The only really good way to hone a tube for us amateurs, is to lathe turn a brass rod to fit the comp tube and spin it in the tube covered in fine grinding paste and oil.
It works, but is a bit more tedious than using a flexible cylinder hone.
Flex hones are notorious for causing uneven wear...
Using copper instead of brass can a good idea. So long as it’s moved in and out while turning, in order to keep the paste from clumping.
