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

I bought it to use in a rotary tumbler which proved far to noisy when in use. Now I use it in my vibration tumbler, and the results are good, though the media is heavier than the walnut polishing material I personally like. For my purpose, the walnut material is easier to use, but the stainless steel media I think gives a better polish. BTW I de-prime my spent primers before cleaning.

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

Excellent for tumbling, very fast shipping and does a great job on cases. I use about 2 lbs per 30 Magnum size rifle cases and am very pleased with the results

I used this product to clean my fired ammo cases. It cleaned the cases with satisfactory results.

Product as described.

Worked great 3hr tumble in frankford arsenal lite tumbler. Better finish peoduct that 2days in walnut dry vibrator. No comparison upgrade to pins

Use this for cleaning cartridge casings and small parts in conjunction with a tumbler.

The stainless steel medium works fantastic. Cleans the primer pockets and the inside and outside of the shells. Add a little lemon fresh and they look new.

Great for cleaning brass!

I use these for tumbling brass. These are awesome as you can just clean them instead of throwing out corn cob media. They are an expensive initial investment, but if you reload often like I do worth it. These things are very very loud though. The reason I give three stars is I would buy an ultrasonic cleaner if I could do it over with the money. If you dont want to deal with the ultrasonic cleaner, this is definitely a lot easier to use as you just clean the tumbling media and the tumbler and thats it. Not need to worry about vibration rates or dilution ratio of your cleaner. Just throw it in and turn it on. So I think it is great for cleaning brass as it doesnt need to be perfect. If you want perfect, get an ultrasonic cleaner.
