Lyman Corn Cob Tumbling Media 4.53kg

Lyman Corn Cob Tumbling Media 4.53kg provides a dry media solution for cleaning and polishing cartridge cases in a vibratory tumbler. The 10 lb pack contains natural processed corncob combined with a polishing agent. As a result, it can clean brass and help produce a bright, polished finish during the same tumbling process.

Lyman identifies part number 7631320 as Large Corncob Plus. The manufacturer lists the product as a 10 lb pack. Lyman also states that its case-cleaning media uses 12/20 grit. Therefore, this media suits reloaders who process brass in batches and want a simple dry cleaning method.

Corncob Media for Brass Cleaning and Polishing

During tumbling, the corncob granules work against dirt, residue and surface tarnish on brass cases. In addition, the polishing agent helps bring the cases to a higher level of shine. This makes the media suitable for routine case cleaning before sizing, priming and loading.

Unlike wet cleaning, dry tumbling does not require a separate water-rinsing or drying stage. Instead, the cases remain in the dry media while the tumbler performs the cleaning and polishing work. For this reason, corncob media remains a practical option for reloaders who prefer a straightforward case-preparation process.

Lyman describes Corncob Plus as natural processed corncob combined with a vibrant polishing agent for polishing cases to a high luster. The manufacturer lists several Corncob Plus sizes, including the 10 lb Large Corncob Plus version. The 7631320 part number therefore provides a useful reference when matching the media to the required pack size.

The media can also form part of a wider case-preparation setup. After cleaning and polishing, reloaders can use suitable tools for trimming, deburring and primer-pocket preparation. The Lyman Case Prep Xpress provides several of these functions in one system. Outdoor Guru also carries the Lyman Turbo 1500 Pro Case Tumbler for vibratory brass cleaning.
