About HandloaderPro

HandloaderPro is a precision reloading log built for handloaders — the people who sit down at a bench to make ammunition deliberately, one round at a time, and care what was different about last weekend's batch.

It exists because spreadsheets and spiral notebooks are not a good way to track years of load development data, and because the records you keep about your reloading should not be visible to anyone but you.

What it does

HandloaderPro tracks every reloading session you log, with the full recipe attached — bullet, powder charge, primer, brass, seating depth, chronograph numbers, group sizes, and any free-form notes you want kept with the load. It tracks your component inventory across bullets, powders, primers, and cartridges. It connects sessions to recipes so you can find any load you have ever built, in seconds, with the history attached.

It is multi-caliber from day one. It is account-based and private. It does not aggregate your data, does not sell it, and does not feed it to AI services or marketing platforms. It is a record-keeping tool for handloaders, full stop.

Who runs it

HandloaderPro is built and operated by Rob Bazinet of Still River Software Company, LLC — an independent software business based in Connecticut. There is no venture capital behind the product, no exit timeline, and no third party with a claim on what gets built or how the data is handled.

I’m a handloader. The application reflects that — it’s opinionated about the data model in ways that only make sense if you spend time at a reloading bench. If something feels wrong for the way you reload, tell me. Email goes to support@stillriversoftware.com and I read every message.

What's next

The pieces that matter most to handloaders go first. Better filtering and comparison across sessions. Easier ways to spot patterns in long-running recipes. Export so the data is portable. The product follows the data model handloaders actually use, not whatever happens to be easiest to build.
