If I am doing lots I use the mix of isopropyl alcohol and Lanolin . sprayed on and swished around a big dollar store tub. Its more of mess to clean after but its cheap and fast. Imperial sizing wax is a great one to have on the bench for tougher jobs. The hornandy one shot works good if I'm reloading a couple dozen rounds with brass that I have previously fired. I stand them up in a plastic load block and spray away. I would say that its very handy to use but i don't feel its quite as good as imperial . I have run into stuck cases resizing "gun show" or range brass. Especially some of the military brass you just don't know what the rifle it was fired in and some chambers are pretty big.
