Bedding has two meanings...
bedding normally refers to removing wood to seat the action with minimum clearance around the barrel and action.
Second, "glass bedding" reference to additional clearance with a "epoxy" based compound to take up that extra clearance allowing the action and some of the barrel to be fully bedded and resist flexing.
Are you handy with your hands, it maybe a nice WINTER project to do.
Some people feel intimidated and let a good gunsmith deal with it, the cast is variable on complexity of the action.
Hope this helps.
