Just was cleaning my SA 1911 barrel after a shooting session with my daughter and noticed some sparkles in the barrel after cleaning that I thought was dust. Well it defiantly is not dust. I can’t say that I noticed it the last time I had it out but might have been there. I haven’t had it out of the safe for a couple years. I have only been shooting cast hitek coated with it since I bought it. Powders have been vv n310?, titegroup, and bullseye.
The specks look like maybe pitting? But not deep pitting. I live in a dry part of Montana where the humidity is really low. During cleaning, I used copper choreboy for a few strokes and then hoppes no. 9. And then some dry patches until they were clean. The barrel looks really smooth looking through it, it’s just with a flashlight that I can see these specks. None of my other barrels have this.
Any ideas what it could be?
