Re: Best combination of 9mm dies
If you want to use lead instead of jacketed bullets, I would suggest the Hornady seating die. Its insides are easily removed for cleaning (the lube on lead bullets tends to gum up the insides of seating dies) without tools or messing up the settings. They have a sliding alignment sleeve that helps align the bullet with the case before trying to seat it. They also have an optional micrometer seating depth adjustment. They will crimp while seating, but I don't know how easy that is with a taper crimped cartridge. The work very well crimping while seating roll crimped cartridges.
Sizing dies are much more similar between different manufacturers. Carbide or Titanium Nitride dies are best, since they do not require lubricating the brass before resizing. Pick one, they're all good.
Expanding dies from Lyman or Redding are best. They have a two stage expansion that opens up the case mouth a little and then flares it.
If you want to crimp separately after seating (not a bad idea if you have an available station on your progressive press), taper crimp dies are all about the same except the Lee Carbide Factory Crimp dies. They have a carbide post-sizing ring that irons out any case buckling that may have occurred if there were problems with the crimp. IMHO, they only do any good if you have a problem that needs to be addressed elsewhere (i.e. inconsistent brass length, etc.)
