How to Calibrate an RCBS Digital Scale
RCBS digital scales are manufactured for hunters and gun enthusiasts who prefer to hand load their own ammunition. The scales measure the weight of the gun powder that is placed in shells. The scales are calibrated in the factory prior to packaging and shipment. Over time, the scales can lose their calibration settings. To help ensure proper measurement of your gun powder, calibrate your RCBS digital scale regularly.
