Not sure exactly what this is, squib perhaps?

Hard to tell.
I didn't detect a squib but the audio is crappy. Can't see the round he ejected.
4 things I can think of it could be.

1) Squib.
Mistake, he should have inspected the cartridge that was ejected.


2) long seated bullet (handload) caught in lands.
Mistake: he should have inspected the cartridge that was ejected.

3)excessive headspace.
Mistake: he should have inspected the cartridge that was ejected for light primer strike.

4) general barrel obstruction. Coincidence on first round failure to fire.
Long shot, but hey



And whats with smack'in the jam assist? n00b

[XD45]

with the way he was smacking the back I have a feeling its not the first time he's had issues with it..

[Mity2]

slightly off topic, but I nver did like the idea of forword assist on AR's

I understand that if your gun misfire during life or death situation, I may feel deferent. But if ammo don't chamber right, there is a reason why its not chambering.
By forcing it to chamber, your asking for trouble.
Here is good example:
I found this at some sight while back.
Guy shot those CCI's snakeshot 45ACP out of his 1911. appearently, it fired few round, but then it would not chamber right. He tapped the back of slide, then it returned to battery, but he dicided to check to see whats going on.
this is what he found

Appearently, part of casing separated.


scarely part of it is that ammot DID seat all the way(before reing was removed. u can see that ammo is almost all the way in)

can you imagin what could have happened, if he shot the gun with that ring in it?

So next time AR(or any other gun) don't chamber right, STOP, inspect!!

Correct.
NEVER use the jam assist.

In ref to the bolded part, any quality training will teach the tap-rack for failures. With proper repetition and practice of this technique, following said training, your "life or death" situation you will do as you trained.

Another good reason to ALWAYS wear eye protection!

I did not see them eject the first round, which I believe they should have checked it out. Second they need to be more responsible and trained. the shooter meade a joke about his buddy not being able to load the rifle, when he should know how to load and use the rifle, and should have been shown before being at the range.

[Pa. Patriot]

I did not see them eject the first round, .

Well, he charged a new round, to which you could hear the old round hit the table.

[bloomautomatic]

i agree w/ patriot on the causes. a squib round lodging a bullet in the barrel, followed by a normal round would be my first guess.

always nice to have your f'up caught on video for the world to see.

An experienced shooter would not be buying a new upper...

Here's the sequence:
- round #1 doesn't fire
- cycle the action (chamber round #2)
- round #2 won't chamber cleanly
- slam the forward assist a few times to "make it fit"

Sounds to me like round #1 was a squib load (with no powder).

The primer had enough punch to push the bullet into the barrel, but not 100% clear of the chamber. This caused round #2 to require excessive "assist" in chambering.



I've had squib loads in pistol rounds - no powder at all, and powder that didn't ignite.

The powder measure on my progressive press got stuck. I loaded 6 or so rounds of 9mm before I noticed it. That was the last time I used a flake in that measure. The failure to ignite was some older Wolf 380ACP. The primer went pop, but nothing. When I removed the case, my hand was showered in powder.

In both cases, I knew enough to check the bore. Sure enough, the bullet was stuck in the rifling. Knowing that the barrel was obstructed, I tried to chamber the next round, just to see if it would. In both cases, the slide would not go into battery.
