The 710 action has a Nylon sleeve inside it to reduce friction, same reason the bolt is Nylon coated. Some solvents can make the surface of the sleeve sticky. Nylon to Nylon contact slides well, Nylon to metal does not always slide well.
I would recommend using some BreakFree on the bolt rather than mess with the rifle. Once you start modifying things, it's all downhill. Or sell the rifle and buy something else if you don't like it.
