I use Imperial on my case bodies, but dip the necks in the dry moly/ball bearing dip from NECO. No expander ball drag, and easier to clean up.

I've got this feeling that Freud would have a thing or two to say to JustC!

Imperial Sizing Die Wax is the best I've found for full length resizing. I just dip my forefinger into the tub and wipe the case with it getting a little into the mouth of the neck. I try to keep it away from the shoulder so it doesn't get wrinkled during sizing. After sizing, I wip off the excess and go ahead and load the case. After I get the cases loaded, I clean them well with a degreaser so they are completely dry.

I put a small amount,(real small) on my fingers, and rub it on the case....then scrape your finger over the mouth of the case........That deposits a small amount of lube in the case mouth. But on common calibers I use Hornady carbide buttons on the decapping stems of my RCBS resizing dies. That way I don't have to worry about lube on the expander button. One 30 caliber button, can be switched to any of my 30 caliber dies, and the same with the .22s, 24s, 6.5s, etc. Grant.
