JVON: I have and use both the Wilson seaters with a Sinclair arbor press, and the Forster micrometer benchrest 7/8x14 threaded seater dies. Both produce quality ammo with comparable runouts, as verified with my Sinclair concintricity dial indicator. Been using them for many years.
When I do have problems with loaded round runout, (more than .002"), it's traceable to defective brass. Some brands are notorius for having loaded round runout ( and I know from experience to never use this brass), and others, like Lapua have minimal or no runout.
I had some factory loaded 308 ammo a few years back & checked it for runout. I was getting readings of .008" to .012" from all 20 rounds in the box. It was so poor that after firing, the empty brass was thrown into the scrap can. This same company makes brass available for reloading & needless to say, I will never use it.
Start with quality brass & almost any and all seater dies will work fine.
