I have a Kreiger BBL in 22 Dasher that has reamer marks. It shows up when I resize,they are noticable with the eye but can not be detected with the "Feel" I know they are not hurting anything BUT I do not like the appearence. It is on a Panda action and I have means of removing the bbl. Can I polish these out with , 0000 steel wool, JB or ??
Thanx,
Jim:confused:
 
Ideally, I think you may have to have it set back and rechambered with a good reamer. I don't think you could polish out those marks with 0000 steel wool.

I use 320 grit with WD40 after I cut a chamber. I cut off a small section of a hoe handle and turned down a small dowel on one end of it with a slot to hold a strip of paper, I left a handle on the other end to hold. I polish my chambers to just give a slight criss cross pattern. If you can’t feel the marks, this process will take care of your problem. 320 grit with WD40 will give a very good slick finish. Just chuck the barrel back up in a lathe, dial it in and polish the chamber.
 
Different Opinions

I do absolutly nothing to a chamber after reaming, the finish that the reamer leaves, (if used properly), seems to be a good compromise between easy extraction and the cases gripping the chamber walls so you do not get a tight bolt when shooting in the upper load window. It has always been my experience that a super polished finish in a chamber is not a desireable trait.
You do not like the appearance of the reramer marks?? But as you say, they are not hurting anything.
So here is what you want to do. You want to take a perfectly good chamber that has correct dimensions, is working fine with no problems, and then you want to "fix" something, that is of no consequence, by "hand polishing".
I say just leave it alone, shoot the barrel out, and not worry about it.........jackie

Thanx for all the replies. Jackie I agree "If it ain't Broke ,Don't fix It" I will leave it as is. The rifle shoots better than I can.

If you are just "seeing" rings in the brass after full length resizing, but can't feel them, this is normal. These are just the tool marks left by where the reamer was ground. Even if the reamers OD was honed by the tool maker there will still be some visible tool marks.

Like was said above, if it is causing no problems in extraction, "let-er-ride".

Now, if the grooves are detectable by feel, you may have a chamber that was cut by a dull reamer. Again, if these are not deep enough to interfere with extraction, I'd still not worry about it.
 
If you want to make it look good without changing any dimensions, use a piece of Scotchbright wrapped around a wood dowel. I would rather use that instead of sandpaper.
