Re: Man...I am bummed (lost a good stock)
There are several release agents that really work and will never fail. Before applying release agent, spray the entire action with brake clean. Then I use Brownell's Accra
Release and give the action two coats, one coat will stick to the bedding and the other will stick to the action. Be sure to spray the release agent down in the chamber, etc. When I remove the action to the stock, I use the brake cleaner to wash off the release from the action...easy. I have bedded many, many rifles using this technique and have not stuck a single rifle.
It is also advisable to spray the screws with brake clean then release agent also. Accra Release will never fail you, and I use the type in the spray can...easy...easy...easy! I have used Marine Tex, Devcon, and Bisonite with the Accra Release.
If I did not have Accra Release, I would use paste wax, but what a pain to use compared to the spray Accra Release!
I did stick a 7 Mag with Pam and the forearm broke off when I tried to get it out. I did not use two coats and I did not degrease with brake cleaner before I used the Pam(first rifle I bedded).
This ain't rocket science...good luck!
