What is the best non-combustible pellet lube for use in both CO2 and sprinters?
hi - "the best" has not been determined, and probably never will until there's only one member left alive.
--anything with petroleum (or anything flammable) in it is no good for springers, and anything that attacks seals (other than eskimos or polar bears) is not good for co2
a lot of people use bicycle chain lube, which is sort of 'wax based' and some use furniture wax (like pledge, etc, which might not even contain any real wax--i haven't looked).
like a lube in a cylinder/piston in a car, a pellet lube can form a slippery surface which seems like a good idea.
also like a lube in a cylinder/piston, a pellet lube can form a seal which would prevent compressed gasses from passing it. that also seems like a good idea
a lube can also fill minor negative imperfections (recesses) in a barrel or a pellet, but can't do anything about positive imperfections (protrusions) except to--well--lubricate them
some lubes (think of extremely heavy grease in january in the tundra) could slow down a pellet.
all of them can be cleaned out of a bore if you decide you don't like them.
let us know what you find.
