I was just going to ask Mark what type of slide system his rail has, On mine the best stuff I have used is fuser oil for a copier machine, I give out a small bottle with every rail that goes out the door, I believe it is enough to use on the rail for a life time, But I think people must be globbing it on, It only takes a little, Coat each rail, After each group run your finger down the rails to re distribute the oil and good to go again, Re coat after each yardage (IMO), I ran out of oil a few months ago and acquired a fair amount since, I am not sure what works best on the rod type of slides, But RCBS case lube works pretty good on those from what I have heard, And that is what I used to use on mine until I started using the copier oil, Good Luck...J
