Predict the load before you pull the trigger.
Strelok QuickLoad is an interior-ballistics workbench: a real on-device engine predicts muzzle velocity, peak chamber pressure and case fill from your components, calibrates to your chronograph, and surfaces your accuracy node — the internal-ballistics companion to Strelok Pro, on iOS and Android.
An engine, not a lookup table
Pick a cartridge, powder and bullet and QuickLoad predicts muzzle velocity, peak chamber pressure and case fill across the whole charge range — fit to 34,000+ published loads and plotted against the SAAMI/CIP maximum, fully offline.
Calibrated 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 analytics
Velocity-node (OCW) detection, lowest-spread charge, powder temperature sensitivity and barrel-life tracking that sharpen as your logbook grows.
