RCBS Expands Precision Mic and Chamber Gauge Lineups

New Cartridge Offerings Include 6mm Creedmoor, Others

OROVILLE, Calif. – December 14, 2021 – RCBS®, the leading manufacturer of ammunition reloading equipment for rifles and pistols, has announced the expansion of its Precision Mic and Chamber Gauge offerings with the addition of several new cartridge options.

The RCBS Precision Mic lineup will now include 6mm Creedmoor, 6mm GT and
6.5 PRC, while the Chamber Gauge lineup has added 6mm Creedmoor, 6.5 Creedmoor, .243 Winchester, 30-06 Springfield, 300 Winchester Magnum and .44 Magnum.

The RCBS Precision Mic helps reloaders determine chamber headspace and bullet seating depth to within 0.001 inches. By measuring from the datum point on the case shoulder to the base, the precision mic gives reloaders spot-on Sporting Arms and Ammunition Manufacturers’ Institute (SAAMI) tolerance readings, making it an indispensable tool for safe, accurate reloads.

The RCBS Chamber Gauge is designed to measure minimum SAAMI specs, verifying overall cartridge length and ensuring rounds will safely chamber. Reloaders can simply drop a loaded round into the chamber gauge to see if it will fit their firearm.

Manufacturer’s suggested retail price is $74.95 for all models of RCBS Precision Mics and $28.45 for most models of RCBS Chamber Gauges. For more information about RCBS Precision Mics and Chamber Gauges, or to check out other RCBS products, be sure to visit RCBS.com.
