Check your 9mm Luger "brass" with a magnet

[higgins]

I have started finding 9mm Luger cases that are steel, brass plated, and boxer primed; they look like the usual brass cases. They are headstamped KMD and the year (23 on mine). Fortunately they seem to rust quickly when exposed to rain or dew. I found them running a magnet over range brass to pick out the usual steel cases. The only benefit that comes to mind is a source of boxer-primed cases for people who wanted to try to reload steel cases. As long as 9mm brass cases are plentiful and free for the picking up I won't be trying to reload steel.

S&B used to put out brass washed steel cases also.

I run a magnet over all the range brass and range lead I pick up.

Where brass plated steel cases are a problem is when you try to sell them at a scrap yard.

This is one reason I don't reload most foreign 9mm cases. I stick to US brands & PMC seems ok. The others offer all sorts of problems from steel to internal steps to crimped primer & small flash holes & thicker brass causing bulged brass with bullets heavier than 124. 9MM brass is very plentiful at most ranges for the taking so I toss the other stuff.

Thanks for the heads up!

I found another brass-plated steel case headstamp yesterday. FS at 12 0'clock and 9x19 at 6 o'clock. Also boxer primed.

I scrap 9mm brass with the following headstamps: CBC( thick case mouth), military headstamp (sue to crimped primer pockets), GFL, Troy, S&B any any other that is unknown to me.
I limit my loading to Winchester, R-P, Blazer,Speer and Federal. I have no problems with these.

I need to get a magnet, that's for certain.

One other problem with copper washed steel cases is if you use lemishine or citric acid and have one or some in the mix. The citric acid reacts with the steel and will turn nice bright brass pinkish in color. I don't think it harms the brass in any way but discolors the brass. Big Boomer

9mm cases are extremely common. After awhile you'll have collected so many RP and Win cases that you don't need to bother with the others.

I found some SIG 9 mm brass washed steel cases after my last range trip.

I just came across a few x-treme brass colored steel cases. Besides not reloading steel cases the only brass I will NOT try to reload is CDC, which as stated already has very thick walls that prevent a loaded cast bullet from plunking'. My eyes, are just too old n weak to try sorting them tiny headstamps.

I use a harbor freight magnet on a stick to find steel cases in the brass pile. Was surprised to start finding these “brass/steel” cases. I also notice the guys at the scrap yard running a magnet over the bucket too.

I run a magnet over all my brass. Started finding brass washed steel 9mm cases about three years ago. I've also found many 5.56 cases.
