...I have the Hornady Custom Dies (2 die set) as they were the only ones available at the time. I have had no issue with them, especially as I had to convert 300 Starline 6.5 Grendel brass to 6ARC brass (no 6ARC brass or ammo was available to me).
...The Hornady sizing die "appear" to be FL/SB die as the case web will be sized down to 0.438", just below the SAAMI spec of 0.4410" (at least MY die does). This is with the die set to just barely touch the shell plate of my Lee LoadMaster, no "cam-over". At this setting the shoulder will bump to 1.188", near the middle of the SAAMI spec range of 1.183" min - 1.190" max. Each chamber will differ so you will have to re-measure your fired cases to get a final die setting.
...I did add the Hornady Micrometer Adjuster to the seating die. The seating die comes with the stem for A-Max/ELD-M bullets, they offer a separate one for A-Tips. I found it works with Berger Classic Hunters, VLD's and Nosler RDF's as well as the Hornady VMAX bullets.
YMMV
