I hadn't seen or heard of that. Thanks for the tip. I like a lube I bought that comes in a little tin, texture like Chapstick, that requires a very minimal amount to lube the cases. You have to put it on with your fingers, so it's a bit messy, but there is essentially no chance of fouling your powder (still have to be careful about contaminating primers because I think it's petroleum based).
The RCBS stuff works, but it's way too easy to put too much on and either foul the powder or dent the case neck with rifle cases. At least it is for me. :-(
