Well it finally happened

[cowtown]

Shooting my PSA uppered AR9 today, standing at 50 yards. I've been exceptionally happy with this setup and have 1500 rounds through it with little trouble.

Today I had a squib/misfire. Heard the hammer click but no ignition. Waited 5 seconds, then pulled back the bolt. The empty case came out, and unfortunately I didn't think to take it with me.

I pulled out the BCG and there it was - a nice shiny 9mm lodged in the barrel near the chamber. Thank God I didn't try to shoot again.

Freedom Munition 9mm reloads. To be fair to FM, I've shot probably 6,000 rounds of their 9mm without issue. But I've been reading the CG stories and I think I'm done with them.

I know, cool story bro

Strange... The same thing happen to me today with my AR-9 using my reloads. Though I had to mortar my rifle to get the case out.

At least you have unburned powder. On Mine I don't see any.

This is disturbing if common. Wonder why it would happen more often in an AR9 than other configurations? Could the heavy bolts common to the AR9 be deforming the cases?

Good catch.

Make sure you tell the mfg, they will likely take care of you, if they don't they are out of their mind. Plus, if they don't know what is happening out on the range with their ammo, they won't know to get rid of the wife's nephew who is running the 9mm machine ...

Knock on wood, I've been fortunate that I've never seen this happen before. Aside from the comments here and elsewhere on the net. I'm curios to see unspent powder in there. How did the bullet disengage without the primer detonating?

I've never reloaded and didn't realize the flakes were unburned powder. Is it possible that the bullet seated into the barrel, and I pulled the casing out manually, meaning the round hadn't been crimped properly? Probably showing my complete lack of knowledge about ammunition here.

There's still the issue of it not firing, though.

Did the primer go off? Other wise the inertia could have pulled the bullet out if it wasn't crimped properly but that's very very unlikely

Could have been contaminated powder too and the primer was just enough to push the bullet out and not ignite the powder

Good thing you stopped and didn't try fire another round!

Real FMJ or a Plated bullet?

[Bill Steele]

The round didn't fire. If the primer is not fully seated, the anvil inside the primer is not up against the cup that the firing pin strikes, so when the pin hits the primer the primer material isn't ignited.

If the round is loaded long (or the throat short), the bullet will jam in the throat when the action cycles and loads the round. The firing pin hits the primer, the primer doesn't go off and when the operator cycles the action, the case is separated from the bullet (just like a bullet puller).

The crimp does hold the bullet in the 9mm case, it is only used to take the belling out of the case after the bullet has been seated. Neck tension (the interference fit of the bullet to the case) is what holds a 9mm bullet in the case. In 9mm crimping of any amount beyond just straightening the case mouth just removes neck tension.

Anyway, the guess has to be a less than fully seated primer on a round that was longer than the throat would tolerate (bullet jammed in the throat).

I don't believe so, but didn't think to save the case.

Thanks for that. This seems to explain exactly what happened.

Good catch. Stay safe.

Corrected it, should have said "does NOT". Darn iPad.
