RiverRider, you can certainly size in a Lyman 450 if you want, it's just slower and doesn't always size as straight. But it will do the job just as well as it does for lubed lead bullets.
I have found one situation where it made sense to lube powder coated bullets - when pushing soft bullets at high pressure for hunting loads. I was getting lead rings in the chamber at the case neck and lube grooves were collapsing, but adding lube fixed it. Velocity was too high for that alloy without powder coating. With that said, it was a special circumstance and I don't normally bother with it.
