The Reloading Log That Replaces Your Spreadsheet and Notebook
You worked up a half-MOA load two seasons ago. Can you still name the charge weight, the primer, and which rifle it was? HandloaderPro keeps every session, component, and result in one searchable place — rifle, pistol, and shotgun, smokeless or black powder.
No credit card required. $9.99/month or $99/year after your trial.
Coming from a Spreadsheet or a Notebook?
That's where this started — a spiral notebook, then a binder, then two spreadsheets that didn't agree with each other.
From a spiral notebook
A notebook can't be searched, can't be backed up, and can't tell you which of your last four 6.5 Creedmoor loads actually shot best. Log the same details you already write down by hand — they just stay findable.
From Excel or Google Sheets
A spreadsheet holds numbers but doesn't connect them. Nothing links a powder back to every load that used it, and the tab you added for a new cartridge never quite matches the others. Here, components and sessions are the same record.
From printed load sheets
Printed forms are fine at the bench and nearly useless a year later, once they're in a stack in a drawer. Same fields, same discipline — entered once, and permanent.
You don't have to retype ten years of loads
Start with the batch you're loading this weekend. Add an older load only when you actually want to look one up. Most handloaders have a genuinely useful history inside a month of normal bench time — with no migration project. And your reloading sessions export to CSV any time, so nothing is locked in.
Built by a Handloader, for Handloaders
HandloaderPro started at a reloading bench, not in a boardroom. It started with a spiral notebook, which became two notebooks, then a binder, then a spreadsheet — and then a second spreadsheet, because the first one wasn't built for the way I'd started organizing things.
Somewhere in there I realized the actual record of what I'd built — the place I went when I wanted to know which charge shot best — was spread across four places, none of them complete, and none of them searchable. So I built the thing I wanted: one private place for session history, components, and recipes.
Everything You Need at the Reloading Bench
From your component library to chronograph data, HandloaderPro keeps every detail of your handloading data organized and searchable.
Searchable Session History
Record every detail of your reloading sessions — charge weights, seating depths, chronograph velocities, group sizes, and bench notes — and find any load you've ever built in seconds, not by paging through a notebook.
Component Library
Catalog every bullet, shot, powder, primer, wad, hull, and cartridge you load with — manufacturer, weight, and full specs — so each component is a click away and linked to every session that used it.
Load Development
Build and refine load recipes over time. Compare sessions side by side to find the most accurate combinations — powder charge, seating depth, and primer for rifle and pistol, or shot, wad, primer, and powder charge for shotshell — smokeless or black powder.
Multi-Caliber & Multi-Gauge Workflow
Manage load data across every caliber and gauge you shoot — 6.5 Creedmoor, .308, 9mm, .45-70, 12 and 20 gauge, and beyond — without a separate spreadsheet tab for each one.
Load Data Provenance
Link every session to its published load data source — manual, online manufacturer data, or your own work — so you always know where a starting load came from and how it evolved.
Your Data Stays Yours
Account-based security keeps your load development data private. No marketplace, no shared feeds — your recipes are visible to you alone, and export is never locked behind a subscription.

Log Your Next Session
Start with the batch you're loading this weekend. The history builds itself from there — no backfilling required.
Built for the Way Handloaders Actually Work
Precision Rifle Shooters
Develop and document loads node by node. Track velocity standard deviation, group sizes, and seating-depth tests across barrels and seasons.
Pistol & Handgun Reloaders
Log plinking, defensive, and competition handgun loads with the same recipe detail — powder charge, primer, brass, and bullet — for every caliber you shoot.
Shotgun & Clay Shooters
Track shotshell reloads by gauge — shot, wad, hull, primer, and powder charge — so your trap, skeet, sporting clays, and field loads are all in one log.
Hunters & Field Shooters
Keep a permanent record of the hunting loads you trust — what worked, what didn't, and which components you'll pick up next.
Competitive Reloaders
Track match-grade ammo data with the rigor it deserves. Repeatable results start with repeatable records.
Black Powder Cartridge Shooters
Reloading black powder cartridges or shotshells? Log charges in grains or drams alongside your smokeless loads — cowboy action, BPCR, and classic calibers all belong here.
Common questions
How is HandloaderPro different from a spreadsheet or a notebook?
A spreadsheet holds numbers but doesn't connect them, and a notebook can't be searched at all. HandloaderPro links every session to the exact bullet, powder, primer, and case or hull it used, so you can search across years of load development and pull up any load you've ever built with its full history attached.
Can I import my existing spreadsheet or notebook?
Not automatically — entry is manual today. In practice that matters less than it sounds. Most handloaders start with the batch they're loading next and add older loads only when a question comes up, which builds a useful history inside a month of normal bench time. Your reloading sessions export to CSV any time, so nothing is locked in.
What is the best way to keep track of reloading data?
Record the same fields every time: cartridge, bullet, powder and charge weight, primer, case or hull, seating depth, the firearm, and the result. Consistency matters more than the tool you use. The point most handloaders outgrow a notebook or a spreadsheet is when they need to search across years, or see every load that used one particular component.
Does HandloaderPro handle rifle, pistol, and shotgun reloading?
Yes. HandloaderPro supports rifle, pistol, and shotgun (shotshell) reloading, with both smokeless and black powder loads. Rifle and pistol sessions track bullet, powder charge, primer, brass, and seating depth; shotgun sessions track shot, wad, hull, primer, and powder charge. It is one log for everything you reload.
Can I track multiple calibers and gauges in one place?
Yes. HandloaderPro is multi-caliber and multi-gauge from day one. Whether you reload 6.5 Creedmoor, .308 Winchester, .223 Remington, 9mm, .45-70, 12 gauge, 20 gauge, or all of the above, sessions and components stay organized per cartridge, gauge, and component.
Do I need a credit card to try it?
No. Every account starts with a free 14-day trial and no credit card. After the trial, HandloaderPro is $9.99 a month or $99 a year.
What happens to my data if I stop subscribing?
It stays yours. Data export is never behind the subscription — you can download your reloading sessions as CSV whether you're trialing, subscribed, or lapsed.
Does HandloaderPro sell my reloading data?
No. HandloaderPro does not aggregate, sell, or share your data, and does not feed it to AI services or marketing platforms. Your sessions, components, and recipes are visible to you alone.
Who builds HandloaderPro?
Rob Bazinet, an independent software developer and handloader based in Connecticut. No venture capital, no exit timeline -- just a focused tool built by someone who reloads.
