I've had one of these with the bushings on back order with Graffs for about 6 mo's. Since I put these on order I've seen some posts where people are saying they still have to use the redding body die. I'm assuming you can go a good number of loadings before having to break out the body die?? If not maybe I should just stick to the lee collet die and body die I have....but I wanted to make things really simple in one stroke of the press without lube. Any input from bump die users please??
