I spent a lot of time developing this program. Mostly I built it for myself, for things I wanted, but I figured I would share it.

What It Does
- Build, edit, save, and export detailed load recipes with cartridge, bullet, powder, primer, brass, charge, OAL, seating depth, load density, notes, group-size data, and pressure-reference ranges.
- Use Auto Load Designer to rank powder and charge combinations from known start/max records using case fill, modeled pressure margin, OBT charge-node fit, and velocity flat-spot behavior. Designed loads can be saved directly or moved into Load Lab for review.
- Run powder suggestions and accuracy nodes as separate pop-out tools, with one best node per powder and modeled OBT / flat-spot scoring across multiple powder choices.
- Estimate modeled velocity, muzzle energy, bullet RPM, sectional density, ballistic coefficient/form factor, pressure, usable case volume, load density, powder burn percentage, seating depth, jump to lands, primer effect, and risk warnings for planning and recordkeeping.
- Use Berger-style form-factor analysis to separate bullet drag efficiency from sectional density and BC, helping identify low-drag bullets beyond BC alone.
- Calculate Greenhill bullet-stability screening from bullet diameter, bullet length, velocity, and barrel twist, with stability warnings included in load estimates and Auto Load Designer ranking.
- Generate load ladders with user-selected increments, PSI/CUP display, pressure-curve charting, CSV export, below-minimum warnings, over-pressure warnings, and possible accuracy-node highlighting.
- Maintain a cleaned, manufacturer-organized component database for cartridges, bullets, powders, primers, cases, scopes, and load-data references through the built-in Modify Database tool.
- Track saved loads in their own pop-out window and manage component inventory separately as component inventory.
- Track firearm inventory in Your Firearms with manufacturer, pet name, caliber, barrel length, twist, firearm weight, action/platform, serial or asset number, scope/reticle, notes, assigned saved loads, assigned chronograph strings, and a direct path into Advanced Ballistics.
- Save chronograph strings; view shot count, average, ES, SD, and assign each string directly to a firearm from the Chronograph page.
- Run a full ballistic calculator with drop, wind drift, velocity, energy, time of flight, charts, and CSV export.
- Use Advanced Ballistics to calculate holdover, wind hold, elevation/windage clicks, target view, and more exact scope-reticle views for many major scope brands.
- Print one-page zeroing targets with selected load data, a blank handwritten date field, a larger notes box, and a compact data panel that stays clear of the target grid.
- Export top-bannered CSV reports for load data, ladders, Auto Load Designer results, powder recommendations, accuracy nodes, chronograph data, and ballistic tables.
