I received some .348 win brass that had been fire-formed out to .45 caliber. Naturally I want them back to .348 so....I lubed them with Imperial sizing wax and had at it. I lost two out of the first ten...Not so good. I decided to try my lanolin spray. Bingo! The next 20 sized smoothly and zero lost cases. My take away is that the lanolin is a better over-all lube.
