I have a hinged floorplate assembly on my T-5 stock that was pillar bedded at the factory and I have sinced glass bed it. I have noticed that when tightening the bottom metal down it does not flat. The front screw is higher than the rear and it has to bow down in the rear when tightened. I want to bed the bottom metal but have never done it. Since the rear area is lower than the front, just most Remington scope bases are, should I bed it like I do my one piece picatinny rail? I.E. add devcon to the rear screw area and torque the front screw?
 
My friend had a weatherby rifle with a steel floor plate that was like you describe. If you set it on a surface plate it rocked like a banana.
I straightened it out using a dial indicator so it was flat then bedded it. It looked like it was bent from torquing the action screws without support under the bottom metal.
If there is no support from a pillar or bedding material it would likely bend again.
 
Well got home, had a few minutes so I bedded the bottom metal. I've bedded 15-20 rifles and scope bases with good success but not sure how this is gonna turn out. I put release agent on the bottom metal and parts of the stock where I didn't want bedding. Put compound around the screw holes and evenly torqued the action screws very lightly, less than 5lbs.
 
Pulled the bottom metal out, and cleaned up the excess. Placed it back in and did some checking with my magnetec base and dial. With both screws torqued to 45"lbs, I loosen the front screw and the dial goes up .002 then back down .005 (.003 less than the starting point). I've checked allot of bedding and never had the dial raise then lower. Is this initial raise from the bottom metal flexing? This rifle was initially bedded and showed less than
.002 deflection. The barrel was pulled and set back and now I am having these issues.
