Okay, so most of us probably bed our actions without the bolt in place. I know bedding with the bolt in place could be a bit more difficult to keep the mud away from the bolt, but probably can be taken care of with some more tape.
My point is, wouldn't having the bolt in place put the action in it's real world stress, this way when you bed it with the bolt in place, if the bolt wants to move the action shape ever so slightly it is not fighting the shape of the bedding.
BillPa, have you ever indicated an action with and without the bolt in place to see if things get moved around, by the way my actions are trued and timed by Fred, maybe this helps remove my above concerns.

What do you guys think?
