Frankford Arsenal
The Frankford Arsenal corn cob media 7 lbs box is a reloader's workhorse for brass case cleaning and polishing. Tumbling brass before processing is the most practical way to start safe, consistent handloads—it removes the dirt, debris, and oxidation that inevitably accumulate on fired casings. Unclean brass isn't just unsightly; it's a real liability for your equipment and your gun. Embedded grit and grime from uncleaned cases will scratch and damage the internal surfaces of your sizing dies with every pass, shortening their service life and degrading case quality. That same contamination accelerates wear in your firearm's chamber and feeding system. A 7 lb box of quality corn cob media eliminates these problems before they start, protecting your investment in expensive reloading dies and preserving your ammunition components.
Corn cob is the go-to media for wet tumbling or dry tumbling workflows. It's gentle enough to polish brass without over-polishing, durable through many reload cycles, and economical for regular batches. Whether you're prepping once-fired range brass or carefully processed ammunition components, this media cuts prep time and delivers consistent results. For handloaders who understand that brass quality and die longevity depend on a clean start, the Arsenal Cob Media box is a no-brainer addition to your bench.
This 7 lb box is sized for hobbyist and serious reloaders alike—enough to handle several cleaning sessions or to maintain a rotating supply. The corn cob medium is ready to use straight out of the box; simply load it into your tumbler, add brass, and let it work while you focus on other tasks. Cleaner brass means cleaner dies, longer die life, better ammunition, and fewer headaches downrange.
The 7 lb box is a standard size for most popular vibratory and rotary tumblers used in handloading. Check your tumbler's capacity to confirm it will hold this quantity; many mid-size tumblers are designed for 5–10 lb loads.
Corn cob media works in both wet (using tumbler fluid) and dry tumbling setups. The choice depends on your preferred workflow; both methods effectively clean and polish brass with this media type.
Media life depends on how often you tumble and the condition of your brass. With regular use and periodic inspection, a box will support many reload sessions. Over time, media breaks down into finer particles; when cleaning performance drops noticeably, it's time to refresh.
Corn cob media is suitable for cleaning rifle and handgun brass. It polishes without aggressive cutting, making it a safe choice for reused cases you want to preserve for many reloads.
