If you have a lathe, you can try nylon but be aware that it will take a permanent impression from the pin so I don't know if that will still provide a beneficial effect.
I'm going to see if the local industrial supply place has Devcon urethane rubber in a hard variety. That can be mixed up in small amounts, smeared in the pocket, and allowed to cure. This stuff is used to reproduce (in appropriate molds) obsolete automotive chassis bushings, for example.
I see Devcon has a Flexane product with a hardness of Shore 97 (A). That's about like auto chassis bushings.
Still looking for harder, in smaller, cheaper packaging.
(Edit) Where to get nylon stock -- hardware store, those white plastic nuts and bolts.
