Pillar block touching the action ?

[wywindsor]

Not wanting to start a war or invade others post. I see where some like the contour style touching the action. Richard Franklin only wants flat style with very little contact. Or should you mud them in and machine them down below the bedding surface a few thousands? This would be on an octagon style action.

Flat pillars and let the bedding around the edges comform perfectly to the radius of the receiver for me...

I hold the pillars short of contacting the action, back cut the upper diameter so the bedding flows around the upper part of the pillar and then bed over them. That way, the action only contacts a single material....the bedding compound.

This is an example on a recent one:

If the action is only contacting the epoxy and the epoxy shrinks, where is the contact point of the action to the bedding?

Which is why we use epoxies where shrinkage is as close to zero as possible.
Shrinkage wouldn't be isolated to the pillars, it would be the entire bedding job.

Marine-Tex (gray) doesn't specify shrinkage but I've read it's less than 0.1%.
With 1/8" thick application, that would amount to a dimensional change of 0.0001 inches. That'll never translate to anything at the target. Much ado about nothin' IMHO.
