I use Hornady and Dillon spray...essentially the same stuff. I use it on straight cases and bottleneck with carbide dies. Even makes for less work with the Dilon presses. Case go in a shoebox size plastic container spray..shake spray again...leave overnight then load after drying... wet alcohol does not lube case. I do use Imperial for rifle cases loaded on non-progressive presses. I still have some small bottles of OLD CH lube I am pretty sure contain STP. Bonanza used to sell small containers of pure lanolin with no additives that worked very well... but my wife found 'em and used 'em all up on her skin. Her skin is still pretty soft for an older(than me) woman...Hmmmm I could pay for that
