Strelok Internal Ballistics vs DOPE Long Range Shooting Log

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.

DOPE (Data On Previous Engagements) is a professional, 100% private, offline-first shooting logbook built by a shooter for shooters. Designed to replace paper range notebooks, DOPE lets you record scope adjustments, atmospheric conditions, target positions, and plot shot groupings directly on virtual targets. KEY FEATURES: • 100% PRIVATE & OFFLINE-FIRST All your data – firearms inventory, ammunition records, range locations, and target photos – is saved strictly inside a local database on your device (SQLite). No account registration, no telemetry, no tracking servers, and zero ads. You maintain total control over your data with built-in JSON/ZIP backup export and import. • RANGE CONDITIONS & GPS LOGGING - Automatic or manual range location logging with GPS coordinates, map integration, and altitude (m a.s.l.). - Complete weather tracking: temperature, humidity, absolute station pressure, and wind speed/direction. - Built-in absolute pressure calculator and integration with Open-Meteo API for quick weather data fetching. • FIREARMS & AMMUNITION INVENTORY Keep a clear chronicler's record of your rifles and loadouts. The app automatically suggests your previously used rifles, calibers, and ammo for new entries to save time at the range. • SCOPE SETTINGS & CORRECTIONS Log your optic settings and turrets in MRAD, MOA, or clicks. Compare suggested ballistic corrections (e.g. from Lapua Ballistics) with actual scope adjustments used during firing. • VIRTUAL TARGET PLOTTING & GROUP CALCULATION - Plot bullet hits directly on your phone screen with simple touch controls. - Integrated magnifier tool to precisely align hit points against a millimeter grid. - Automatic group size and dispersion calculations in mm, MRAD, and MOA. - Support for multiple targets per entry and adding real target photos. • CLOUD SYNC AND BACKUP - Sync data between all your devices. - Store a secure back-up in cloud. - App can work offline and sync data later.
