CONTROL THE
PROCESS.
TRUST THE SHOT.

OFFICIAL LAUNCH COMING SUMMER 2026

Tools to measure what matters, the software to understand what the data means, and the education to act on it with confidence — from the bench to the field.

Qual8 App
For any shooter who wants to know exactly how their ammo performs.
The first app to put a systematic feedback loop behind what you're already doing — qualifying your ammunition and your performance from bench to field. Factory or handload. Free to start.
Try Proto-Qual
The 8-Bench System
For the reloader — whether you're just starting out or want data behind what's already working.
A proven, sequential framework for your reloading bench. Every variable measured. Every step validated. Start at Bench 1 and build the process from the ground up — or plug in at any bench to add structure to what you're already doing.

First of Its Kind

Most apps track shots. Qual8 qualifies them.

Bench to Field Qualification
Earn your Accuracy Qualified (AQ) and Velocity Qualified (VQ) badges at the bench - proving your ammunition performs consistently. Stack them into Load Qualified (LQ) when both check out. Then prove yourself in the field with Field Qualified (FQ) - real positions, real distances, real conditions. Do not calculate your distance. Prove it.
49+ Variables. Zero Guesswork.
Environmental conditions, equipment control points, session constraints - the app captures all of it. If conditions compromise your data, Qual8 flags it before you draw the wrong conclusion. Engineering judgment, not just a tracker.
See Where You Stand
Compare your rifle and load performance against every Qual8 shooter in the population. Whether you are shooting factory ammo or handloads, you are in the same system - ranked by results, not experience level.
You do not have to reload to know which ammo your rifle actually prefers. Qual8 works for factory ammo shooters from day one - free.

Qual8 Calibrated Targets

Print the target that matches the work.

These free PDF targets are built for Qual8's target-photo workflow. Use them now for range work, ammo comparison, load development, and qualifier practice. When Qual8 launches, the app will use the target identity and geometry to turn photos into measured results.

2x Calibrated Target

Factory Ammo

The primary factory-ammo comparison target. Shoot two groups from the same box of ammo and give Qual8 clean comparison data.

Download 2x PDF

3x Calibrated Target

Range Session

The primary range-session target. Shoot three groups to sight in, build confidence, compare ammo, or prepare for a qualifier.

Download 3x PDF

4x Calibrated Target

Load Development

The workhorse target for handload development. Four groups on one sheet make it the default for structured powder, seating, and comparison work.

500 / 1000 Yard MOA Target

MOA Reference

A clean single-target sheet for any session where one aim point is preferred. Rings are calibrated to exact MOA scales at 500 and 1000 yards.

300 / 600 Yard MOA Target

MQ Qualifier

A single-target sheet calibrated to exact MOA scales at 300 and 600 yards. This is also the MQ qualifier target family for Qual8.

HQ Hunt Qualifier Target

HQ Qualifier

Qualify your setup from real field positions: prone, sitting, kneeling, or standing. Run it from 200 to 500 yards in 50-yard steps and prove the vital-zone result.

Reloading is not a checklist.It is a workflow.

Most reloaders struggle not because they lack tools - but because nobody has shown them how the steps connect. The 8-Bench Framework turns reloading into a closed-loop precision system built on measurement, validation, and disciplined iteration.
