for me the application of One Shot is why i use it.
I also have the lee wax but i like placing 50 cases out and spraying them from two sides and i'm good to go....I also dont just resize the case, i'm reforming 270 win and 30.06 into 8x57 and i relube the same case twice, sometimes three times in the process of converting once fired brass
lube once to run the brass through a 270win die to remove old primers, then its off to a wash, dry, throw the brass on the lathe to trim to right size (the reason i deprime first is that i use the lyman holder which uses a ball bearing in primer pocket to center the brass).
Once trimmed they are annealed, dropped in water, dried off again, lubed, ran through a 30.06 die to progressively stretch the neck, then through an 8x57 die, trimmed to spec, lightly lubed again, primed, powder fed and finally bullet fed.
everything is done in batches of 50 so you can see where just spraying them saves me a lot of time than individually applying lube.
