Is this one of the reissue sporters that were made a few years back?
If so, the two rear screws are the ones used to get the action out of the stock. The front screw is a barrel tension screw that can be adjusted to put pressure on the underside of the barrel (harmonics and whatnot).
After you take the screws out carefully lift the action out of the stock. The reissue guns came factory pillar bedded so, lift strait up on the action to get it free of the stock. It may need a light tap with a rubber hammer to break it loose.
The reissue guns came with the micro adjust trigger and there is a lawyer pin that goes through the trigger assembly that limits the amount that the trigger adjustment screw can be backed out. If you drift that pin out (its a roll pin so its not hard to drift out) the trigger and over travel screws have Much more travel and can be adjusted to suit you. I've heard that people have gotten them down to 10oz but the one I fooled with was set to 2 LB with no creep or over travel.
Just remove one pin and turn the screws to suit you
