While reading my Dillon 550 and 650 reloading press manuals it says to use 30W oil to lubricate the ram and pivot points. It also warns against using penetrating oils (which I had been using before reading the manual, duh). The manual did not specify to use detergent or non detergent oil. So I had an old bottle of 30W Non Detergent motor oil so I used that to oil the ram and pivot points. What I soon observed is that the oil remained in place on the ram where other oils would get scraped off in a few dozen strokes of the presses. When I came back weeks later the rams were clean, rust free and still visibly and adequately coated with oil. When using other oils, the oil would turn black on the ram but the 30W remained super clean.
This got me thinking that I should try this same oil on my pistols. Seems I've used about every popular gun oil on the market. I have an Atlas Titan pistol that has some sort of black coating on the exterior of the barrel. What ever GUN oil I put on the barrel, it beads up like water on a waxed surface and then is quickly scraped off in a few cycles of the slide. I used the 30W ND motor oil and to my amazement, no beading up and it stays in place even after several hundred rounds. It doesn't get scraped off the barrel like the gun oils do?
FWIW, I've used the following gun oils: Lucas, Slip 2000, Weapon Shield, Ed's Red, Mobil 1, Rem Oil, Wilson Ultra, Stihl 2 cycle oil, Marvel Mystery Oil, and a host of others.
So, oil experts, what's the deal? Why does this ND 30W seem to stay in place so amazing well and the gun oils are gone?
