Load Data Suite vs Strelok Internal Ballistics

Load development with the ability to compute shot group accuracy using our built-in shot group calculator. Load Data is an all-in-one inclusive reloading experience, from the reloading bench all the way to the range! At the reloading bench, use loads to develop a new load or fine tune an existing load. Create multiple load variations to accommodate for slight powder charge or seat depth variations. At the range, use range reports to get shot group spread, size and aim-to-zero measurements. Record the environmental conditions to understand how consistent the load is at various climates. -Develop and store load and load variations. -Store firearm information for ballistics and range reports. -Record range reports with multiple shot groups. -Get precise extreme spread (moa/in), group size (in), aim-to-zero (moa) from shot groups. -Stores shot groups in a list to compare load variations. -Change shot group reticle colors to ease in adding shots to target. -Store environmental conditions for each shot group. -Reloading components from most major reloading component manufacturers (over 2000 preloaded components). -Easily search for components to save time. -Multiple areas to add notes at any phase of load development. Typical Usage -Develop load/variations in the loads tab. -Add firearm used for reference in range reports. -Shoot targets. (optional) -Collect targets, open range reports tab and start adding shot groups. -View shot groups and compare results to determine best load variation for firearm/conditions.

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.
