Damn, I wish I could hit the LIKE button 2 dozen times.This is the most over though topic in the firearms world.
Guys that can do ballistic dope in their heads, hand fit 1911 parts, load custom ammo, lose their shit trying to buy oil for a tool.
Most gun oils ( Rem oil, Hopps) are just mineral oil.
Gun oil needs to provide lubrication and corrosion protection.
Its not magic.
My oldest gun is my grandfathers Winchester 1873 .32-20 that he bought new. I don't know what superballstic snakeoil was the fad at the turn of the century, but I'm going to take a WAG and say being a farmer he didn't use it. It wouldn't surprise me if lard or tallow were used at times but that gun being in the family for over 123 years still functions and shoots like the day it was manufactured. I still maintain that it's not what you use but that you use it.
