## Description

The mobile internal-ballistics lab: predict velocity & pressure, calibrate the engine to your chronograph, and find your accuracy node. 34,000+ published loads, offline.

Strelok Internal Ballistics is the mobile Quick Load: an interior-ballistics workbench for precision handloaders. It's the load-development companion to Strelok Pro — Pro solves the bullet in flight, this app 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 the engine 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 at the bench.

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 here and in Strelok Pro.
- Develop a load here, then send it to Strelok Pro with its measured muzzle velocity (Rifles > Import from Reload on the Pro side).
- Strelok Cloud keeps your logbook, rifles and developed loads in sync across devices.

BUILT FOR SAFETY
Predictions are a development aid, not published load data. The app 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. This app is not a maximum-charge authority — you are responsible for safe reloading practice.

FREE & PRO
Free: browse the full catalog, keep your logbook, and run the prediction engine. Pro adds chrono calibration and Load Lab analytics — monthly or yearly subscription (7-day free trial), or a one-time Lifetime purchase. Subscriptions auto-renew unless cancelled at least 24 hours before the period ends; manage or cancel anytime in your App Store account settings.
