Stainless steel pins never wear out and will last a lifetime. These are perfect for use in a wet tumbler for polishing brass, steel, aluminum, or titanium. Most commonly used for brass cartridge cleaning, the .047" diameter prevents the pins from getting stuck side by side in flash holes but they will pass through all flash holes one at a time. Fill your tumbler with pins and brass but be sure to leave space to allow tumbling action. Add clean hot water until the tumbler is nearly full. Cold water will work just fine but hot water cleans faster. Add approximately ½ tablespoon Dawn liquid dish detergent (or comparable brand) per 1 lb of brass. The amount of detergent used is not critical but must be enough to ensure good suds remain at the end of the cycle. Run until clean which is typically between 30 minutes and 2 hours. When first starting out check every 15 minutes to see if additional cleaning is necessary. If you don't see suds after you open your tumbler either you are not using enough soap or the soap is breaking down from running too long. Optional: To achieve the best possible shine add a tablespoon of dishwasher detergent powder per 1 quart of water. The active ingredient is citric acid which dissolves zinc. Remove, rinse, and separate the brass immediately upon stopping the tumbler. As soon as the agitation stops the dirt will start to stick back on the brass so don't leave it sitting idle in dirty water. Shake dry the brass in a colander and then pour them into the center of a large towel laid out flat.

I have been hording my range brass for years, thinking that some day I would reload. All the research I did told me that stainless steel pins wet tumbled with your brass is the way to go. These worked great in my frankford tumbler. They are small enough to get inside the primer pockets and clean them out very nicely. I usually add just a squirt of car wash / wax solution to the tumbler, and then let them tumble all night. When I need more I will definitely order these again. I still need to try adding some lemi-shine to the mix to see if that gives even better results.

Amazing product! I used it in a small Harbor Freight 3 pound rock tumbler and had spectacular results. I used about one pound of pins, a teaspoon of Dawn, and 1/4 teaspoon of Lemishine with 100 .223 range pick up cases. Then I ran it a few hours; the water was BLACK with old carbon. The I flushed the drum and just added plain water and ran it all night (out in the garage to isolate the noise). The water was dark gray but the cases immaculate. Even the inside of the cases shined.Three tips. #1. Get a one gallon bucket, put in some old window screen and then a cheap plastic colander over the screen. Dump the tumbler contents in and rinse with a steady stream of water. The screen catches 99.99+% of the pins. #2. I dried them in the clothes drier rack insert, and they were stone dry in less than an hour. #3. Don't overdo the Lemishine; just a 1/4 teaspoon is plenty. Too much discolors the brass. Fantastic results.

So, I'm not using these for the usual reasons. I don't have a reloading setup right now. I'm actually using these to clean the inside of an Aerogarden reservoir. They're great for what they are, but the shape makes it impossible to clean with a bottle brush.Just a handful of these guys, a little water, and a solid shake, and my Aerovoir looks good as new. Bonus, the bits are just magnetic enough to quickly snap to a fridge magnet for ease of cleanup, but not so strongly that they're difficult to get off back into their container.

Great for wet tumbling decapped brass. Lasts a long time. Stainless steel, easy to pick out with a Frankford magnet.

As stated by previous reviewer, lots of smaller pieces. My guess is these are shear cut wire pieces. The smaller pieces seem to be pieces that were caught in the shear dies as mis-cuts or incomplete cuts. Sorting is time consuming but do-able. I use my wife's Lortone rock tumbler, same recipe as others have mentioned and is listed in product description. Works great, although I do have to run smaller batches. Cleaning 10mm and 40 S&W cases, works very well, 30 minutes is all it takes for these small cases. Recommended.

BC Precision had a great price and fast delivery. I use only 1-1/4lb in my homemade tumbler (see picture).Works great on .223 and 9mm, as well as others I'm sure. My first test was on some seriously scroungy range 223 that had been out in the weather for a long time. When tumbled with these pins and detergent and lemi-shine, cases are clean and shiny, inside, out, and even the primer pockets. In my mind way better than vibratory cleaning, which I find takes at least 12 hours and doesn't get brass anywhere near as shiny.A little more trouble separating the pins from the brass, but one of those pickup magnets makes it easy, and it's WAY faster than vibratory. Just rinse the tumbled brass in a colander, and if you're in a hurry, dry in a food dehydrator at low temp, and you're done. The tumbling stage takes only an hour or two (stop when they're as shiny as you want). I change the water at 1/2 hour, recharge with more detergent and lemi-shine, and let it go for the rest of the time. Then I spread out the pins on a piece of cardboard to dry.

they are stainless steel but even after washing many times they still can leave a residue. i wish this company offered smaller. they dont really burnish, they are too large.

The pins were for a wet tumbler I made that is similar to a well known brand for ammunition reloading, I needed the extra pins as the capacity in my drum called for at least 10 lb of pins as I already had 5 lb this was perfect so that I can clean in excess of 2,000 cases at a time.
