Freefloat forward of the recoil lug. I degrease the area forward of the recoil lug, then put a piece of Duct tape down and press it firmly. Then, put some release agent on the duct tape. After the bedding is cured, just pull the duct tape out, all epoxy forward of the recoil lug will come out easily. I put a 45* angle on the edges of the recoil lug with a small file as an aid in removal.
Key to a good bedding job is to let the bedding sit up a minimum of three days prior to removal from the stock, don't touch it, seven days is even better. When using Marine Tex, I give a skim coat after the initial cure.
I put pillars in all my stocks, prior to bedding, and using a piloted end mill makes boring the holes out an easy job
Remember, on actions with three screws, that third screw should only be finger nail tight, you do not want to put stress on the center of the action bending the action/
Also critical is to freefloat your magazine box between the action and the floor plate, you should be able to easily wiggle it with your finger when you drop the floor plate, the accuracy of many rifles has been ruined by a magazine box that is pushing up on the center of the action. Height of the mag box is easily decreased by filing off the bottom of the mag box or using a belt sander to accomplish the same.
Actions where the screw goes into the recoil lug should not have their bottoms floated, all others should not touch on the bottom.
