Bolt and locking lug lube?

I've been using just regular gun oil. One time a rifle came back from the smith with grease on the lugs, never thought much of it. Can anyone let me know the advantages of grease over oil for the locking lugs?

Grease has more adherence and lubricating qualities. I use a heavy sticky grease used for lubricating dead centers in a lathe.

Agree with Guntech. Also most people over oil, on rifles that have a front action screw located and open to the lug recesses the oil has a habit of weeping down through the threads and getting between the bedding and the receiver.
 
How much grease do you apply and where? Do you apply on the front and rear as well as the top of the lugs?

The rear of the locking lugs that contact the locking lug recesses... at times they are under a lot of pressure, especially so with hand loaders... dry lugs can become hard to open, easily gall and become an ugly mess. Just a little grease...
