Lanolin is used when making your own bullets, usually a mixture of lanolin and caster oil. Berger I think uses only lanolin. Only about 2 grains of lube is used to core seat 1000 jackets. But, it is not easily removed completely, solvent is used to clean the bullets.

If I were working on hundreds of cases at one time, I would use this spray, the small amount of lanolin shouldn't pose a problem.

I load at the range when attending matches. I use RCBS Case Lube II, water based, and a pad. I clean the case with 0000 steel wool, and lay 10 to 15 cases on the pad and roll with the palm of my hand, then resize. Wipes right off with a paper towel.
