Lyman Stainless Steel Tumbling Media

The Lyman Stainless Steel Tumbling Media provides stainless steel pins for rotary cleaning of cartridge cases. In particular, the pins can reach areas that dry media such as corn cob and walnut shell cannot clean as effectively, including the inside of cases and primer pockets. As a result, rotary tumbling with stainless steel pins can clean both the outside and inside of brass cases.

Lyman makes these pins to specific dimensions for effective cleaning. Furthermore, the stainless steel construction resists rust and corrosion during storage. Therefore, the media can be stored and reused without the same concern about corrosion that applies to some other metal media.

The media comes in a 5 lb box and works with the Lyman Cyclone Rotary Tumbler as well as other brands of rotary case tumblers. Consequently, it does not require a Lyman tumbler to use the media.

Lyman Stainless Steel Tumbling Media Features

First, the stainless steel pins provide a way to clean cartridge cases with a rotary tumbler. Unlike corn cob or walnut shell media, the pins can enter the inside of cases and reach primer pockets. Therefore, the cleaning process can remove dirt and residue from areas that surface cleaning alone may leave behind.

In addition, Lyman makes the pins to the dimensions needed for rotary case cleaning. This helps the media work through the case during the tumbling cycle while maintaining access to the case interior.

Furthermore, the stainless steel pins resist rust and corrosion. As a result, they are suitable for repeated use and storage when handled correctly. After cleaning, separate the pins from the brass and dry the media and cases before storage.

Rotary Case Cleaning

Before tumbling, place the required amount of stainless steel pins and brass cases into a suitable rotary tumbler. Then, add the cleaning solution and water according to the instructions for the tumbler and cleaning method being used.

During the cycle, the pins move around the cases as the drum rotates. Because the pins can enter the case interior, they can also clean areas around the primer pocket and inside the case. However, the exact cleaning time depends on the condition of the brass, tumbler, load and cleaning method.

After tumbling, separate the brass from the pins. Next, rinse the cases and remove any remaining pins. Finally, dry the brass and inspect the cases before continuing with the next stage of case preparation.

For storage, keep the media dry and free from contamination. In addition, a suitable pin separator or magnet can make separation easier when processing larger quantities.

Product Details

In summary, Lyman Stainless Steel Tumbling Media provides reusable stainless steel pins for rotary cleaning of cartridge cases. Moreover, the pins can reach the inside of cases and primer pockets while resisting rust and corrosion during storage. Therefore, the 5 lb pack provides a practical media option for reloaders using a rotary case tumbler.
