The number of handle-pulls you have to make to complete a round of ammunition is probably the biggest difference.What is the difference between an Indexing Turret and a Progressive?
As always, there may be exceptions/qualifiers***, so 'In general',,,,,
In general, a Self-Indexing Turret is basically a single stage press that incorporates a rotating die assembly that advances to the next die when the main operating handle is cycled.
In general, a Turret press is basically a single stage press that incorporates a rotating die assembly that only advances when you physically move the die assembly, regardless of how many times the main operating handle is cycled.
In general, a Progressive is basically a single stage press with special shell holders capable of holding multiple rounds on top of the ram. It does not incorporate a rotating die assembly, but instead incorporates a rotating shell holder assembly. Shell holder assembly advances 1 station every time the main operating handle is cycled.
*** I consider the press shown in the link below to also be a Progressive, but it has neither a (traditional Home-Reloader type) rotating shell holder nor a rotating die assembly. Heck, I don't see an operating handle either!!
