Back bore to remove pits

[Bill Murphy]

Oil soaked emery cloth works as well.

Scotch rite will mark or scratch the steel while Frontier will not.

I used the emery cloth method on an old LC 10 gauge I picked up really cheap starting with 220 grit and working to finer grit finishing with 600 grit and took out pits that looked like craters. I wasn't worried about exceeding safe barrel wall thickness because these barrels are built like a light artillery piece. Surprising that what appear to be ruined barrels can be brought back with relatively light polishing. Advantage over back boring is that yo can stop as soon as the pits are gone without worrying about taking out any more materiel than is absolulty necessary.

Do my measurements look stout enough to allow for the 220 - 600 step process?

After two rounds of sporting clays and two good cleanings, the pits in my new GH are already disappearing

i agree with mills i too have several guns with deep pitting in the barrels and they all shoot fine and i donot think it hurts the pattern...charlie

Since there is no way to accurately measure the depth of the pits and pitting almost always looks worse than it actually I can't advise for or against it on your gun but you will not be removing very much metal with the emery cloth and you can stop if you feel that your barrel walls are reaching what you consider to be the minimum safe thickness. The 600 grit cloth is primarily to polish the bores and doesn't remove hardly any metal.

[Dean Romig]

And Frontier pads removes no metal at all.

then I might expect that what you saw in the bores was not true pitting - but some spots of discoloration

I have had dirty bores that looked worse but when cleaned well showed minimal pitting -

but I also have guns with mild pitting that have been shot and cleaned for years- the pitting will not get worse- but is not going away



unless I glue emery paper to the wads

[Mills]

Might be. It looked like pitting.
