A reloading machine is configured to check the length of shell cases of selected caliber against a length specification for the caliber. A shell case entering a workstation tool strikes a sleeve by end-to-end contact, raising the sleeve in direct proportion to any excess length of the shell case. A detector monitors how high the sleeve is raised and triggers a signal if the height indicates the shell case is too long. Length detection is derived from a powder measure assembly by monitoring the raised height of the powder body. Length detection is derived from a powder level check assembly by introducing an intermediate sleeve between the powder check die and check rod assembly. The intermediate sleeve is sized to engage a shell case of the selected caliber, at least when the shell case exceeds the specified length. The raised height of the intermediate sleeve allows determination of case length or identification of shell cases of excess length.
