[QUOTE="ntsqd, post: 1652744, member: 93138"] I'm at 10:1 IPA(99%) to lanolin and am thinking of going to 12:1. Got all of the bits off amazon. I've only used it so far on .30-30 and .224 Valkyrie cases, but I'm liking how well it works. My procedure, as suggested by a friend who does it with Dillon's lube, is a cookie sheet (he uses a cardboard box for the taller sides) with a paper towel on it that the cases are laying on their sides on. I use a pump spray/mister bottle set on mist. Gently but thoroughly mist the sides of all cases, then gently shake the cookie sheet to roll the cases around. Give the IPA a couple mins to leave the scene and then start sizing. Even though I am getting it on the necks I am NOT seeing any dimpling. I suspect this is due to the puny case sizes, but I dunno. Years ago in my Industrial Tech capstone class we had to do a presentation on a manufacturing method, and then demonstrate it. I'd had a fascination with metal spinning, so I chose that. Done the old school way it needs a lube with high pressure characteristics (sound familiar?). A text on the method that I found in the school's library printed in 1943 suggested a 50/50 blend of mutton tallow and 30 wt engine oil. I couldn't get an mutton tallow (local rendering place had *just* shipped out their annual accumulation) so I had to research why that suggestion. Turns out that mutton tallow and lanolin both have proteins in them that REALLY like metals. REALLY bond to them and hang on. The other end of the protein bonds well with various greases making for a high pressure lube. I used an EP grease for the project, but that research has stuck with me for decades. [/QUOTE]
