I recently got a borescope, not a high end one, just one for taking a look in the barrel since my eyes are not the best anymore. Overall I think this barrel cleaned up pretty good, I have just never seen these "dot" before, doesn't look like pitting, it looks like is is a "bump" in the bore, anyone have an idea what this is and how it was caused?

One of my buddys is using CLR on a patch and he has been amazed at the carbon and rust that he has cleaned out of his barrels.
Looking at yours I suspect you may have rust under carbon fouling.
Thanks for the reply. I used WipeOut and it cleaned it up A LOT. So if it is rust under carbon should shooting a few rounds help to "knock down" some of that so that it can be cleaned out on a patch.

That's usual to take some of the fouling out before scrubbing a hard case. Easier than scrubbing so much...Originally Posted by EddieB

Shoot...clean...shoot.. clean ... and don't let the borescope make you nervous
Any follow up pics yet?
Waiting on some parts, rear receiver screw and front screw post. I think the parts shipped today, will post an update when I take her to the range.
Sounds good
That sure looks like the classic lumpy fouling left behind by cupro-nickel jackets. Pretty pernicious stuff riflemen struggled to clean until ammo makers switched to gilding metal for jacket material. Those silver looking jackets are the source. Not at all uncommon in ammo produced before the mid Thirties or so.
Took her to the range today, shot 40 rounds seems to have cleaned up a little, especially the first 4-5 inches from the throat. The groups were not the best but I think that has to do with me and issues with the stock.
