You should really find a friend that has done it before and have him help you with the first one you do. On a Savage you'll need to put modeler’s clay in the grooves of the barrel nut or you will not ever get the barreled action out of the stock. The only tape I use on the barrel is towards the end of the stock to keep the barrel aligned in the barrel channel. I also like to use brownells release agent, some people have said Pam works well but I would stay away from WD-40. There is no reason to bed the trigger guard. This has no effect on accuracy. Also you want to get a dremmel tool or something like that and open up the area where the recoil lug is, mostly an area towards the butt end of the stock. I too have heard of people putting masking tape on the bottom, sides and front of the recoil lug. Personally I put two layers on the bottom of the lug and that’s it. The reason for that is in the event a little dirt gets in there this will give you a little clearance.
