I agree with the studsvs screws to place the action in the bedding material. I used a large rubber band to compress the action in the stock, and the tape just like you did to center the barrel out at the end of the forarm.
One thing I didn't see mentioned, I use a toothpick to force epoxy into the drilled holes, so air isn't trapped keeping much of the epoxy from filling the holes.
I also don't like to see the wood thru the epoxy, behind the lug I would have at least drilled 3 or so holes and lowered most of the wood so a large 1/8 " thk epoxy pad would be there, vs thin epoxy over wood, even though a laminated stock is probably epoxy filled and harder than walnut.
