Here's one I found on the web.
I did it to my inaccurate Ruger 77/22 Hornet, but haven't shot it yet.

The recent thread on Fluxes reminded me of a rifle bedding trick learned from the Kiwis at the 1979 Palma Matches at Trentham (Upper Hutt), New Zealand
Flake Rosin, dissolved in alcohol until it is a syrup, is handy substitute for epoxy bedding of actions to stocks, and has several advantages over epoxy. (Dissolved rosin, of course, is nothing more or less than old-time furniture glue.)
It works very will, particularly with wood stocks. It will not fill large gaps like epoxy will, but works better than epoxy where a fairly close fit already exists.
To use it, simply pour some dissolved resin into the area of the stock you want to bed, and assemble the barreled action to the stock. Wait overnight for it to thoroughly dry before disassembling or shooting the rifle.
The advantages are:
No release agent is required. To disassemble the rifle, simply hit the bottom of the barrel a good whack with the flat of your hand. Most Kiwi and Aussie shooters I knew did not disassemble their rifles between shoots, because doing so broke the bond between stock and rifle. They were essentially shooting "glue-ins", with the advantage that they were easily "unglued". (An alternative method of release is to put a large pin punch in the bottom of the front action screw hole and give it a tap with a hammer, on actions with a "blind" hole.)
The resin is thin enough to easily penetrate wood some distance and strengthen the area under the bedding. It shrinks VERY little and fills every pore of the metal/wood it touches … producing a good bond unless the action is really highly polished.
Each time the rifle is disassembled, a thin "paint" coat of rosin can be reapplied to the existing bedded area. It will "melt" the surface of the resin already in place, so the bedding doesn't get thicker …. it just re-adheres to the action as it dries.
Available at real hardware stores as "flake resin" or "flake glue" (make sure you don't get some modern, compounded substance), this stuff is CHEAP. Enough for seventy-seven rifles will cost you a few bucks.
The Kiwis/Aussies considered this one of their "accuracy secrets" for high-power competition. Maybe it will work for you …
