Thought I would toss this in here. I had a great conversation with Robin at Redding one day (Great Guy!) He advised me that the T-7 when using Redding bushing dies is designed for the die to actually contact the shell holder and slightly cam over at the top of the ram stroke, The turret will rise a minute amount and wll level firmly on a machined surface in the rear of the turret. So don't go by the directions in the die box on die depth. They were not written for the T-7 press. Once I did this my COL's were all exactly the same to the thousanths.
