In my Lyman GPR I use a .495 ball and .018 ticking from Wall mart. Over the years I have tried many lubes, but for the last 3 or 4 yrs I have been using Ballistol mix 1 part ballistol 3 water. I have shot 30 shot matches without cleaning. When you buy your ticking be sure and run it in the washing machine at least one time. Hope this helps.
