Need some tips on cleaning the Remington 742. This was my dad's rifle and has been passed to me since his passing a few years ago. I have loosened the forearm screw and slid the forearm forward just a little bit. Things looked kind of dry in there. After I clean it real good I may take it on a few hunts and take a deer with it or it may become a "safe queen." Any tips or suggestions would be appreciated.
