Walnut hull media is the go-to for reloaders who want brass that comes out of the tumbler genuinely clean, not just lightly dusted. Frankford Arsenal's version uses crushed walnut shell that carries a bit more bite than corn cob, so it chews through range grime, dirt, and carbon residue quicker. The nice part is this is the treated version, which means it ships already mixed with Frankford Arsenal brass polish. You load up your vibratory tumbler, drop in your brass, and let it run. No measuring out polish, no guesswork.
Keeping your brass clean is about more than looks. Grit and grime that cling to dirty cases can get pressed into the inner surfaces of your sizing dies and scratch every case that follows. That same debris wears on the chamber and feeding surfaces of your firearm over time. A couple hours in the tumbler knocks all that down before the brass ever touches your dies, which is cheap insurance for gear that costs a lot more than a tub of media.
Walnut runs harder and less porous than corn cob, so it's the better choice when you've got brass that's been sitting in the dirt or picked up at a busy range. Most of the cleaning happens in the first couple hours, and a lot of reloaders get their cases looking close to new in that window. Walnut also holds up well. It's common to get somewhere around 15 to 20 batches out of a charge before it slows down, and when it does, you can refresh it by swapping out part of the old media and adding fresh polish rather than tossing the whole lot.
This 5 lb load comes in a sturdy plastic tub you'll actually keep around. It's handy for storing media between sessions, mixing in polish, or holding your refreshed batch. If you run a two-tumbler setup, walnut is a solid first-stage cleaner that keeps your finishing media cleaner and lasting longer down the line.
Yes. This version ships pre-mixed with Frankford Arsenal brass polish, so there's nothing extra to add before your first run. Just load your tumbler with the media and brass and let it go. Many reloaders add a fresh shot of polish once the media has been through several batches to bring the shine back.
Walnut is harder and a little rougher, which makes it the better cleaner for knocking down dirt, grit, and carbon. Corn cob is softer and tends to leave a brighter polish. Plenty of reloaders run a two-stage process, cleaning first in walnut and then finishing in corn cob, which also helps the finishing media stay clean longer.
That depends on how dirty your brass is and how long you tumble, but walnut typically holds up well and commonly runs around 15 to 20 batches before it needs refreshing. When cleaning starts taking noticeably longer, swap out part of the old media for fresh and add polish rather than replacing the whole batch.
It's designed for dry media tumbling in vibratory case tumblers, which is where it shines. Rotary tumblers are generally run as a wet process with stainless steel pins and water, so dry walnut isn't the intended setup for those. For standard dry tumbling, this walnut media is right at home.
