During general cleaning/maintenance, excluding the barrel of course, where should oil be used, and where should grease be used? I tend to only want to use oil, but should I put grease on the bolt rails and other parts?
I grease loose-fitting moving parts- like slide assemblies.
My bolts slide pretty loosely in their actions, but if they didn't, a little grease there would help.
IMO, whatever you use it's important not to overdo it. Too much, can be worse than none at all...
Each time you fire, and you get some small amount of blowback into the action, that carbon/residue mixes with the oil. Too much, and it can even become an abrasive "slurry" that can cause premature wear on parts.
Gas guns that "crap where they eat" are a prime example.
I use oil on the entire metal of the firearm when done cleaning. Including bore and chamber and all exterior surfaces that are reachable. This is a very light film as in apply it with a wet patch and wipe it off with a dry or semi dry patch. Thats why I like a really good light gun oil. Before I fire any firearm I always run a dry patch through the bore and chamber. A good idea if your firearms sit for any length of time.
For greese I dont use a lot. Usually on semi auto handgun rails and other parts where it is high metal on metal action. But again I use it and basicly wipe most off.
It is foolish and wrong to mourn the men who died. Rather we should thank God that such men lived.

I've been using this stuff on all my bolt pieces including the firing pin spring, a little goes a long way. It reminds me of the white lithium grease I use on all the garage door operators I repair. It is also easy to clean not like heavy grease. Makes things very slick.
Gun control is putting 2 bullets in the same hole.
In summer I use the thinnest coat of automotive lithium grease on the bolt channels and nowhere else. The bolt, trigger group, magazine follower and everything else all get a little Gunzilla on them. In winter I use no grease, just Gunzilla. In really cold weather I wipe even the sheen of Gunzilla off the action. I've had Natasha out at the range at 10 below with no lube and no trouble. It's hard to bugger up a Mosin to the point it won't shoot no matter how you lube it.
+1 eagle. I use tetra gun grease, and I absolutely love it. A little goes a long way too.
I'd put a little grease or oil, whatever you like on the friction surfaces on the bolt to help it slide a little easier. Depending on how much you shoot it, or if you hunt with it or something like that would really dictate cleaning as necessary the parts you greased/oiled. Do what works for you, but there's not a lot that needs greased/oiled on a Mosin. Maybe sometimes a protective coat of oil if you get surface rust.
