The top presses of all time are probably the Lee single stage, the single stage RCBS Rock Chucker and the Dillon 550 progressive. The 650 is top of the line, but probably not the best press to learn the basics on.
I have the 550 and can sit down and do about 300 and hour.Dillon says more but not this boy??
If things are really "in the groove" for me, I can hit 400-420, but certainly not 550! 300-350 is about the norm.
