i sized some brass with the wilson die and i like the bolt closing.
i will fire some brass tomorrow and try again.....very close

Your sticking a WSM 2.10" case in a die for a RUM 2.85 case. Do you really think that the die is going to touch the shoulders.

the dia of the case is SMALLER AS YOU GET UP.... and if you read i propably solved the isse with a new 300 wsm die

Micron dies are the tightest at the base.
Make sure the extractor claw is not dragging on the rim causing your issue.

so brass fired in the fire forming gun, and then sized with the wilson die is pretty good.
i would like less shoulder set back, but it does work about 1 thou under breech and maybe 3 or so on set back.
may call wilson and see if there is an easy fix.
if i bump back only 2..the bolt will not close
maybe my numbers are off on the setback and actually the world is good
