Ever seen a spot like this in a barrel?

New Savage 6MM Creed. I cleaned before shooting and cleaned after I shot 2 rounds thru it to see if it went away. I sort of don't think it's copper. What are your thoughts?

Looks like a stain. Run a couple dry patches through and see if it's still there.

Yes it's still there. Looks like it's on top of the filling in the first picture.

Clean that copper spot out, should be clean then…

Don't suppose you looked at it prior to shooting it? Looks like you should have felt it during cleaning the first time. I'd think it would have snagged a patch if it was there prior to shooting.

You can try this. It had my 6 Dasher barrel so shiny had to turn the light on my bore scope to low from glare.not sure it will get it but might be worth a try
