I use RCBS II with the pad. Dry brush the necks with nylon brush. Just reformed 50 300WM cases down to 7mmRM. No harder than resizing fired cases. Use Imperial lube on my neck turning mandrels and Expander mandrels. Clean it up with 91% isopropyl alcohol. Use Q tips in the necks and roll the cases on a wet paper towel. I have used the RCBS/pad for 45 years. Still using the same dies that came with my press in 1974.
