I have been using Imperial Sizing Wax on the case body for at least 3 decades now, probably longer.
I lube necks with the pill bottle, ¾ full of #8 shot, with a tablespoon of powdered graphite in it.
Just dip and twist the neck in the shot....you're done! It's dry, so no need to remove later.
Since I loathe all spray on case lubes, this is my chosen method, and it really works.
I FL resize, form different cases, etc with it.
Redding now produces the Sizing wax, so it is relatively easy to find.
A little goes a long way, as well....one large tin lasts me thousands of rounds.
Regards, Dave.
