I bought anhydrous Lanolin on line for under $10 for a pound (delivered) - that's enough for about 500 million rounds.
Lanolin does not dissolve in 91% isopropyl alcohol (as available at any drugstore), but dissolves easily in the cheap and widely available "orange solvent".
The solution of Lanolin in orange solvent can then mixed with 91% isopropyl alcohol without the Lanolin separating from the solution.
The ratios I used is 1:10 lanolin to orange solvent and 1:10 lanolin solution to isopropyl alcohol.
Make sure the solvents fully evaporate before sizing - the solvents kill Lanolin's lubricity and cases may get stuck in the die.
