Did anyone else catch the mistake about the 9MM pistol used to kill the lady Marine Officer on NCIS tonight? The killer fired the pistol first with a squib load and the bullet stuck in the barrel. Then he pulled the trigger again, driving the both bullets out of the barrel and into the target, bursting the barrel at the time. If you fire an underpowered round in a semi-auto pistol the bullet will probably stick in the barrel but it will not have enough recoil power to recycle the slide and load another round into the chamber. Therefore you cannot blow up a semi-auto by rapid firing with an underpowered round in the clip. However, you most certainly can blow up a revolver if you rapid fire it and have a squib load in the cylinder. I have always been leary about rapid firing a revolver with reloads in the cylinder.

Another mistake, they had the first bullet strike the woman at a very low velocity and the bullet stopped just under the skin while the second one, that pushed the first one out, went through her and almost exited the body. In reality, in that case, they would both leave the barrel at approximately the same velocity, but less than the normal velocity for that kind of round.

And I just thought of another probable mistake. They had one of the bullets, I am not sure if it was the first or second, very much damaged by impact with the other bullet. The other one was not badly damaged. If this really happened I doubt that the bullets would even touch. The air between would probably compress and blow out the first bullet.

Anyway, I thought this was interesting and wondered if anyone else thought so.

The whole thing about the 9mm rounds was totally ridiculous . . . and the rest of the show didn't do much for me either.

After watching 24 for the past couple nights, NCIS didn't stand a chance . . . but they could certainly have put together a reasonable plot. I was disappointed. :thumbdn:
 
I was wondering where they scratched that one up myself. Maybe they've been reading the Mythbusters forum....
 
For a while I thought the entire point of the episode was to get McGee a girl. Then it ended.

I still like it for it's particular brand of camp. but the writing has flatlined recently.
 
Not an expert in guns, so I can't say about a squibb in a semi-auto pistol behaving that way, ie; not cycling the action on the squibb round...
But I have observed it happening in an AR-15... Buddy of mine was shooting it, I heard an odd sound, as did he. But, he looked at the gun, decided it was in battery (with a round in the chamber as it turned out,) and went to fire it. I hit him in the back to stop him and told him to drop the mag and clear the chamber if there was a round in it. I told him to look down the barrel before doing anything else. He dropped the mag, pulled back on the bolt and extracted a round, checked the chamber and then he found the round lodged half way down the barrel. So, at in the AR-15, a squibb round will cycle the bolt...

As to the rest of the show... I still love watching Ziva "man-handling" the idiots!!! :D

The bold will only cycle if the sqibb gets past the port. Remember the AR-15 is gas operated unlike most of the pistols you are talking about which are blow back or retarded blow back.

I don't know about both bullets exiting at the same speed.
Ever shot a pneumatic BB gun? You can chamber one, and then drop 4 or 5 more down the barrel on top of it. When you shoot it they string out vertically. None travel as fast as a they would individually but they all travel at different speeds.
The squib is alot different because you're either dealing with a collision or compressed air between the rounds rather than having them seated to each other and fired at the same time. But I still would guess that the bullets would travel at different speeds. Probably not so different that one exhibits normal penetration and one barely penetrates at all though.

I agree that a squib wouldn't cycle a pistol though. There wouldn't be enough recoil to make bring the slide back all the way, and chamber pressure is obviously very low if the round won't even exit the barrel.
On an AR15, its gas operated, so as long as the squib makes it past the vent to the gas tube its possible that there will be enough pressure to cycle the action.
 
All I know for sure is that I still hate the SOB's for killing off Kate!!!
 
When DHS ran their handgun trials, one of the tests was that the pistol would have a bullet lodged some distance into the bore, and have another round be fired, with causing catastrophic failure. The intention was to simulate a squib load, and subsequent discharge. In order to be considered for adoption the weapon was required to pass that (and other tests). Obviously, there must have been some real concern that could happen for it to be tested for.

Like I said, I'm not the most knowledgeable person about guns :o ... So, as I recall, the bullet was pretty close to the muzzle...

Anyway, as it is a different operating system than a semi-auto pistol, I can't say if there would have been a different result in the handgun... :confused:

Still, since I can't get channel 13 on my little TV, I can't say if I'd like 24 over NCIC, as I've never seen it! :D So I still like the overall NCIS package...

Especially "Rule #9"!!!! And Ziva's observations of it! :D
 
I have been around two squibs that have cycled the actions on semis.

one was in a beretta, and one was in a sig, the beretta was a forty, the sig a 9, both went (pop) and the shooter fired again, the beretta suffered a bulged barrel, the sig got a very light ring in the barrel but kept shooting for a long time after.

The beretta needed a new barrel.

I certainly can't dispute what you say you have seen. However I will bet that none of my 1911 .45's will cycle.

how did the oil get into the powder in the first place? Isn't military ammo sealed, which would prevent anything from leaking in so long as the oil didn't eat the sealant away.
