Interested in hearing other’s answers. I have been doing some research on this the last few days. I was interested in why a rifle like the Barrett Fieldcraft was fully bedded. It seems the consensus is longer, thin barrels ( FW/MR and similar) may benefit from full length bedding due to the stock and barrel acting as one complete, stiff unit. It will not take out the vibration but will change it so there’s less distance away from the node (may not be saying this correctly). The frequency of the vibration will be shorter and more intense. Stiffer, heavier barrels do not need the additional support and can be free floated. In either scenario you should be able to find the node and a good load with a little a experimentation.
