Progressive presses are designed for experienced reloaders and shooters who go through more than 500 hundred rounds per week. Unlike a single stage loader, a progressive press causes many things to occur at the same time and because of this there are many more things to monitor.
There is no reason you can't start with a progressive press, but unless you go through over 500 rounds per week, a progressive press is not necessary. Setting up a progressive press requires patience and attention to detail. The Turret press is less expensive and easier to set up, and (once set up) will reload up to 250 rounds an hour in experienced hands.
The single stage press Kits and the Turret Press kits** both contain the basic elements for a complete set up. Just order the die set or sets that correspond to the cartridges you wish to reload, and for rifle cartridges, a case length gauge/shell holder to maintain correct case length. The shell holder needed for the press to use the dies is included with all Lee Die sets other than RGB.
For more information about the difference between single station, turret presses and progressive presses, please see this help ticket: Single Stage, Turret or Progressive?
If you decide on a fully progressive press for your first, we would strongly advise loading one cartridge at a time until you are completely familiar with what functions are occurring at every station. Once you clearly understand the mechanics involved, then you can begin loading a new case with every stroke and be at "full tilt".
**Please keep in mind, if you are reloading rifle cartridges on the Value Turret Press, any cases over 2 5/16" will require the auto indexing to be disabled and you will need to purchase the corresponding Charging Die if you are choosing to use the Powder Measure included in the Kit. This Charging Die is NOT included in the Kit or with the rifle die sets.
