I was at our clubs last silhouette match for the year today and the subject of case sizing lube came up. One person said he had just purchased some lanolin and was going to mix with Iso Heat which I stated that that was a proven method. Two other guys said that they use chainsaw oil. Now at the time, I didn't think of asking if it was chain saw bar oil or chain saw 2 cycle oil. Has anyone ever tried using either as a sizing lube? Also the thought occurred to me if either of these oils would work if mix with Iso Heat as a spray on lube like the lanolin mix. The two guys that use chain saw oil stated it was a whole lot cheaper buying chainsaw oil than lanolin, which is true.
