Lithium gets gummy and dry in many of the thicker greases. I like Lubriplate, it does ahve some calcium but doesnt seem to harden up much. it's easy to over-lube winches. They just need a light coat. Not like they are rotating millions of times a year like a wheel
The Original Military Grease For Semi-Auto Rifles
Selected by the U.S. Military to lubricate M1 Garand and M14 battle rifles. A waterproof blend of mineral oil
, calcium and zinc oxide that has a high affinity for metal so it stays put in all weather
conditions, and lubricates even after the carrier begins to break down.
