Premium stainless steel media pins for rotary case tumblers. Precision-sized pins clean primer pockets and case interiors that other media can't reach. Rust-resistant, 5-pound box.
Rotary case tumbling represents a significant advancement in ammunition preparation. Unlike corn cob or walnut shell media, stainless steel pins penetrate areas that vibratory methods simply cannot access—particularly primer pockets and case interiors.
Lyman stainless steel media pins are manufactured to precise dimensions that maximize cleaning effectiveness. The correct length and diameter are critical to achieving superior results.
Rotary tumbling with quality stainless steel media delivers cleaner cases in less time. The pins' ability to reach into primer pockets and case mouths produces results that traditional vibratory methods cannot match. For serious reloaders who demand clean, properly prepared brass, this media is an essential component of the reloading process.
