What type of press do you use (please note if you use a bullet feeder and or case feeder)and what is a realistic number of rounds you could do in 1 hour. Primer tubes loaded. This is the first time I sat down and ran the press for 1 hour straight under a watch just to see my real round per hour count . Dillon 550 9mm. Six primer tubes pre-loaded. I average 400 an hour if I go for the whole hour. I average 12 to 13 minutes per hundred plus time to put more primers in and empty the finished bin. Wanna kill these ads? We can help!
