I have been using untreated corn cob, just recently tried walnut casing. How long are these good for before they stop working or effectively polishing the brass?? And how long do you usually tumble your brass??
Thanks all!

The book that came with my Dillon said not to polish much more than 1 1/2 hour. I noticed pretty close to same on reloading areas on different blogs.
someone suggested Zilla ground English walnut reptile bedding from Petco, and I haven't turned back since. Run it as is for a clean, add Nu-finish to shine it up.

Slightly off topic, but the stainless steel pins never wear out, and an hour or so of tumbling (with a squirt of Dawn dishwashing liquid and a .45ACP casing full of Lemi-shine plus water) leaves the brass looking like new. Also no dust.
Are you using stainless pins in a vibratory tumbler?
1.5 hours.... Lol. I let them run overnight.

I've heard this over and over, but only in reloading circles - a quick Google search doesn't seem to provide anything on this outside reloading information. I'm curious if anyone has more solid info on this.Brasso has ammonia in it, which weakens the brass. It not a good idea to use it on your cases.

The only reason I ask is because I know certain things have been getting Brasso on them routinely for decades around the fire station without being worse for wear. The fire poles, for instance, get shined at least once a week (every Thursday in a station I was at for several years), but they aren't falling apart. Generally they get the brasso applied, then wiped off, true, but it's not terribly uncommon to apply it and then get called out and be gone for an extended period of time before being able to wipe it off. And as far as I know, no pole has ever been weakened to the point of failure - yes they are obviously thicker than casings, but then again, this has gone of for decades, as I said.
I stopped using Brasso on the advice of pretty much everyone in reloading ever, but I'd love to know why I shouldn't. I've read that the ammonia content (which is what everyone points to) is actually extremely low.

Brass is susceptible to stress corrosion cracking, especially from ammonia or substances containing or releasing ammonia. The problem is sometimes known as season cracking after it was first discovered in brass cartridge cases used for rifle ammunition during the 1920s in the Indian Army. The problem was caused by high residual stresses from cold forming of the cases during manufacture, together with chemical attack from traces of ammonia in the atmosphere.
