Some grades of stainless is magnetic. It has to do with what alloys make up the stainless. After all it is 'steel' that is corrosion resistant.

Depending on the intended usage there will be more or less iron in the mix, making it magnetic.

Got mine for $50 from Buffalo Arms.  If you can get it for $35 locally, i'd jump on that IMHO.

Interesting.........what grades are you referring to?

Forgot to look at the range yesterday. I saw some on ebay about $60 shipped for
5 lbs of the ss pins. I think you need 5 lbs for a 30 lbs tumbler.

Magnetic response is the attraction of steel to a magnet. Austenitic grades are generally not magnetic although a magnetic response can be induced in the low austenitic grades by cold working. High nickel grades like 316 and 310 will remain non-magnetic even with cold working.
All other grades are magnetic.


I.E.

Ferritic Stainless Steels Ferritic stainless steel include grades like 430 and contain only chromium as a major alloying element. The quantity of chromium present ranges from 10.5 to 18%.
They are known for their moderate corrosion resistance and poor fabrication properties. Fabrication properties can be improved by alloy modifications and are satisfactory in grades such as 434 and 444. Ferritic stainless steel cannot be hardened by heat treatment and are always used in the annealed condition.
Ferritic stainless steel are magnetic. They are also not susceptible to stress corrosion cracking. Weldability is acceptable in thin sections but decreases as section thicknesses increase.
 Ferritic Stainless Applications Ferritic stainless steel are typically used in:
·         Vehicle exhausts
·         Fuel lines
·         Cooking utensils
·         Architectural trim
·         Domestic appliances
 Martensitic Stainless Steels High carbon and lower chromium content are the distinguishing features of martensitic stainless steel when compared with ferritic stainless.
Martensitic stainless steel include 410 and 416. Hardened martensitic steels cannot be successfully cold formed. They are magnetic, have moderate corrosion resistance and poor weldability.

I've never heard of 434/444, I'm wondering what they are used for?

We do run across a lot of 304/308/316 SS.

I wonder how they'd work loaded into shotgun shells.

I do believe that the radical and crazy notion that the Founders meant what they said, is gradually soaking through the judicial system.

The flyer at the range is $35 for 5 lbs.

I have seen the results of the SS tumbler myself, all I can say is WOW.

+1 to dat!

I bought some (2500) once fired 223 brass from a source that I have purchased from before without any problems. This time, however, the brass had green corrosion inside and a few (hundred) had stuff stuck to the outside which looked like gum and sand.
 
Long story short, I bought the steel media from Spencer and the Thumler's rotary tumbler and ALL the brass looks factory new. And, now I can see a few cases that show signs of head separation.
 
I am very pleased with my purchase although it does add a few minutes to my case prep. But, reloading has become a hobby for me so I am not concerned with rushing through the process.

Does anyone still have Spencer's number for stainless media?

Not sure as I do not see his flyer at the range anymore and the post is over a year old.  Best to call the number & ask.
