Paper patching to improve a bore
OK I remember a thread from years ago where a member (NoBade?) Had if I recall a .303 that he called the sewer pipe. The thread details his adventures on making it shoot and I beleive he said that the bore was actually improving and being polished a bit.
My particular case is I have a Rolling block carbine that I am trying to make into a walking around woods gun for popping hairs and Ptarmigan and the bore while not shot as it has strong rifling the muzzle is not worn out it ( through a bore scope) looks like it was finely rusted and the tops of the lands are pitted. Which makes it foul super badly.
I wondering if it would be possible to paper patch the 7x57 and maybe get it shooting enough to preserve this old girl without having to re barrel. To that end what would I patch to ? Bore size ...groove size ? This one seems to run a slug out at about .285 ....
