I started bedding rifles in the 70's and learned from old guys who were real gunsmiths, with that said it really isn't complicated, just tedious to properly prepare. I found the Brownell's spray release agent to be good, I use studs in the receiver for alignment instead of trying to install receiver screws after the compound is laid, be sure and coat the studs with the release agent and do all that first to give it some time to set. I use 60 grit paper to rough up everywhere I want my bedding compound to be so it has a good bond. Open the recoil lug recess a little and rough it. I tape the front side of the recoil lug and tape the sides of the stock as well as the tang area. Lay a piece of painter's tape across the tang area, set the action in the stock and use a razor to trace the tang, remove the action and the center cut of tape and you have a perfect match. Plug or tape the pressure relief hole in the side of your receiver, I tape the receiver above the stock line which aides in cleanup as well as the inside of the magwell. Marine Tex, Devcon and Acraglass in its various forms all work just fine, some require more mixing than others. If you're at all capable with your hands and have patience, don't be afraid to do it yourself. Like others have stated, watch several videos, I learn things all the time that I just never thought of but someone did and put it out there. If it's better than my old method, I use it.
