Did exactly the same thing with same results....however some of my bullets were beyond tarnished and had reached the 'green tarnished' stage. HP's so I had the media in the tip. Media removed the green corrosion and I was left with bullets that were stained in spots and with media in the nose. I saw no difference in performance at all. (using really older forgotten about components during the so called shortage)jlow said:I've done them with corn cob media. If your bullets have an open tip, some of the smaller media will get trapped in it. Does not affect function but if you are doing this for cosmetic reason, you might not be happy..... They also do come out with compress air but it would be a pain if you have a lot....
