What kind of bullet is/was this

You answered your own question. It's a 9mm Luger.

Looks longer than this

I don't really know of any common ~9mm diameter spitzer bullet that would weigh that much, that's around a 355 grain bullet if your weight is accurate. I'd guess a 9.3x64mm Brennekee for that area but the bullet is way too heavy for it.

Even the 9.3×74mmR only weighs 286-grain / 18.5 g .

Could the rust have changed the weight?

Steel AP core from something in the 12.7 to 20mm range.

Rust is formed when oxygen atoms bond to iron atoms

Oxygen is 16 grams per mol and iron is 56 grams per mol... could bump those numbers up a fair bit.

Could OP actually get calipers on it and give a proper diameter check

That's what I was thinking. It looks like an AP steel core rather than a bullet.

Looks like an AP core from a HMG. Which HMG I'm not sure.
Looks an awful lot like fiddycal SLAP.

wow you are a faggot. obviously not a pistol bullet.

The steel core idea sounds right. 23 gram is pretty damn heavy for a bullet. thats nearly 350gr.

It kinda looks like the counterweight out of an old window, to be honest.

Is that a famas?
