On a brand new rifle, I pull it out of the stock. wipe the outside with a lightly oiled rag. Reassemble with proper action screw torque paying attention to magazine alignment.
Swab the bore with solvent and dry.
Pull the bolt apart and clean it with brake cleaner, then lightly oil the spring and reassemble. You'd be surprised how dirty the inside of bolts can be on new rifles. Or how much grease they'll pack in there.
Then mount a scope and put it in my safe waiting for ammo to become available again.
