Too many posts and I just don't have the time to read them all.
Just two points.
1. I stuck at least one case with just about every type of lube you can think of and maybe some you haven't. After all, I've been reloading sine 1954. Stuff happens.
2. Imperial is sold by Redding. RCBS has their own formula. What makes anyone think they'll say something nice about a competitor's product? Probably 90 percent of all my reloading stuff is RCBS and I like their products. But since I started using the Imperial, I've definitely has less stuck cases than with any other lube I've tried.
