Use a dremel tool with one of their carbide tips and clean up the old bedding job. If it has been done with Devcon or Jb weld use a carbide cutter, and you may need more than one to get the job done. Use a good bedding compund ( acura-glass in the paste form is superior). Place a release agent on all the metal parts. Birchwood casey gun stock wax is excellent. It is in an almost liguid form and apply it with q-tip. Put the bedding into the stock working it in a circular motion similar to welding, this will prevent air pockets in the bedding. Use bedding screws and put the gun together without screwing in. Wipe excess bedding off around the gun, and take out the bedding scews and replace with the original screws. Remember to put release agent on the screws, wipe out excess, turn gun trigger guard up, and hang 10 lbs of weight off the end of the barrel till the bedding is done (24 hrs) should free float nicely. With the dremel tool clean up any bedding that is not quite right. If the bedding is tight and you are having trouble to get it to release, put it in the freezer for a while and take it slow. I have done many hope this helps you out.
