I have never tried wax or powder. I have a bottle of One Shot and used it once. I have been using the RCBS liquid on a pad for a long time with good results. I use an old cleaning mop or a bit of cloth on a wire to apply some to the inside of the neck. I tumble as the last step in case prep to get the remaining lube off the outside of the case and out of the neck.
I can easily tell when the lube application is getting to be too light by the way they feel in the die. I do not stick many cases and have not dented a shoulder from lube in decades.
I have loaded many Federal cases with no more problems than with most other brands.
