With the action screws, get lots of wax on the screws and into the holes in the action, then 6 hours after bedding, crack the front screw and thread it out and back in. Then do the same with the rear. This ensures easy in and out.If this is your first Ruger, I would do the rear tang first, then do the recoil lug and front inch of the barrel.
Do not pop the action out of its bedding for at least 24 hours, I usually wait 48 hours. They come out much easier when the Devcon is properly hardened. To release the barrel, do not tap straight up with the rubber mallet like you do on a 700, you need to consider the recoil lug angle. A layer of electrician tape on the front of the recoil lug helps a lot. Make sure you wax, buff, then wax and buff again EVERYTHING metal on the gun, including the bottom metal. Devcon will go lots of places you did not expect it to.
This is a lot better video of doing a 77.
