Good Shot, Wrong Ammo?

[swatsurgeon]

A case of appropriate shot placement (we don't know...does anyone have this info?) and desired effects not achieved or bad shot placement and expected results. Wonder how many steps he would take if LeMas was used with same shot placement??
Dying 7 hours later means a really poor shot OR the ammo did not perform as GEL demonstrated it would, as if you could corrolate it to living tissue.

CU officer cleared in hospital shooting

Terrance Baughman (Brian Brainerd, The Denver Post)A Boulder district attorney's investigation has found a police officer who shot and killed a man threatening to blow up a Boulder hospital acted properly.

Terrance Ashley Baughman, 32, sealed his fate when he got up from a wheelchair in a vestibule and walked into the lobby of Boulder Community Hospital holding what he said was a bomb.

His attempt to move into the hospital followed a period of four hours in which police tried to talk him into surrendering.

The team's orders: attempt to stop the man by firing non-lethal projectiles at him.

Two officers fired four non-lethal rounds. "Baughman doubled at the waist but did not go to the ground," according to the report.

He moved back into the lobby headed toward three police officers. Two more non lethal rounds exploded from the muzzles of police guns.

University of Colorado police Cpl. Matt DeLaria fired a single .308 caliber slug from his Remington 700 sniper rifle into Baughman.

He returned to vestibule and collapsed. Baughman died seven hours later.

No explosives were found.

DeLaria has returned to work after being placed on administrative leave pending the results of the investigation.

Baughman, who turned over a sheaf of papers containing a rambling anti-government screed to officers before he was shot, arrived at the hospital at about 8:50 a.m. on March 17.

"I need you to pay attention to me clearly. I have a detonator and I'm sitting next to an oxygen tank," he said in a 911 call to Boulder PD communications.

Police found him sitting in a wheelchair facing the interior of the hospital.

"Officers observed Mr. Baughman to be sitting in a wheelchair with a green oxygen tank. He also had a black computer case and was holding a red case ... in his lap. The red case was attached to his hand by some type of cord. He told the officers that he had a bomb," the review said.

"This is a pressure switch connected with wire to the oxygen tank," Baughman screamed. "There's shrapnel, it'll go everywhere. If you mess with me I'll blow it."

Patients and hospital employees were moved to safety and a standoff began.

Baughman had an extensive criminal history including assault, weapon possession, arson, burglary and robbery and had a record in Texas, Nevada, South Carolina, Florida, Oklahoma and Colorado, according to the report.

During the standoff, police consulted a psychiatrist who knew Baughman. They learned that Baughman was a sociopath whose threats should be taken seriously, and that he had stopped taking medication for his mental problems, the report said.

"At about 1 p.m. Baughman's demeanor changed from calm to agitated. On the tape recording Baughman can be heard to state "I can start moving over there and you guys can start shooting me ... if you guys are going to start busting caps you should do it real soon."

Sniper Rifle in CQ? Non lethal force in this scenario? Subject's reactions after being shot seems to indicate a torso shot rather than a head shot. To walk and survive for 7 hours with a head shot does not seem likely, at first blush. This is one for NTOA debrief!

[Smokin Joe]

This is one for NTOA debrief!

I agree, I'll be interested to read the tactical debrief on it. The shot placement goes against all of the accepted practices of dealing with a "man with a bomb" call.

[swatsurgeon]

I'm glad it was not just me wondering about that..... only one shot for instant incapacitation that "prevents" the contaction of enough muscle groups to push the button on his detonator, i.e., brain stem. Even a through and through heart shot gives him 10-15 seconds of voluntary actions.

Ah but of course:rolleyes:

“…when a BMT round strikes soft tissue in a chest cavity, the resulting hydrostatic shock is so severe it destroys brain tissue mass”.

[Peregrino]

Ah but of course:rolleyes:

“…when a BMT round strikes soft tissue in a chest cavity, the resulting hydrostatic shock is so severe it destroys brain tissue mass”.

I'm missing something. BMT???? :confused: Though I do believe a .50 BMG COM in the torso would probably produce results resembling an instant incapacitation shot (though the mechanism might differ :D ). FWIW I don't understand the TTPs used either. Unless it was the only available option (and the threat from any presumed explosive device was minimal), torso shots on a "man with bomb" make no sense.

[The Reaper]

Ah but of course:rolleyes:

“…when a BMT round strikes soft tissue in a chest cavity, the resulting hydrostatic shock is so severe it destroys brain tissue mass”.

Having actually seen the LeMas fired into a couple of dozen live tissue patients, say what you will, but unless you can walk around with everything pretty much shredded in an 8"-12" radius, I think it would shut you down pretty quickly. Not going to try and explain the mechanism.

Agree that the SOP should have been headshot as soon as the green light was given.

Bad Dope dialed in on the gun? Didnt account for the angle? Wind Shear?

As to the ammo any low weight bullet loaded to near proof round energy will give you shredding.

Im guessing bad dope, my 700 is still set on 1K settings from the last match. Could be something similar with the police marksman.

[Smokin Joe]

Or he slapped the shit out of the trigger and pulled his shot.

Angle and wind shear???? You jest right??? 99% of all LEO shots are 100m or less, angle & wind are going to have a near zero effect at those ranges. Even from 200m there would be little effect on a .308 round.

And unless it was a glancing blow, a head shot from a .308 at less than 100 meters would have removed most of his head.

I'd also like to see the after action report.

IMO any individual "threatening" with a bomb should be dealt with immediately and unsympathetically.

What I am trying to state is that if you take a lightweight bullet, 45 grains just for discussion purposes, and put enough powder behind it to make it move 1K more fps than the average military 556 round, your going to have a round that is either nearing, or exceeds what is considered a proof round. You are going to have a horrendous wound, one that is very impressive to the eye. Especially if the shooter has not ever seen the effect of non milspec bullets on living tissue.

Also your going to significantly shorten the life of certain parts of the weapon. Air Force CATAM's using DoD approved Frangible ammo have reported throat errosion gauge failures at as early as 1500-2000rounds on M4's. I am not trying to say your ammo is frangible, just that it shares having a light weight bullet and high velocitys, and that is very hard on M4 barrels.

Since we are having a professional discussion, and no one is taking this personally, I will add this.

I am not a ballistician, but I have stayed in s Holiday Inn Express before, and fired hundreds of thousands of rounds through an assortment of small arms. I have personally fired more than 1,000 rounds of the LeMas. I have never seen any excessive pressure signs in any of the LeMas cases, and I have looked at a lot of them. Do you have documented evidence of excessive pressure, especially if it was tested by a strain gauge at an approved testing lab, or is this anectdotal commentary?

The Short barrel LW round is not designed to be fired from any 1/7 twist barrel longer than 14.5 inches. The design limit for the LW bullet from a 1/7 twist barrel is 3650fps. To fire the LW Short barrel 5.56 ammunition in any 1/7 twist barrel longer than 14.5 inches is contrary to product guidelines Le Mas Ltd. provides to its clients. To pressure test the Short barrel 5.56 LW ammunition in a non ported 1/7 twist barrel longer than 14.5 inches is stupid. To then publish such data is very stupid.

[swatsurgeon]

I will say from a ballistics and chest surgery perspective, it is entirely possible that the .308 round hit only soft tissue and exited the chest cavity both intact and with little loss of kinetic energy. I recently had a .270 round go through a patient that left a nice permanent cavity through anterior (front of chest) intercostal muscle, lung and out posteriorly though intercostal muscle...never hit bone and when I operated for bleeding there was a symmetrical hole in the lung, no bullae (changes to the lung tissue c/w a blast type injury/overpressurization). The damage was underwhelming and the patient did well.
The LeMas rounds we fired into the hog chest cavity: some also did not hit a rib and the previously posted pictures speak for themselves: massive tissue damage both to the lungs and heart. Would not have made it if it took 10 minutes to get in the operating room....would have been dead long before getting to it.

So the moral of the story (without first hand knowledge from the operative surgeon or coroner) is theat the round was 1) poor choice of targets...head would have been a primary with his hand on a "detonator" rather than a chest shot, 2) ammo choice: a round that offers a maximum amount of tissue injury regardless if it hit bone to begin its energy dump, tumbling, fragmentation, etc, like the LeMas round could potentially cause enough physiologic and anatomic injury to incapacitate extremely quickly would have been a good second choice if the head shot was not feasible.

TR,

I have read 2 reports, one from Quantico and another from McDill regarding this ammo. I do not have copies to refrence, nor could I refrence them here on this site.

I suspect that both reports came from the same source and neither involved the use of the right weapon and ammo with the appropriate instrumentation to establish the actual chamber pressure in c.u.p. or p.s.i.

Writing a report is one thing. Writing an accurate one is another matter altogether.

Again, nothing personal, not attacking your integrity here. I am just tired of people repeating the same info from the same single source with little in the way of scientific testing or methodology. Love to see something from an accredited source, like HP White Labs, or even Crane, firing the right ammo in the right weapon under valid test conditions.

Last ones I shot were in the 90 grain range, making 2300-2500 fps from a pistol.

You can easily feel the difference. A mag of them feels almost unloaded.

So what exactly do you need to get HPW to do a test?

From my understanding, and that is mostly with armor, all it takes to get HPW to do a test is money. Companies that want to be able to bid on our body armor contracts pay to have their armor tested/certified, if and when it passes the test they can then submit that cert with their bid.

Companies know this and the cost of the tests, which I understand is a large ammount is just the cost of doing business.

[swatsurgeon]

So of course this all comes back to wound ballistics and the desired results of shooting someone:
1) injuring them so they 'should' survive
2) injuring them so they likely won't survive in the long run (alive to get to trauma center and have us try to save them)
3) incapacitating them so the 'threat' is neutralized (LEO world)
a) instantly/damn close to it; no further potential harm can be done by bad guy to self/LEO/public/etc. within seconds of being shot
b) not instantly...potential harm can still be done; pull trigger a few more times, push detonator button a few times, run around the corner/next room/etc. then collapse and die or be able to be resuscitated/operated on and live to see a court room/jail cell/etc.
4) killing them (military world)

So, shot placement, (rules of engagement), type of ammunition and desired/ordered outcome are all a factor. The combination of these 3 are beyond this response but let it be stated that shot placement and ammo type (caliber, characteristics, etc) are the 2 critical factors and the type of ammo can be a larger factor IF a less than ideal shot placement issue is presented to the shooter.
I have dealt with every part of the human body being shot and if you recall the handgun statistics I have posted in the past, only 62% of head shots end in the death of the person.....38% do not and that is with shot placement being right on, so ammo characteristics do make up for the rest of the potential. I don't have rifle stats......but I have to believe more 'should' be dying but I can not support that with data. If anyone has that data please share........

[Odd Job]

Shot placement cannot be discussed only with reference to the position of the entrance wound as seen exteriorly. It has to be discussed with reference to the z axis of the barrel relative to the 3 anatomical planes of the body part that was hit, also. In short, it is more about the incident trajectory than the placement per se (unless you can specify placement with respect to an internal landmark)

For the target discussed in this thread, I would like to know:

1) The position of the entrance wound.
2) The exterior trajectory (muzzle to entrance wound) relative to the three anatomical planes of the thorax.
3) Whether there was any significant deviation of the bullet from its intended trajectory.

If you have points (1) and (2) in line with whatever protocol you are applying to the current target, and you can say no to point (3) then you can discuss ammunition variables because you have excluded sub-optimal placement.

In a case where (1) and/or (2) above are suboptimal, any consideration of point (3) becomes academic, as does any discussion about possible differences in the outcome of the shoot if different ammunition was used.

As for SS's statistic of 62% of head shots from handguns not being fatal, I haven't tried to calculate that percentage from the cases I have access to, but I agree based on experience that a similar number may be arrived at if I sift through the cases seen in the trauma units in South Africa.

However (and this is a big however), medical staff have a tendency to lump many gunshot wounds of the face in with the gunshot heads proper. They also include superficial and tangential injuries in their statistics. This all comes down to the trajectory again. It is very difficult to arrive at a 'clean' gunshot head statistic. Possibly the best way to get a pure head shot statistic would be to have a sample of gunshot heads that have been CTed, and derive the mortality percentage only from those cases where the inner table of the skull vault has been breached. That will exclude trivial injuries to the head and also composite injuries involving the head, neck and chest, where the head injury is trivial but the neck or chest injury is fatal. Of course the sample will have to include only single shots to the head area.

To give you an example of the difficulty in discussing 'head shots,' I had three interesting cases in my research, all labelled as gunshot heads by the triage team:

1) A penetrating gunshot wound where the skin breach was almost exactly between the eyes. An onlooker might say it was good placement. The projectile was deflected by the frontal bone inferiorly through the face and it lodged in the neck. There was no intracranial damage.

2) A penetrating gunshot wound where the skin breach was in the proximity of the angle of the mandible. There was no intracranial damage, but the projectile smashed facial structures, damaged the oesophagus, the right lung, diaphragm and liver. In the books it is a gunshot head, but the patient's most significant injury was to the chest and liver!

3) A contact rifle injury to the face (.303). Almost the entire face was removed. The patient was fully conscious and could squeeze my hand on command. There was no intracranial injury. The features of this injury were very similar to those of a previous case I have seen where an individual had a device explode in his face.

As for handgun vs rifle I also don't have enough cases to arrive at percentages, but I also suspect that the rifle injuries will be more likely to be fatal (if you consider all ammunition types, not just ball).

[swatsurgeon]

As Odd Job stated, the trajectory really tells the story, not just the external shot placement. It would be a great advancement in the world of wound ballistics if the majority of GSWs could have a 64 slice CT scan with 3-D reconstructions to facilitate trajectory mapping. This is my issue with the FBI ballistics lab. Other scandinavian countries are using information from:
-animal testing (live tisue ballistic hits)
- computer modeling
- autopsy data
- surgical/trauma surgeon records
- scene/gun/officer/witness information
- gel tests
They take all of this information for a type of ammunition and let it tell a story. We are trapped in antiquity with the current FBI lab method of wound ballistic "science", actually, pseudo-science in the world of scientific analysis.

Odd job, we need to change the world of american wound ballistics, up for some fun?? This is the genesis of the LeMas controversy: inadequate testing by the 'authorities' on wound ballistics of this type of ammo. Gel does not equal wound ballistics...it is merely a piece of information and far from the entire scope of information.

Back to the case at hand. Odd job, I'll see if the operative surgeon will share more information with me about the particulars of the case in the operating room.

Like I have posted, the LeMas ammo will cause significant injury adjacent to the primary trajectory (permanent cavity and somewhat of the temporary cavity of other bullet types) and has the 'potential' to cause a more severe injury as compared to other commercially available ammo.

ss:munchin

[Odd Job]

@ SS

I agree on the CT, definitely. It would make trajectory mapping very useful.
In the US you are ideally placed to get the right data: in South Africa I had gunshot numbers but we couldn't CT them all and in the UK they all get CTed but there aren't sufficient numbers. I've only seen about 4 or 5 all the time I have been here.

LeMas: I have to keep away from that topic. I've turned it this way and that way in my mind and each way I try to come at it, there are.....issues..
I hope all you gents will understand (for the sake of peace) if I don't comment at all about LeMas ammunition, its manufacturer, agents, sponsors or other parties with a vested interest.
