I use Neats Foot oil for full length sizing cases. It's a leather oil for saddles and such for the young chaps that may never have heard of it. An old fellow put me on to it years ago when I started reloading. I bought a one litre bottle in 1998 and have used about 100ml in all that time. It will last the rest of my life. I tend to neck size mostly. But it will still dent case shoulders if too much is used.
