RCBS Case Master / Runout Gauge

RCBS Case Master / Runout Gauge
With the help of the CaseMaster testing device, you can check many important case dimensions with just one device. Among other things, you can measure whether the case mouth is concentric, whether the seated bullet is exactly in the case, whether the wall thickness of the case is correct, or whether the desired overall length of the case matches the actual value. All mentioned measurements are very important details for a precision shooter during the reloading process. Accuracy: 0.001 inch Measurable case dimensions (including dial gauge): Concentricity of the case neck. Concentricity of the bullet (runout). Case neck wall thickness. Case length. Furthermore, there is a probe to detect case splitting early.
