Qual8 by Sigma8 Labs
Your best tune → Faster.
Accuracy. Mathematically Optimized.
Qual8 is a rifle analytics app for tuning handloads and comparing factory ammunition. Log velocity, plot groups, and build a rifle record that turns range data into clear next steps.
What Are You Looking For?
Three questions. One app.
Which factory ammo shoots best in my rifle?
Start with free Range Sessions across every rifle. Marksman also unlocks one active rifle for factory-ammo work: Complete factory-ammo comparison on one active rifle. Switch the active rifle quarterly. Hunt Qualified records on the active rifle.
Marksman
How do I keep track of what I'm loading and what's working?
Unlimited rifle profiles, group statistics, target photo storage, and structured data logging. Replaces the notebook and the spreadsheet. Your data is permanent — it never disappears, even if you downgrade.
Free
Where's my best load hiding in this data?
Premium Handloader adds patent-pending handload optimization on one active rifle. Elite Handloader unlocks the Reloading Workflow across every rifle, every load, and every optimization path.

How Qual8 Works
From range data to tuning direction.
You go to the range and fire groups. For each group, you enter velocity data from your chronograph and either photograph your target on a Sigma8 Calibrated Target or plot your shots on a digital grid.
Qual8 calculates velocity statistics, group precision using mean radius, and tracks point of impact across loads. Then it maps your accuracy landscape across charge weight and seating depth to identify the combination that produces the tightest groups with the most consistent velocity.
It tells you how wide your sweet spot is — because a load that only works within a .003" seating depth window will fall apart when your throat erodes. A load that works across a .030" window is one you can trust for years.
The app does not generate load data. It does not replace your reloading manual. It takes the data you collect at the range and turns it into analysis that would be difficult to build by hand.
Calibrated Targets
Calibrated targets are part of the data.
Qual8 can plot shots digitally, but the target-photo workflow depends on calibrated target geometry, clean bullet holes, and accurate scale. Printed Sigma8 targets handle the paper and print settings up front. Free PDFs are available for shooters who print their own.
Print Standard
Sigma8 recommends 60 lb matte white paper. Minimum paper weight is 40 lb. Standard printer paper is too thin for reliable bullet-hole detection, and glossy paper should not be used.

The Ecosystem
Every Sigma8 product connects to the app.
The physical tools collect the data. The app interprets it. The framework teaches why both matter.
| Sigma8 Product | App Connection | Ecosystem Role |

Your data exists independent of any device, account, or subscription. The Sigma8 Precision Logbook is your permanent physical record. We are not trying to lock your data inside a subscription — we are trying to make it more useful.
Choose Your Tier
Start free. Unlock depth when you need it.
Qual8 starts with free Range Sessions, then expands into two paid lanes: factory-ammo comparison across every rifle, and patent-pending handload optimization for reloaders.
Range Sessions stay free across every rifle, while deeper factory-ammo and handload workflows unlock by tier.
