Load Intel vs Strelok Internal Ballistics

Load Intel is a reloading log designed for shooters who want their data organized, consistent, and always accessible—without accounts, cloud sync, or subscriptions tied to an identity. The app provides a structured way to record and manage load data over time, keeping experimental loads separate from proven ones so results stay clear and repeatable. Everything is stored locally on your device, making it reliable at the bench, at the range, or anywhere without service. Track essential load details including caliber, bullet, powder, charge weight, primer, brass, COAL, trim length, and notes. Log chrono results such as velocity, ES, and SD, along with group size and performance observations. Attach photos or videos to individual loads to document targets, brass condition, or test setups. Load Intel is built around long-term data integrity. Tested loads remain distinct from new experiments, edits are intentional, and backups are fully user-controlled through export and restore. There are no accounts to manage and no data stored on external servers—your load history stays with you as long as you keep a backup. Load Intel is intended as a practical, no-nonsense tool for reloaders who want their load data organized and dependable for years to come.

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.
