Good article, he is correct about leaving a film on the boolits.
I either pan lube or stuff Felix lube in the grooves with my fingers. Then I don't really size any lead, just use lapped out Lee dies as excess lube removers.
If I drop a boolit on the rug with all the dog hair I have the original porcupine boolits!
I keep lube out of crimp grooves and use my thumbnail to remove any lumps but always leave a film. Everything I do is very messy.
On occasion I use the lube sizer if the die is the right size.
