About RCM

Built by loaders, for loaders.

Rock Canyon Munitions designs state-of-the-art digital sensors for high-volume reloading. Our laser-based powder checks eliminate the problems that plague probe-style sensors — no spills, no suction, no stuck probes.

Why RCM

• Non-intrusive, non-invasive laser measurement.
• Micrometer-level accuracy on powder drops.
• Developed for Mark 7 presses by loaders who use them.
• Real-time undercharge, overcharge, and double-charge detection.
• Round-by-round data logging with exportable CSV.

How we work

Every RCM product is designed, tested, and iterated against real loading operations. We build sensors we trust on our own presses, and back them with direct support from the people who made them.
