Thanks for the interest Gentlemen, I have used scot bright in the bore already, but will give it some more work with oil. My Hollis got the same treatment and with use is getting better and better to load.
I will continue the scotch bright/WD40 and shooting it with a greased felt wad, I find that means I can keep loading it in the field with its own ramrod, I do the same with the Hollis and it seem to work well.

Cheers
Gordon
