2.5 lb Stainless Steel Tumbling Media Pins, 0.039 Inch Diameter, 0.255 Inch Length

Very consistent sizing top quality

Cleaned ammunition brass very well. Make sure to use a pick-up magnet for recovering the pins.

Works fime

Exactly what I ordered. Does a great job wet cleaning ammo. Thank you!

These are tiny and a bit fussy to work with, but they do a great job of cleaning brass in a rotary tumbler.

Metal pins yes metal pins The media is stainless steel pins Small ones as a matter of fact

I used this media to clean brass cases tumbling in a Harbor Freight tumbler. Works great!

Go cheap get cheap. The regular tumbling media was on backorder so I bought this brand. It was about half the price of the one I normally get. It worked fine in my tumbler (reason for two starts), but it did not pick up very well with my magnetic. Wish I have read all the reviews, as there are several other who made this comment.

Throw your dirty brass into a wash solution containing SS pins... turn tumbler ON... an hour later? The brass looks almost new. Inside the cases and the primer pockets are cleaned thoroughly. A word of caution is in order here. Depending on the caliber of the cases being cleaned - specifically the case mouth - you may find one or two pins wedged in the case mouth. Or, a straggler pin could get logged in the flash hole. No big deal. Just push it out with a small punch or something. Simply said. You need to inspect all of your cases before you get to the primer seating step. Running into the issue of wedged pins in 6.5 Grendel case mouth once to often forced me to use the smaller SS pellets which solved the problem completely.

Wow what a time saver. This will clean your brass cases in under an hour or if you give it 1.5 hours it will also clean the primer pockets as well as inside the case. There is nothing that compares and I wish I had have bought one a long time ago!! High, highly recommend getting one. No more cleaning the primer pocket, its now a thing of the past. As for longevity I havent had it that long. But given the design of it, I would expect it to last quite a while. Also like the hexagonal shape over a round tumbler. Seems to agitate the media and brass better. Also, the see through perspex container means I can see how bright they are without having to take the lid off. All in all, I highly recommend it.
