2.5 LB Stainless Steel Tumbling Media Pins for Case Tumbling - 0.039 Diameter, 0.255 Length

For brass cartridge tumbling, this is the way to go. You need to deprime first if you want primer pockets cleaned. These pins will scrub you cases inside and out like new. Amazing how good they work. Use with hot water and lemi shine. Please have a good tub to work in when separating pins from cases. These little pins will go everywhere if your not careful. Dont try to do this in a washtub or sink without some kind of very fine screen over the drain or you will lose a bunch of them. A big magnet is a big help. They dont polish cases very bright. If you want your cases super shiny, follow up with a vibratory cleaner and add some rouge to it.

I always clean my coins that I find metal detecting in a tumbler with stainless steel media. I remove any valuable coins and jewelry first, then dump all the modern day coins into my tumbler. I add the stainless steel media, a few drops of dish soap or toilet bowl cleaner and some water. I let them tumble for at least six hours, then check on them. The stainless steel media does a great job of getting the built up dirt and minerals off of the coins, even in the little nooks and crannies. The media also cleans jewelry very well. I make it a point to keep it clean and dry when not in use. The very last pic shows coins that I tumbled for about six hours. All of the other pics are of coins and other items that I dug up while metal detecting. As you can see, most things are encrusted with dirt, grime, and mineral deposits. Cleaning the coins one a time with a brush is not an option. For that reason alone, is why I use a rotating tumbler with the stainless steel media. I’m very happy with the end results. With the coins clean, they will process through the CoinStar machines, something that would not happen if they had not been cleaned. I hope the review is helpful. Thank you.

This looks like its going to be perfect to use for brass cleaning in the small tumbler that I have. Unfortunately, the lid came off during shipping and I had to reclaim about half the bottle from the pouch that it was shipped in.

I wet tumble a lot of brass and this steel media makes light work of that. Two pounds of this media is the perfect size for my machine. I mix these pins with 4 pounds of brass and in 2 hours all my brass looks new. A must for the reloader in your life.

I use a rotary tumbler and have been using ceramic and plastic tumbling media. This is my first time trying stainless steel and it gives me a wonderful shine that I wasnt achieving with the other materials. This is a quality product, it came ready-to-use, in a nice reusable container, and Im happy with the results.

I had never used pins always, ground medias like walnut shells, these work really well and really get hard inclusions off the surface of what you are trying to clean/smooth. I was worried the harder material might cause scratches but have yet to encounter any marring.

These pins are nice. None are irrigurlars on sizes. Do a great job in the little tumbler I have to clean them pesky pockets.

SOOO MUCH BETTER than vibrating with shell/cobb media! cases come out clean and shiny with clean primer pockets, something Im picky about. Worked good in my rock tumbler so I am going to step up to a full time case tumbler and get another bottle of pins. Just do it!

Finally got around to trying these in my wet tumbler. Theyre just as good as more expensive offerings from your local shop. Recommended if youre trying to put together a loading setup on a budget.

Its really hard to get an idea of just how small these pieces really are. They are smaller than the leftover lead from a mechanical pencil. Thinner than (for a mechanical pencil the smallest i have seen is .05 lead, this is almost .04 diameter) at least they are magnetic but you will need something strong to collect them after a tumble. Id recommend a magnetic hook.
