I bed all barrels 1 to 2" ahead of the lug. I have tried it both ways, light or heavy barrel, I like the results better bedded that way. Now whether the barrel is free floated, fully bedded or has a pressure point near the end of the fore-end, gets decided through experimentation. Many really light, wippy type barrels benefit from full bedding or at least a pressure point. I start with the barrel free floated, then try pressure point next, if the barrel still wanders as it heats I move to full length bedding of the barrel.
