The Frankford Arsenal Stainless Steel Media is an essential tool for shooting enthusiasts who perform their own case preparation. These magnetic tumbling pins meticulously clean brass cases to a polished, like-new finish. Their 304 stainless steel construction ensures resistance to wear and longevity, while the dust-free tumbling process provides cleaner operation than traditional corn cob or walnut media. Even the smallest internal case areas aren't overlooked, thanks to the compact pin size. The magnetic properties of the pins allow for quick and easy media separation post-tumbling. Designed to pair seamlessly with the Rotary Tumbler Lite system, these pins offer lifetime-use durability for high-volume reloading sessions.
