I won't "skim bed" any rifle
If I am going to the trouble of applying a release agent and filling holes with clay I will then cut out the factory bed job. I then sand out all of the contact between the tang and the chamber using chalk or marksalot as a transfer medium
Kimbers all have this in common
(high spots between the tang and lug)
Dropping the action all the way down to the pillars and then re-bedding is what I like to do to stocks with pillars.
This is the start of a Kimber Montana 280AI re-bed after cutting out the slave/action factory bed job.
This Kimber's action was dropped .018 to contact the recoil lug pillar alone.
