If you are going turret, there ars some things you will need to buy to go with the kit. You need to get a priming system with the turret depending on what kit you get. Go with the saftey prime set up. It is press mounted, so when you go to use it in auto index mode, you can deprime and reprime without removing the case from the shellholder, and having to use a seperate tool . Also if you use this system, your powder measure will interfere with the priming tool. You need the order the powder riser. The one thing that you don't need right away, but you will want to have is the adjustable charge bar. The auto disk powder measure comes with disks with fixed cavities, and you can not really adjust and tweek your loads when it comes to powder charges.
If you can find a turret kit with the auto disk pro powder measure, get that. the pro has a wiper that scrapes the charge bar,or disk, and helps to reduce some of the variations in the charges. Alsodo not skimp and order the 3 hole press, get the 4 hole setup. You will have to use lee dies with the 4 hole press, or at least buy a lee expanding die, since with the turret press you expand the case and charge at the same time. A 4 hole press allows you to use the lee factory crimp die, which is a post seating case sizer. it helps your rounds chamber and makes them more uniform. i use it on everything i make. My 38 special rounds would barley chamber, untill i ran them through the FCD.
