I suspect Lanolin is a major component of Hornady's Unique case lube they sell in little tubs. I've had my tub for probably 15 -20 yrs and I'm only 1/2 way through it. Guess I don't load lots compared to many here. Love that stuff - smells good, makes your hands smooth, pretty easy to wipe off cases and they even say you can use it on leather. It smells a little like mink oil leather dressing too but its white.
The other reason that lube has lasted me so long is that I went to carbide dies for all my hand gun loading.
