A synthetic, light weight, automotive engine oil for lubricating the bolt lugs?
What would you use to lubricate new rods and bearings in your engine or wheel bearings upon repacking?
I am not dealing with RPM's in my bolt gun. Perazzi recommends oil for their bearing surfaces of their shotguns. Krieghoff recommends grease on their bearing surfaces. Both have a list of why one is better that the other, but both do suggest cleaning the bearing surface of either product after use and replace with new prior to reuse. I use Mobil 1 on my bolt guns and grease on my Krieghoff. I remember seeing where Mobil 1 had some anti-wear properties when used and is good for temperatures up to 500F if you were trying to melt an AR.
