Weird 9mm brass

[EZ-E]

I bought some bulk 9mm brass & started to deprime it. I came across 2 pieces that have a thicker wall from the base, up the case about 3/4 & then the wall thins up the last 1/4...almost a way to only seat the bullet so far. I measured the wall thickness with my calipers & the thicker wall down low was .051, the thin walls were .015.
Anyone know why this is?

Interesting. Never seen anything like that.

More brass + less powder = same pressure.

Toss is in the round bin.

Thank you sir. Only found 2 in the 500 or so I've deprimed so far. Now to finish off the 4500 or so I have left.

Aguilla? Seen it before. Being a slut, I just load it up.

Recycle them.

Not worth the effort to make a special load for them.

Less volume means more pressure so your normal load may be too much.

Yep that stuff is crap. Pitch it into the Lake of Fire where it belongs with small primer 45 ACP brass.

Not sure the markings are scratched & my eyes are getting worse, even with 1.5 readers...lol

Maxxtech brass? Comes and goes, just pitch it. I'm convinced it is about manufacturing and bullet setback. The extra brass involved costs more than the powder saved I'd bet.
