Odd Looking Rust Patterns On 9mm Cases

[rfwobbly]

I don't remember where I got this magnet....

Ford automatic transmission ?

Just use your magnet you use to handle the pins with. Once you picked them out just dump them into the steel recycle bin.

No, those were brass-plated steel cases my friend. Not every S&B case is that way, which is why you need to check.

I know I have some S&B in my 45 Junk box... inquiring minds want to know...

EDIT: Nope... no steel in my 45's.

The bad part of this is without using a magnet you can't really tell. At the same time older ones are brass. Not all casings are reloader friendly that's for sure.

Trash em.
Ive had some oddball steel cases that are brass in color, and berdan primed make it to stage 1 of my Dillon 550b followed by me yelling some cuss words followed by the name of a country they probably came from

This is one of the reasons I cull my 9mm brass... I don't like mystery meat brass in what is a pretty high pressure cartridge. I only use WIN, FC, RP, and PMC brass in 9mm. I'm even pretty leery about using mix-master brass in .45ACP. I was doing a brass inventory just yesterday, and I went through my '45 ACP JUNK' brass box to see what was in there. In these days of waste not whatnot, I'll probably keep it... but I think I'll wave a magnet over it to see what's really in there, that's a good idea.

I have saved all my stepped brass cases in a container but at the present time without data for them and not wanting to experiment they will sit. Especially since 9MM is so plentiful these days. I now run a strong horseshoe magnet through my range brass before sorting to remove the disguised steel junk. I do save them with my other sreel scrap as it all adds up over the long run. Weight is weight no matter what it is you recycle.

My magnet arrived today. I went through my mixed range brass and found these. Thanks again for the suggestion.

I've also learned that a 300lb magnet isn't as much B.S. as I thought. I stuck it to my safe to test, and it took a bit of thought to get it off.

I just went searching for steel pins, and I also found some magnetic rocks, ***?

Bummer - I just trashed a microwave last week. This should work: https://www.amazon.com/dp/B07FLYSZGY/ref=cm_sw_r_cp_apa_glt_fabc_F1FKFY2TAQRGX65KYV96

Go to Harbor Freight or Northern Tool and buy a cheap welder's magnet

If you use those round covered magnets shown above, they can be a bear to get clean.
I’ve fought this for years using those same cheap covered magnets on rusty steel barges I was repairing as a commercial diver.
Putting them in a ziplock sandwich (not thicker freezer) bag before use really helps clean up of rust chards down inside the magnet!
Good luck

Bit pricy however!

Damn, I love S&B brass and have tons of it, chit, now I need to go check it, sigh.

I use a magnet over all the brass I pick up from the range just in case something has gotten mixed in with my brass, just to be sure.
