The original CAP is no longer being produced.
We've made a more cost-effective soluton called the CAP Lite.

Small change, huge results
The research is clear – changes in humidity will alter the weight of powder a seemingly meager 1%, while also causing a massive 200 ft/s shift in muzzle velocity.
Too dry and it becomes unsafe from increased pressure.
Too wet and you lose velocity.
The CAP prevents this by maintaining a consistent relative humidity for your smokeless powder, regardless of the climate conditions of your region.

Ideal placement, maximum airflow
Our patent-pending cage keeps humidity packs at the top of the container to maximize the airflow to your powder, stabilizing moisture content more evenly and rapidly.
Lock it in
Utilizing flexible materials and a simple one-piece design, the CAP incorporates an airtight seal to maintain a consistent internal atmosphere.
Engineered and Made in the USA
The CAP embodies American engineering and manufacturing excellence. Crafted with unwavering precision using premium materials, each device is meticulously built in the USA to the highest standards.
Meticulously Crafted
Produced in small batches to ensure uncompromising quality and exclusivity for serious marksmen.
Rapid Evolution
Our limited batch production enables us to quickly iterate and refine the CAP, keeping it at the forefront of precision reloading.
Optimized grip, built to last
With a larger diameter and finger grooves, the CAP makes it easier to open and tighten your smokeless powder. Using robust PA12 Nylon that is over 50% thicker than injection molded parts, the CAP is made to last a lifetime.
Clean and easy
Replacing humidity packs is a breeze. No sifting through powder, no spills, no mess.
Cutting-edge manufacturing
The CAP is made with state-of-the-art additive manufacturing that allows shapes and material thicknesses without the compromises that come with injection molding. All components of the CAP are produced by MK Machining in Missouri using HP 5200 industrial-grade machines.
