Includes 2 rifles and 3 pellets per rifle, unlimited tunes. Pro Upgrade allows group measuring from target photos, unlimited rifles and pellets, and spreadsheet export. PelletVault is a serious tuning log for FX and other regulated PCP air rifle owners — built to replace the notebook, not just digitize it. Track every rifle you own, with as many pellets as you test: - Regulator pressures, macro and micro wheel, valve setting and opening (mm), Power settings, Hammer Spring and Dwell settings depending on brand of rifle chosen - Zero range in yards and metres, group size in inches and mm, shots per group with ability to upload target photos and measure groups. (Pro Version) - Photograph your target, tap each hole, and get your group size, mean radius, MOA and MIL, saved against the exact tune that shot it. - Weather conditions at the time of testing Save multiple tunes per pellet without losing your work — before experimenting, tap "Save as new tune" to branch off a fresh copy while your proven setting stays untouched. Full chronograph shot strings, not just one number: log every fps reading and PelletVault calculates average velocity, extreme spread (ES), standard deviation (SD), and muzzle energy automatically. Compare any combination of tunes side-by-side — settings, stats, and charts — and get a data-driven recommendation for which tune actually performs best, based on consistency and group size. Export the full comparison, charts included, as a real Excel file. Bulk edit in Excel or Numbers: export your whole vault as a spreadsheet, edit it, import it back. All data stays on your device — no account, no ads, no tracking, fully offline. PelletVault is a personal record-keeping application for documenting airgun and pellet tuning results. It does not connect to, control, or modify any firearm or airgun. It does not provide instructions for constructing weapons or ammunition. Built by Inscope Contract Shooting
