J-B and IOSSO bore pastes

OK guys, Thanks for your thoughts. At least I know I'm on solid ground here with the bore treatments. I'll give it a go in the next few days and take before and after pictures to share.

Re: owning a Lyman Bore Scope: Every bbl is an adventure. They all look pretty and shiny from the end, but once you get in there, it is very eye opening. Lots of "unsolved mysteries". Did you every hear of wormhole corrosion? I had never heard of such a thing.

Well, that's all for now. Ron

I promised a follow-up concerning my RWS 54 .22 caliber.

Tonight I was able to put the bore cleaning pastes to the RWS 54s .22 bbl.

Believe it or not, this was the hardest bbl. to clean in my inventory. All the rest are firearms, and even though they had glazed carbon, still cleaned up with just reasonable effort. This air rifle was a bugger!

The RWS was hard coated with a carbon-like residue. Nothing would touch it, including goo-gone and Bore-tech carbon remover. This carbon residue was ironed/burned in.

I started tonight with a nylon .22 bore brush with a single layer patch wrapped around it - coated with IOSSO compound. I worked it back and forth throughout the bbl trying to get rid of the resistant blackish coating. It helped a bit farther down the bbl, but the first 2 inches of the bbl was still very black. So then I discarded the patch and put IOSSO on the black nylon brush and scrubbed with that, paying particular attention to the beginning of the bbl. I was not making much progress at all. So now I used a well worn .22 bronze brush with J-B smeared on it -no patch. I just shoved the brush all the way through and then pulled it back. I could not reverse it in the bore for a normal scrubbing action like I did with the nylon brush. The bronze brush finally brought up bright metal, and the sharp corners of the land/groove intersection was pretty clean.

As you can see the bbl finish is not what one would call match grade - but just production grade. Lots of roughness, but no pitting, reamer marks, scratches, etc. Not bad really - I've seen a lot worse.

So now the bbl is clean, and I'll put a patch with Lock-ease or Dri-Slide through it to provide some initial lubrication for the first pellets. That's what a lot of benchresters do.

So if you think felt pellets, goo-gone, or other pellet bbl cleaning techniques are working, I suggest buying a Lyman bore scope.

You will find that every barrel is an "adventure" when you look inside it. Believe me, as I have Harts, Kriegers, Wilsons, 40Xs, etc. All bbls look shiny from the end. But the Lyman will reveal the real condition. Just my 2 cents.

Here's before and after pics.
