I have never used wet/pins tumbling and will never use it! I bought some 327 Mag cases over the internet from someone that had used the water/pins method! After two broken decapping pins I inspected ALL the purchased brass and found enough pins logged inside the cases to fill 1/3 of a small pill container! I have used corn cob and/or walnut shells with Nu Finish car polish in a vibratory tumbler for over 40yrs. The brass is clean and slippery making it very easy on the dies and reloading!
