Also one of those “little bit goes a long way” scenarios, food grade lubricant. It’s boiled chicken fat. Usually white like lithium grease, just way easier to apply to stuff, and doesn’t get all over the place.
I am still working through my last ever (I cant find replacement) can of Lubriplate out of Newark, NJ. Picked some up when I was visiting a friend in Kearny a few years back, and I can’t find the stuff anywhere now. Haven’t looked hard online yet, but I digress.
Food grade lubricant, its not too tacky or sticky, but it sticks to what you want it to stick to. Stays there, too. Shouldn’t mess with any of the metal surface finishes, even the shell casings.
