Everybody has giving you great advice but I think there missing certain things. You can shoot commercial ammo but DONT go over 175 grain bullet. Your dealing with allot of presure an you dont want to bend your op rod. There are parts to grease and part to oil. I personally use Shooters Choice grease and Hoppe's Oil. They are not hard to assemble and disassemble. If you dont have a bolt disassemble tool get one. Its allot easier than using a flat head screw driver. Get some Boiled Linseed Oil for the stock. Dont varnish the stock. Respect your fore fathers and leave the varnish for Bubba.
