I may as well wade in. I'm the guy that likes my cases pretty. Start with walnut and add dryer sheets to help control dust as mentioned before. Use used drier sheets for this as new ones seem to leave a film on the cases. Then it's corncob with polish to really brighten them up. Add more polish about every 2nd or 3rd cycle. Adding too much polish makes the cases kind of gummy. I bought the media from Midway probably 10 yrs. ago or better in 18# boxes. Polish is Frankford Arsenal from Midway. I bought the large bottle and will probably end up leaving it to my son-in-law in my will. A little goes a long way. Just now using the last of the media, but I'm not a high volume loader. When it comes time to re-order I'll be gong here.

I run each batch for 3 hours. Probably more than needed but I use a timer with either 1/2, 3 or 6 hours shutoff. http://www.amazon.com/Belkin-Conser...UMS0/ref=sr_1_5?ie=UTF8&qid=1334768612&sr=8-5
Still won't get the primer pockets or interior of the cases clean, but once it's loaded they look so good. Added benefit of using the corncob with polish as the last step is the cases go through the re-sizing die with very little effort.

Has anyone here used the walnut shell media from Harbor Freight to polish their empties? It seems like a pretty good price. I'm not sure whether the coarse or fine would be best for polishing brass.
