Back bore to remove pits

[OH Osthaus]

lately- i think more and more about adding an endoscope to my inspection tool kit

just to get a better view into pitted areas- i used one to look down into a SxS muzzleloader's tubes since I could not look down the bores- made me feel much better about the purchase

and pits are so objective- i have bought guns that the seller says the bores are great and i see pits, and have looked at some i thought were junk and someone else says "these aren't that bad"

Yes, and it's driving me nuts! I'm hearing "shoot it, just keep it at 7/8, and slower than 1200fps", and then I hear "Don't risk life and limb".

I want to shoot the gun, a lot. It is my gun, and the only double right now that's mine. I could shoot my wife's Sterly, or my son's Stevens. Don't want to; they're not mine. There's no budget to buy a different one of my choosing in the foreseeable future, so I'm hoping to find some confidence in what I have so I can enjoy it. It will always get really light loads like RST's Falcon Lite's or similar.

There are scopes that plug right into the usb port on your computor. Cheap. Stick a wite cloth in the end of the bore and then stock the scope in ghe other end. You can see everything. However, still cannot know how deep pitting is this way. But it may reveal it is not as bad as it looks.

Those scopes also work great for a do-it-yourself colonoscopy.

is that one of those "don't ask me how I know" sort of things

I have had two guns with serious looking pitting. After a few years of use and scrubbing, they are not pitted any more. Don't ask how this happened.

Can you share your process and materials you like to use for scrubbing? General cleaning by another name, or do you have a method you like for going after the bores a little harder? Thank you.

Why thin the barrels to the overall wall thickness of the deepest pits ?

It will not adversely affect the pattern. Shoot it now and see if you have a ragged pattern with holes.

I just acquired a GH that has pitting, but the minimum wall thickness I get with my Hosford gauge is right at 30 thousandths. These old Parker barrels can generally take a lot of abuse and still be sound. At least, in my experience

Wrap some Frontier Pad around a copper or brass bore brush attached to a cleaning rod clamped into the chuck of an electric drill that has reverse. Squirt or spray a solvent into the bore and go to town with the drill running it all the way in and out for thirty or forty passes in both forward and reverse. Then run a clean swab through the bore and see how it looks.

Thanks. I did get it a little cleaner with a similar process, but with strips of green Scotchbrite pads. I've ordered a Frontier pad, but haven't gotten it yet.
