RE: Cleaning Brass
soaking your brass in some white vinigar will clean em up pretty nice... for me i resize and deprime.. then toss em in the tumbler with a mixture of walnut and corncob media.. sometimes i'll add some polish... i always clean primer pockets with a brush, just to clear em out and make sure no media is lodged in the flash hole... mine don't seem to tarnish up FWIW... but most of my brass is nickel plated... cept the 35 Whelen AI...
