cartridge OK to use?

[Mac Cat]

I would be very wary of unknown ammo.
There is a lot of hand-loaded ammo going around, cheap, and it could be bad stuff.
Over loaded or underloaded are both problematic.
I also only shoot FMJ - no lead bullets.

You can hand cycle a few rounds to see how they feed, but my guess is that one on the right is not going to eject easily - the case looks all wrong.

Can we see the printing on the back of the case, too ?

I show the overall length 29.4 mm for my 9mm and 7.65mm.
