The RCBS Pro Chucker 5 Auto Index Progressive Press features five-statin automatic indexing for maximum production, with a load rate of 600 rounds per hour (pistol). The quick-change die plate allows fast caliber change-over for superb efficiency. Standard primer pick up tubes are used with the safety-shielded priming system. Spent primers are dropped from the bottom of the press for capturing in a trash can. The powder measure is fitted with Quick Change metering components that allow you to drain powder without removing the measure from the press. Quickly swap out preset metering screws for dispensing the new power. The Pro Chucker 5 is the first progressive press that can be converted from five to seven station operation.
