Pick your poison. Honestly, out of all 3 of the Wilson options, I prefer the standard dies with the micrometer tops. They have 1) standard dies, 2) micrometer tops for the standard dies, and 3) micrometer dies. The difference: the standard die is just a solid steel body with an adjustable seating stem in the top “ram,” and the corresponding micrometer top upgrade has the micrometer collar in the top ram itself. The micrometer die uses the standard top, but has a micrometer collar threaded onto the die. Admittedly, I only prefer the standard+micro top combo because of how it feels in my hand, AND typically it costs about $10 less than the micrometer die. Any of the 3 options will make ammo of the same high quality and low run out, I just like the standard + micro top the best of the 3.
I typically order my Wilson dies from Gunstop.com. They seem to have more stuff in stock than most places, and often lower prices. Seems everyone is always sold out of Wilson dies, but they tend to have what I need, when I need it. The website’s kind of clunky to browse, but it’s easy to search.
