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

This product comes in a large pill bottle so I was confused at first. This is actually good though as it keeps moisture from the pins when not in use. The amount at 2 pounds is not really enough for a large tumbler, but would be appropriate for one the size of the average rock tumbler. Ideally suited for removal of discoloration and heavy build up of dirt and debris from metal objects by the wet tumbling method. Use of a magnet later makes clean up a breeze.

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.

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.

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.

im on my second batch of these not because they wear out but because they work so great i got a larger tumbler and needed more, i have reloaded for years and tried many products to wash and clean my brass and this stainless steel tumbling media with a tiny squirt of soap and lemi shine is the best thing i have every used it works great and never wear out, i love it and swear by it and i know you will too

These are great. They are ferris stainless I think because a magnet will pick them up if I drop a few. They clean brass amazingly well.

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!
