I have used Pam as a release agent for bedding a Lee Enfield forestock and the recoil lug on the Savage I want to bed properly now - it worked extremely well too!
Where did you get your screws from?
Just used the ordinary action screws that came with the rifle. I notice it's not recommended practice but I had great success. I sprayed the pam into the screw holes as well as coating the entire screw. I must admit I was a little leary about doing this and that's why I turned the screws occasionally. Probably didn't need to.
