Check your Fiocchi

[Davehb]

Edit: CZ 75B 9mm.
Fiocchi 9mm 124gr JHP.
That little shiny circle is where it’s hitting the rifling before the slide even fully seats. Polished it dropped in and spun it.
Almost had a boo-boo.
Shot about 10. Standard load 124gr.
Thought they sounded a little harsh. Was ejecting casings twice as far as a Hornady +P. Had failure of slide to close. Slide Wouldn’t seat it. Hard pulling slide back to get it to eject. Felt like it had jammed and hung on a bur.

Thought had somehow got grit in the bore. Field stripped cleaned. 3 times. Got a light checked for burs. Some would seat but still sticking. Just cycling shells without firing When pulling back slide to rack another shell. Felt like it was hung up.
Finally decided to try it in chamber of another gun. Same thing. When side would close hard to get it moving to eject the round. All other brands cycle fine.

First time I tried those. Won’t ever again. Now to see if I can return those 3 boxes.

Great catch !! Very glad you weren't hurt.

Can you report the handgun this incident occurred in, please.

I’m glad it didn’t go really south too. Kind of scary when I realized what was going on.
Cz 75B after it finally crossed my mind might be the ammo tried cycling without firing in S&W M&P9 ez and same thing.
Even When they would fully chamber Try to pull slide back it’d feel like slide was locked up then suddenly turn loose.

Hornady 124gr on left. Fiocchi 124gr middle liberty 50gr on right  in
The Bottom line is where others neck up to full diameter.
Middle line is where the Fiocchi necks to full diameter.
Top line was a mess up.
Those that did seat in chamber weren’t getting out with my fingers. Had to pry them out.
One in chamber still wasn’t fully In the chamber but was stuck anyway.

Is the Fiocchi 124g a JHP bullet?

I forgot to put it.
Yes it is.

Just for Informational purposes here’s the lot number.
I returned them. I left the one in the barrel so they could get it out themselves and see how bad they were locking up in the chamber.
He said they had sold a bunch and I was first one to bring any back. Guessing others haven’t tried them, or don’t know any better.

Gonna have to check all my Fiocchis now. Got a couple of boxes of Black Mamba and Expansion Monobloc (EMB) ammo here at home. (they sure have some diverse ammo types)

Article I found very informative.

Thanks for this @Wobbly

Or, more proabably, the guns those bullets are being fired in have longer chambers and simply don't have a problem.
