Hi Bob B257, when I do these at home I relieve the barrel channel for floating clearance with the action resting firmly in the inletting as it was fit from the factory. I do not shim up the action or develop a raised bed in the inletting area to carry the action higher in the stock.
Through a series of refitting, observing and slowly trimming the barrel channel I do my best to let the barreled action rest into the inletting naturally and cutting the barrel channel clearance to where the barrel wants to be.
I trim my barrel channels slowly with sand paper. I'll usually use about a 60 to 80 grit paper wrapped around a common deep well socket that fits the barrel channel the best. The deepwell socket is basically a sanding block for me.
The band of tape I use on the barrel at the tip of the forend is to help hold the barreled action straight & true in the stock as the wet bedding dries.
