dallen, I found that heating the part slightly helps obtain a more uniform surface finish. Hot enough to be uncomfortable to hold in a bare hand, but not hot enough to actually burn you. I used a toaster oven; obviously, your barrel won't fit in one. Maybe pour very hot water over it until it's heated up?
I also found that scrubbing the part with very fine (00 or 000) steel wool got the finish darker.

Full of ideas, but slow to produce parts
