I’ve tried just about every lube on the market as well as the lanolin mix, and what I use now is 1 ½ oz of Hornady LIQUID one shot (not the wasteful aerosol) mixed with 12 oz of red Iso-Heet. The liquid does not affect primers or powder, no post-lube cleaning required. Just a couple sprays in a ziplock bag, shake, let the alcohol evaporate for 15 minutes, and reload. Leaves a nice slick (NOT sticky) coating on the brass that stays for weeks stored in another ziplock. How I came about this is another story, but everyone who has tried this agrees it works great.
2 years ago or so, I bought a case of the discontinued Hornady One Shot case lube spray as seen in the picture below on eBay. When received, every one of the 12 bottles was empty (evaporated). Of course the seller refunded the payment and said keep the bottles. I then researched the One Shot aerosol contents via MSDS and discovered the same liquid lube formula name (patented of course so actual chemical contents unknown). The spray bottle formula from years past used hexane as the vehicle as does the present aerosol plus some "petroleum gases". Having nothing to lose, I purchased a couple bottles of liquid ($5) and some red Iso-Heet ($2) and started mixing. I tried 1 oz liquid per 12 oz iso-heet, but wasn't satisifed with the "slickness". I then tried 2 oz liquid to 12 oz and left too much residual after evaporation for my tastes. Finally used 1 1/2 oz to 12 oz and comes out prefect (for me anyway). Not sticky like the Lee, RCBS, and Lyman liquids, but you can still feel the slickness weeks later when stored in ziplock bags.
