If it's raw, a flexhone will probably do what you need but the time it will take (and sometimes quality) will change depending on what you're using to drive the hone. A hand-drill will work but take forever. A faster spindle will make life easier. You also need some lubricant, in absence of anything else you could use some tramp motor oil as long as it didn't have any debris in it.
The company brush-research has some good resources if you can find them. One time I posted a random honing video on youtube and somebody from the company contacted me out of the blue with some pointers...hah
We just did it. the previous owner of the gun painted it and didnt tape off or something and there is debries and peice of something in there that my hammer hits when cocking makes it stiff. We used 3 flex hones the 2 abrasive 600 and 800 and then the *silicone?* one. Drill press and he has some special mineral oil that did the trick. Now the tube is amazingly smoother than my other cockers
