Toby. Many thanks. I've got some of Peter Dysons browning solution and another browning solution from a gunsmith mate..I wonder if those will do.

Are you saying that you boil the barrels without being plugged and then dry them after each boiling session?

I do have the Angiers book but a friend has it for reading! Doh! Will check the pages out you suggest my friend and many thanks for the reply.
