Get match-grade clean brass—inside and out—in a single cycle. The Platinum Series Rotary Tumbler 7L (909544) is a heavy-duty, 7-liter wet tumbler designed for reloaders who demand spotless primer pockets, mirror-bright cases, and efficient turnaround times.

Why Reloaders Choose the Platinum Series Rotary Tumbler 7L
True 7-Liter Capacity: Big drum volume supports bulk batches of mixed pistol and rifle brass—ideal for club prep nights, match season, or keeping a progressive press fed.
Wet Tumbling Power: Pair with stainless steel media pins and a quality cleaning solution to cut carbon fouling, burnish case walls, and deep-clean primer pockets.
Quiet & Durable: A dual-layer drum with a noise-dampening rubber liner keeps operation smooth and quieter than open-air vibratory units.
Set-and-Forget Timer: Integrated control lets you select the run time you need—no babysitting required.
Leak-Resistant Design: Secure end caps, robust seals, and stout hardware help prevent spills during long cycles.
Easy Rinse & Separate: Wide mouth makes it simple to pour off dirty solution, rinse, and separate pins (use a media separator or magnet).
Consistent Results: Rotational agitation and pin burnishing polish necks, interiors, and flash holes, producing brass that feeds and measures more consistently at the press.

How to Use (Quick Start)
Load the Drum: Add sorted brass, stainless pins, warm water, and a measured dose of case-safe cleaning solution. Leave headspace for agitation.
Seal & Set Time: Install the end cap/seal, place the drum on the base, and set the timer for the desired cycle (common runs: 1.5–3 hours depending on soil level).
Rinse & Separate: After the cycle, pour off the dirty solution, refill with clean water, and rinse until clear. Separate pins using a separator or magnet.
Dry the Brass: Air-dry on a towel or use a dehydrator/low-heat oven (~150–170°F / 65–75°C) until completely dry.
Store Media: Rinse pins and let them dry to prevent oxidation; a light dash of rinse aid helps reduce water spots.
Pro Tips for Best Results
Deprime First: Running deprimed brass allows solution and pins to scrub primer pockets and flash holes thoroughly.
Don’t Overfill: Keep drum weight within recommended limits; too much brass or too little water can reduce cleaning efficiency.
Use Hot (Not Boiling) Water: Warmer water boosts detergent action and cuts carbon faster.
Additives Matter: A small amount of citric-acid based solution brightens cases and helps prevent water spots.
Protect Your Finish: Avoid long, overly aggressive cycles that can round case mouths; set the timer and check your results.
Maintenance & Care
Inspect Seals: Check gaskets for wear and debris; clean contact surfaces to maintain a leak-resistant seal.
Rinse the Drum: Residue can build over time; a quick rinse after each session keeps the liner fresh.
Cable & Motor Check: Periodically inspect the power cord and make sure the tumbler spins freely with an even, steady rotation.
Who Is It For?
Competition Shooters & High-Volume Reloaders: Clean large lots between matches with consistent, repeatable results.
Precision Reloaders: Ultra-clean cases improve neck tension uniformity and smoother seating feel.
New Reloaders: Simple timer operation and leak-resistant design make it a beginner-friendly upgrade from vibratory bowls.
Frequently Asked Questions
How much brass can I run at once?
Capacity varies with cartridge size and whether you’re using pins. As a rule of thumb, load the drum to no more than ~2/3 full with water covering the brass; keep within manufacturer weight guidance for optimal tumbling.
Do I need stainless steel pins?
You can wet-tumble without pins for a quick rinse and shine, but pins deliver the deepest clean, especially in primer pockets and case interiors.
Will wet tumbling remove anneal marks or polish off headstamps?
Normal cycles won’t erase headstamps. Aggressive or excessively long cycles may diminish visible anneal coloration—set sensible run times and check results.
Is it safe for nickel-plated brass?
Yes, with case-safe solutions and moderate cycles. Avoid harsh chemicals and always test small batches first.
Can I use it for gun parts?
Many users tumble small metal parts, but always confirm material and finish compatibility with your solution/media. Never tumble assembled firearms or parts with springs that could trap media.
