I wanted to share an update on several significant upgrades and new features now live on Ballistics.Systems.
Over the past few weeks, the platform has undergone substantial refinement with a focus on accuracy, usability, and long-term extensibility. These updates reflect ongoing work to make Ballistics.Systems a reliable, technically sound resource for shooters, reloaders, and precision rifle enthusiasts.
Highlights include:
Twist Rate & Stability Calculator Enhancements
The Twist Rate calculator has been improved with expanded bullet data, clearer stability modeling, and better handling of real-world bullet geometry. While the classic Miller model remains the foundation, the calculator now more clearly communicates assumptions and limitations so results can be interpreted appropriately.

New Satterlee-Style Ladder Test Tool
A new public Ladder Test tool is now available, designed to help identify stable velocity nodes using a structured, step-based workflow. It includes guided charge selection, velocity entry, automatic node detection, and a results summary with optional technical detail for those who want to see how the calculations are performed.
Pressure Check
The new Pressure Check tool helps reloaders evaluate whether a load appears to be operating within reasonable pressure expectations based on published data and known ballistic relationships. Rather than attempting to calculate absolute chamber pressure, it functions as a practical screening tool that highlights combinations which may warrant closer scrutiny during load development. When used alongside chronograph data and reputable load manuals, Pressure Check adds an additional layer of awareness to support careful, methodical, and safety-conscious reloading practices.
Improved Bullet & Cartridge Data
Bullet records have been expanded and normalized to support more accurate calculations across tools. Length, weight, caliber, and construction data are now handled more consistently, improving results across the site.
Purchase Link Integration (Non-Intrusive)
Where relevant, the site now provides optional purchase links that point to vendor search results rather than fragile product pages. This keeps links resilient while remaining clearly separated from the calculators themselves.
General Performance and UI Improvements
Behind the scenes, substantial refactoring has improved performance, reliability, and maintainability. On the front end, layouts and messaging have been tightened to make the tools clearer and easier to use without sacrificing technical depth.

This project is still evolving, and more tools and refinements are planned. If you have feedback, suggestions, or spot anything that could be improved, I welcome hearing from you.
Thank you for your continued interest and support.
