The engineering behind the numbers.

Precision in ammunition inspection comes from the design decisions nobody sees: how a decision is made when a reading is marginal, how a feed recovers from a jam, where the data goes. These are the ones that matter. Every one of them serves the same end: a compact, high-performance machine that keeps running, assembled in the United States.

Six Sigma design standards

Every system is designed using Six Sigma methodology, so each step in the inspection process is specified, measured and controlled. The result is equipment whose performance is known before it ships, not discovered on your floor.

Twelve sigma reliability

The weight inspection platform is designed to twelve sigma, which works out to roughly one component or round weighing a tenth of a grain outside its limit and still passing in twelve billion. For practical purposes, nothing out of spec gets through.

Firewall decision logic

Patent-pending firewall technology means a defective cartridge or component can never be passed as good. The logic fails safe: when a reading cannot be trusted, the part is rejected rather than assumed good.

Headstamp recognition

AccuSort images the headstamp of every case and matches it against a library trained on your own brass. A headstamp the library has not seen pauses the machine for the operator and is added, so the library grows with your work: learning mode first, then automatic. The recognition software is not the limit; a modest computer classifies several hundred stamps a second, and the mechanics set the rate.

Optical measurement and machine-learning inspection

AccuVision measures every critical dimension of a part optically and compares it to your limits, the way a case gauge would, on every round. Machine-learning defect detection runs alongside the measurement to catch dents, dings and surface flaws that a dimensional check alone misses.

Lights-out operation

Anti-jam feeding and hopper options let a system be loaded once every eight to twenty-four hours and left to run. If a problem does occur, the optional wireless connection and phone app notify you, with counts by weight class and cycle-complete alerts.

Every round recorded

Weight inspection systems store a record of every round for the life of the unit, with up to 25,000 preset configurations for instant recall. Data output is Six Sigma compatible, the app gives you weight data by lot number or by individual round, and where requested a remote data feed sends results to a central system as they happen.

One-touch operation

The new simplified interface runs a system with one touch. User access levels keep configuration changes with the people who should make them, and a manual weigh mode needs no setup at all: enter a high limit and a low limit and start weighing.

Modular, expandable

Two-output pass/fail systems upgrade to eight-output sorting. Conveyor connections tie inspection directly to commercial loaders. Feed, sort, weigh and vision all share a platform, so a line grows one module at a time.

The match-grade method

Combining sorting and weight inspection lets a manufacturer produce match-grade ammunition without match-grade component prices. Brass is sorted by headstamp and lot, brass and projectiles are sorted to a tenth of a grain, loaded with an exact charge, and the finished rounds are sorted again by total weight. Like-weight rounds are boxed together.

Because the brass weight, projectile weight and powder charge are all known, the total weight of every round in the box is consistent, which is what match consistency is.
