Blue Soot?

AA2520. About 20yrs old. Thoughts? Full power load.

Blue soot is not going past the neck/shoulder junction, that i can see. Seems ok.

As for the color, i don't care. Accuracy first.

I have been removing soot using fine steel wool on neck/shoulder area. Then wipe whole case with rag. Ready to start reloading process.

What are the lines from? Neck turning? Do they catch a thumbnail? If yes, i may worry more about cutting to far into the shoulder.

New brass I don't think I sized all the way down since I didn't have to bump a shoulder. Or new chamber feature.
