Add me to the bedding issue list. A little talcum powder works well for the front rest. I have driven myself crazy from shooting off a shaky bench or bags. One time I was ready to throw in the towel in or my rifle down the range thinking how can I adjust the scope the bullet holes are not even touching. I pulled in the target and my sh*ty group was about a half inch so I called it done.
You can also put something on the barrel like Prussian blue or lipstick, I like graphite powder as it is a little less messy. But after a range session it will mark any contact points in the barrel channel that need attention. You could also try a shim under the barrel in front of the action to see if that makes a difference.
But first I would scrape or sand out the action bedding and re-bed and use the screws to just position the action and use a bungee or surgical tubing to put pressure on the scrim bedding, not too tight just firm. Blind action screws make this easier to do. I would probably also relieve the barrel channel a bit more mostly at the bottom rather than the edges. A laminate stock is typically stiffer than most glass fiber stocks and can stand to be neutral bedded so that is another option. It wouldn't hurt to try a temporary pressure point as well before final bedding.
Then there is always the tomato stake option, I never seem to have enough tomato stakes around.
