RCBS Case Master Gauging Tool$180.74
Availability: In Stock
The RCBS Case Master is a dedicated concentricity gauging tool built for handloaders who demand precision ammunition. Whether you're chasing sub-MOA groups or simply want to catch developing case issues before they become problems, this multi-purpose instrument catches problems that matter: neck concentricity, wall thickness variation, case length, and run-out. It's the kind of tool that separates careful reloaders from lucky ones—especially when you can spot impending case head separation before any visible signs show up on the brass.
The Case Master reads directly on an included .001-inch dial indicator, giving you the precision feedback you need to sort quality brass from brass that shouldn't be reloaded. The adjustable V-blocks secure cases firmly across a wide range of lengths, so whether you're working with pistol or magnum rifle brass, the gauge handles it. The compact footprint means it doesn't hog bench space—something worth appreciating when your reloading setup is already crowded with essentials.
If you're serious about consistency, case concentricity matters. Runout, neck run-out, and wall uniformity all affect how concentrically a round seats and fires. The Case Master gives you the data to make smart culling decisions and understand which brass is keeping your groups tight. It's a straightforward, mechanical approach to a critical measurement—no electronics, no guesswork.
