Anyone done this? I've heard of it, but have never done it myself. I just got through resizing and prepping 2,500 .223 cases for reloading. I've run them through the dishwasher twice thus far. First to remove as much dust and dirt before I resized them, then after resizing to remove all of the case lube. They are clean and dry, but tarnished. Next I'm going to swage out the crimp in the primer pockets because most of them are military cases, then trim them to length in my Giraud Power Trimmer.
After that I want to give them a final polish before running them through the Dillon. They aren't dirty enough to warrant using a wet Stainless Steel Media tumble, so I'm going to go with ground corn cob with a polish. I normally use Dillon Rapid Polish with good results. It's a fantastic product. I've heard that Flitz Metal Polish works great for this also. I tried a dab on a paper towel, and in just a couple of passes the case was as bright as could be.
I have a 2 pound can of this stuff I bought from Midway because it works so good on Stainless Steel handguns. I thought of putting some in the ground corn cob to really brighten up these military .223 / 5.56 MM cases I'm currently working on. This stuff has the consistency of toothpaste. I don't know if it will get spread around like the liquid Rapid Polish will, and I don't know what to thin it out with? Perhaps I could just place small pencil erasure sized globs of it all over the media before I dump in the brass and fire it up?? Anyone done this, or have some suggestions? I'm real anal about having nice looking brass, which is why I bother with it. Bill T.
