Frankford Arsenal Stainless Steel Media Pins for Rotary Tumbling

Our review of the Frankford Arsenal Stainless Steel Media Pins finds them ideal for reloaders who want clean, bright brass without a lot of fuss. These pins are aimed at shooters and hobbyists using rotary tumblers, especially in wet media setups, and the single biggest reason to buy is their ability to reach inside primer pockets and case bodies for a deep, uniform clean while remaining easy to handle thanks to their magnetic nature. The set is sized for smaller batches and replacement of lost pins, making it a practical choice for home reloaders.

Key Features

• Size and quantity: Includes 5 lbs of 1mm x 7mm stainless pins, providing enough media for rotary tumbling smaller batches or topping up existing media.
• Material: Constructed from 304 stainless steel for long service life and resistance to corrosion during wet tumbling cycles.
• Cleaning reach: The small pin dimensions penetrate primer pockets and the inside of case bodies to remove fouling and restore shine.
• Magnetic handling: Pins are magnetic so cleanup and separation from brass are fast when used with a transfer magnet or other magnetic tool.
• Compatibility: Formulated as a convenient amount for the Frankford Arsenal Rotary Tumbler Lite and similar rotary tumblers.

Who It's For

These media pins suit reloaders who run a rotary tumbler and prefer wet media polishing for a high level of cleanliness and shine. Hobbyists cleaning batches of brass, and anyone who needs to reach into primer pockets and case necks, will appreciate the small pin size and magnetic convenience.

Those running very large volume operations or exclusively using vibratory tumble methods may want a different media size or quantity; while durable, the package is targeted toward smaller batches and topping up existing media rather than industrial-scale cleaning.
