Barrel pitting?

[Jc85]

hey guys.
I shot my 3rd round of lead reloads the other day. Not to bad, finding better recipes for my applications, which is good.
What is bad tho, back at the house while I was cleaning I found what looked like leading, ok, no big deal just tune down the load a bit after a nice scrub. a particular part close to the lands wouldn't come clean. Looks like a little bit of bubble crud. Ill try to post some pictures. Thinking it was stubborn lead I gave it a good scrub with the brush and decided to soak it overnight, with some hoppes solvent. A little bit of crud came out that was left in but those bubble looking things are still present. I do not have a bore light so a lamp has to do. Dosn't appear to be copper fouling as I see no evidence of it being brown / blue / w/e. I don't see how my barrel would become pitted after one firing session with lead. Seeing how I meticulously maintain my firearms. I did see these before but my untrained eye didn't really know what to make of it. Perhaps it was sold to me this way. IDK! Any info or feedback on the subject would be very appreciated. Ill get to work on some pictures but no promises, Ill see what I can do. Oh I would like to mention that my hot bore accuracy is absurd. I just chalked this up to improper grip, or a **** load. but at the range yesterday, my POA was all the way left on my dovetail and POI was center mass on that target. Meaning I literally pointed my gun off target to the far left of my rear sight and hit middle of my paper. Good stuff right? Gonna head back to the bench and see what I can get photo wise.
thanks guys.

ok I tried to take some pictures. the only one that came out makes it look just like a shadow. . it is ez to miss.. What I wouldn't give for some 35mm film.. these darn newfangled digital. I haven't handled a camera since 04/ 05. when I took photography in HS and summered as a lighting guy for a friend. Ill see what my wife can do with it. She actually read the manual .

Don't soak your barrel over night in solvent. This can and has ruined barreln in my experience. If you absolutly what to do something like that, cork one end of the barrel and spray some degreaser like Break Free of WD-40 in there. Solvent is too hash and can eat the material. In the manual it states to not soak in solvent to often. This is you first gun if i'm not mistaken, The solvent thing was fime for older guns that had just a steel barrel, the guns now have other compounds in them that make them more tolerant to heat and warping. Solvent is not a good thing for long periods, a half hour is pushing it.

while I respect your feedback, I seen no danger in a one time application of hoppes. Not saying that outcome is not possible tho, giving enough time, that is after all what the solvent is designed to do. Thank you for your concern. Yes you are correct, it was my first gun. So I took extra special care of it since my purchase, somewhat babying it. Making sure to clean it every time I shot it and run some clp down into the barrel about once a month when not in use, not soaking, just light application.
Since then tho, like most people do. I've acquired 2 more firearms and more experience with their use n functions. Not saying I know all there is to know, far from it actually. But I had the same thought as you, everything I found online told me soaking it once n awhile wouldn't permanently damage it. Just clean it very well afterwards.
anyhow, that bubble crud looking stuff is still in there and I don't know what to do about it.
Id also like to add that all the info I seen points to the sigma having a SS barrel. So no nickle or any other plating for the hoppes to get under and break loose. Please correct me if I'm wrong on this point. Ignorance is one thing, only if corrected. Thanks.

Perhaps its just some really stubborn fouling. Ill go get some bronze chore boy and see what "works out".. <-- get it?
