Glad it looks good, what did you use to clean?
Caliber? The fast movers will leave copper, anything slower like 308, 30-06 don't leave much if any.
Carbon tends to be more the norm. It really sounds like the brew you mixed up was the cause of the corrosion or appearance of (muddy looking stuff is metal though it does not have to be much).
Lot of debate on cleaning, I know some barrel shoot dirty, but nor4maly 50 rounds is more than enough reason to clean.
Hunting wise if your rifle settles in after X number of rounds then its better to hunt with it a tad fouled to ensure consistency.
