Frankford Arsenal Stainless Steel Tumbling Media Pins 5 lb 909191

Description

If you've been fighting dirty primer pockets and dull case walls with corn cob or walnut media, wet tumbling with stainless pins is the upgrade that changes everything. This 5 lb supply of Frankford Arsenal 304 stainless steel pins drops into any rotary tumbler and, paired with a liquid solution, gets brass clean inside and out. The pins measure 1mm x 7mm, which is the sweet spot for working their way into case mouths, flash holes, and primer pockets that dry media simply can't reach.

What the Frankford Arsenal Pins Actually Do

Stainless steel tumbling is a wet process, so there's no grit or dust floating around your reloading bench. The pins tumble through a water and solution bath, scrubbing carbon and tarnish off every surface they touch. The result is brass that comes out looking close to factory new, with primer pockets clean enough to seat fresh primers without any extra prep. Because stainless is non-abrasive, it won't eat into your brass or round over case mouths the way harsher methods can, so your cases stay in rotation longer.

Living With Your Stainless Steel Media Pins

The pins are magnetic, which is the little detail that makes this whole system practical. When it's time to separate pins from brass, a transfer magnet makes short work of stray pins hiding inside cases, so nothing ends up in your sizing die or press. With proper rinsing and drying between sessions, this is a lifetime-use product. Five pounds is the standard charge for most mid to large rotary tumblers, so you've got enough here to run full loads of pistol or rifle brass.

This is the kind of reloading supply you buy once and forget about. It pairs naturally with a rotary tumbler and a magnetic separator, and it earns its keep every time you process a batch of range brass back to looking brand new.
