I was going over an old American Rifleman mag I bought with some old Handloader mags off of ebay. It is dated Jan, 1949. A short 2 page "How to Reload" story had the formula in it. I have been collecting formulas and every time this one is quoted it is always with "What ever Cup Grease is" Well this author stated it as Penzoil #305 with graphite added! Now to see if it is still in production. JB
