoad is not a maximum-charge authority — you are responsible for safe reloading practice.
FREE & PRO
QuickLoad is free to use: browse the full catalog, keep your logbook, and run the prediction engine. Strelok QuickLoad Pro adds chrono calibration, Load Lab analytics, and cloud sync. Monthly and yearly subscriptions (7-day free trial), or a one-time Lifetime purchase, which does not include a free trial. Subscriptions auto-renew unless cancelled at least 24 hours before the period ends; manage or cancel anytime in your App Store account settings.
