Strelok Internal Ballistics
This app helps handloaders predict firearm load performance, analyze powder temperature sensitivity, and track rifle components. It offers a comprehensive database of published loads and allows users to calibrate predictions to their specific rifle and chronographed velocities. The tool operates offline and integrates with other apps in its ecosystem.
- Predict muzzle velocity and chamber pressure
- Calibrate predictions to your rifle
- Automatic velocity node and charge finding
- Track powder temperature sensitivity
- Offline database of 34,000+ loads
- Logbook with component and chronograph data

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.

Verdict
The clearest difference is rating: Eagle Ballistics at 4.8 against Strelok Internal Ballistics's 4.0. Eagle Ballistics also leads on review sentiment (75% vs 40%) and ratings volume (30 vs 2). Strelok Internal Ballistics's advantage is update cadence (every 2 weeks vs monthly). On price, ads, in-app purchases and monetization model there is nothing between them.
