Specifically for a Savage Axis II however can apply to many rifles. Looking at my Axis II, seems that the trigger my guess does not really ever need to be cleaned because there really is no chance of powder getting in/on it. Unless I drop in mud of course. Really do I even need to oil it? Seems well enclosed and well, is it really necessary?

The bolt, my guess is normal maintenance would be wipe down/clean and bolt face scrub and clean good. Maybe some oil/grease on back of locking lugs and side of them? Other than that, how often would you all disassemble the bolt and clean? Seems not so often? Oil inside of bolt/spring/firing pin contact points? Just asking as I am really unsure.
