1-shot killer
This 5.56mm round has all the stopping power you need — but you can’t use it. Here’s why: By John G. Roos Special to the Times Ben Thomas and three colleagues were driving north out of Baghdad in an SUV on a clear mid-September morning, headed down a dirt road into a rural village, when gunmen in several surrounding buildings opened fire on them. In a brief but intense firefight, Thomas hit one of the attackers with a single shot from his M4 carbine at a distance he estimates was 100 to 110 yards. He hit the man in the buttocks, a wound that typically is not fatal. But this round appeared to kill the assailant instantly. “It entered his butt and completely destroyed everything in the lower left section of his stomach ... everything was torn apart,” Thomas said. Thomas, a security consultant with a private company contracted by the government, recorded the first known enemy kill using a new — and controversial — bullet. The bullet is so controversial that if Thomas, a former SEAL, had been on active duty, he would have been court-martialed for using it. The ammunition is “nonstandard” and hasn’t passed the military’s approval process. “The way I explain what happened to people who weren’t there is … this stuff was like hitting somebody with a miniature explosive round,” he said, even though the ammo does not have an explosive tip. “Nobody believed that this guy died from a butt shot.” The bullet Thomas fired was an armor-piercing, limited-penetration round manufactured by RBCD of San Antonio. A new process APLP ammo is manufactured using a so-called “blended-metal” process, said Stan Bulmer, president of sales and manufacturing for Le Mas Ltd. of Little Rock, Ark. Le Mas is the distributor of RBCD ammo. Various bullet types made by RBCD are designed for different effects, Bulmer said. The frangible APLP ammo will bore through steel and other hard targets but will not pass through a human torso, an eight-inch-thick block of artist’s clay or even several layers of drywall. Instead of passing through a body, it shatters, creating “untreatable wounds.” Le Mas gave Thomas a small number of APLP rounds after he contacted the company. After driving off their attackers, Thomas and his colleagues quickly searched the downed enemy fighter for items of intelligence value. They also took time to examine the wound. “There’s absolutely no comparison, whatever, none,” to other wounds he has seen from 5.56mm ammo, Thomas said in a telephone interview while on home leave in Florida. He said he feels qualified to assess a bullet’s effects, having trained as a special-operations medic and having shot people with various types of ammo, including the standard-issue green tip and the Black Hills Mk 262, favored by spec-ops troops. Thomas was the only member of the four-man group who had RBCD ammo. He said that after the group returned to base, they and other members of his group snatched up the remaining rounds. “They were fighting over it,” he said. “At the end of the day, each of us took five rounds. That’s all we had left.” |

Their's No information on the RBCD site, but apparently it was made for the State Department.
It's a frangible APLP(Armored Piercing Limited Penetration round). No info on the weight/grains. But check out this Sequence shot of the 5.56 APLP flying through a slab of meat at 80 Degrees F. That's some DAMN nasty tissue damage! It also contains info on the Blended Metal Technology. [url]http://www.lemasltd.com/1Shot/FactorFiction.htm[/url] Edited to add:Actually, [url]www.lemasltd.com[/url] is the distributor. They have a few different calibers with no prices, An LEO/Gov't only policy, and an order form? |

I can't really seem to find any info regarding specifications, pictures, internal or external ballistics of the round(specifically 5.56).
Anyone? |

Here's the rest of the story from Army Times:
Last year’s defense budget included $1.05 million for testing blended-metal bullets, Bulmer said. Fourteen months into the 24-month period during which those research and development-testing funds must be spent, the military has not purchased a single bullet from Le Mas. Publicly, at least, military officials say RBCD ammo is no more effective than other types now in use and, under certain conditions, doesn’t even perform as well. Those conclusions are derived from a series of tests conducted a few years ago in which RBCD ammo’s effects were observed in ballistic gelatin, the standard means for testing bullets. Naval Reserve Lt. Cmdr. Gary Roberts, a recognized ballistics expert and member of the International Wound Ballistics Association, conducted the gelatin tests in March 2002. According to his findings, “Claims that RBCD bullet terminal performance can vary depending on target thickness, size or mass were not shown to have merit, as bullet performance remained consistent irrespective of gelatin block size.” Roberts found that in gelatin, a 9mm, 60-grain slug exhibited “tissue damage comparable to that of other nonexpanding 9mm bullets and is less than that of standard 9mm [jacketed hollow point] designs, since the RBCD bullet does not create as much tissue damage due to its smaller recovered diameter.” A .45-caliber bullet “offered average terminal performance in bare and denim-clad gelatin, similar to that noted with the 9mm bullet. ... The RBCD bullets do not appear to be a true frangible design, as significant mass is retained after striking a target.” Not surprisingly, Roberts’ assessment remains a major impediment to getting RBCD ammo into military hands. Considering his standing in the ballistics community, his findings are accepted as gospel by many influential members of the special-operations community. But Bulmer insists that tests in ballistic gelatin fail to demonstrate RBCD ammo’s actual performance because the gelatin is chilled to 36 degrees. Their bullets seem to shatter most effectively only when they strike warmer targets, such as live tissue. Bulmer said tests using live animals clearly would show its effects. Despite his appeals for such testing, and the funds set aside by Congress to conduct new tests, the military refuses. Bulmer said authority to spend the testing funds initially went to U.S. Special Operations Command in Tampa, Fla., which delegated testing responsibility to the Army Special Operations Command at Fort Bragg, N.C. Queries to the command confirmed that it was aware of the testing requirement but had not decided when, or if, the tests will be conducted. Bill Skipper, president and CEO of the American Business Development Group, is a lobbyist representing Le Mas on Capitol Hill. “When I heard of the ballistic characteristics of this ammo, as a retired military officer, I realized it has to stay in the good guys’ hands,” he said, adding that SOCom’s reluctance to test it is “irresponsible.” “This is an issue of national security,” he said. Some supporters of RBCD ammunition suggest SOCom officials may be reluctant to test the ammo because it threatens “in-house” weapons and ammunition programs underway at the command. Special-operations forces long have sought a more potent standard round than the 5.56mm, which lacks the punch needed during the long-distance engagements that frequently occur in Afghanistan and Iraq. In response, SOCom is working with weapons and ammunition manufacturers to develop a new round and new upper receivers for M4 and M16 rifles. The command apparently has narrowed its search to a 6.8-by-43mm round. Indication of industries’ involvement in this effort was seen in October during the annual Association of the U.S. Army exhibition in Washington. If Le Mas’ 5.56mm APLP round delivers the performance SOCom is seeking in the new 6.8mm ammo — and Bulmer insists it does — the rationale and the potentially lucrative contracts for producing a new ammo type and modifying thousands of weapons used by special-operations forces would disappear. Thomas said he isn’t familiar with the reasons that might keep RBCD ammo from getting a realistic test within the military. “The politics, that’s above my pay grade,” he said. “All I really care about is that I have the best-performing weapon, optics, communications, medical equipment, etc. I’m taking Le Mas ammo with me when I return to Iraq, and I’ve already promised lots of this ammo to my buddies who were there that day and to their friends.” When military officials in the United States got wind that Thomas had used the round, he quickly found himself in the midst of an online debate in which an unnamed officer, who mistakenly assumed Thomas was in the service, threatened him with a court martial for using the nonstandard ammo. Although Thomas was impressed by RBCD ammo’s performance, he feels it should not be the standard ammunition issued to all U.S. forces. “The first thing I say when I talk to people about Le Mas’ ammo is, make sure that 22-year-old infantrymen don’t get a hold of this, because if they have an accident ... if they have a negligent discharge, that person is dead. It doesn’t matter how much body armor you have on. “This is purely for putting into bad guys. For general inventory, absolutely not. For special operations, I wouldn’t carry anything else.” A video clip on RBCD ammo that was shot at the annual Armed Forces Journal Shootout at Blackwater is online at www.armedforcesjournal.com/bullets. John G. Roos is editor of Armed Forces Journal. You can read the whole story at Armytimes.com. The paper version has pictures of the round. Just looks like a gray/silver FMJ. Ogive is different that M855 or M193. |

RBCD is very good at getting press. Their product is considerably less good.
My sister went back and forth, along with many others including Dr. Fackler and Dr. Gary Roberts, with Stan Bulmer. In the exchanges I've seen it seems clear that Bulmer doesn't understand ballistics at all. There is also no evidence that the State Department ever used the rounds or ordered them at all. I talked to a DSS officer who is involved with supply and equipment selection about it once and he had no idea what I was talking about. (As opposed to the usual: "No comment.") No attempts to conduct real experiments on the round have been permitted with the exception of the gel tests described, which were a failure for the rounds. Instead they just want to shoot deli meat with it and show videos of the results without any other rounds to compare against. Convenient that the round only does its magic in mediums with a higher temp than gel will exist at for long. RBCD claims they have discovered what amounts to life on Mars. A totally unexplained behavior of ballistic motion and terminal effect and one that seems to defy the laws of physics as we know them. Despite this, they refuse to provide anyone with credentials access to the rounds for testing and have, in fact, removed rounds from labs where they were to be tested, apparently to avoid having them tested. As my sister quipped: "Do the math." |
|
This has been thrown around several times, each with NO proof, whatsoever, that RBCD's ammo does what it claims. Sure, they show video's and photos, but they won't let anybody else test the ammo...at least not since Dr. Roberts shot some and gave it a bad review.

"You know that there M193 out of the early 1 in 14 twist M16 used blow them VC's arms CLEAN off..."
There are no magic bullets, only some decent ones, and they ALL depend on placement. |

Quoted: Forget the butt!!!! Lets get some of this ammo and test it against m193, m855 and Open Tips, so as to be out of doubt. View Quote Apparently Gary Roberts already tested the ammo. If so, it would be interesting to ask him if he did test it at 36 degrees? I'm not sure what this means in totality, but if we want to dismantle this story, piece by piece, we need to start at the beginning. So, first we need to dispute Bulmer's claim of the gelatin being at 36 degrees. I agree with Lumpy, there are no magic bullets, but the advances in bullet design in the last 15 years has been incredible. So why couldn't this bullet work? No offense to Doc Roberts (I respect his work), but he does have a vested interest in other projects and the NIH (Not Invented Here) syndrome is alive and well in Washington/military. The closer you get to the core of a project, the more influence the project has on the decisions of the folks involved...remember NASA?, remember the last shuttle flight? If any of you have been involved in a court case where expert witness's are called, well, both sides have experts and they're 180 degrees apart in their testimonies...remember DNA?, remember OJ? True evaluations of any product are best done by third party evaluators with the proper credentials and no financial, political or future benefits (rank, promotions, etc.) All commercial evaluations, of test marketed products, are tested by end users, in black and white packages,with no manufacturers labels, with the result being 'no bias' in the conclusion. It will be interesting to see this story unfold and to be able to find the truth in this matter. In fact, if it is true, it could give new life to the 5.56 round and may be the death of a number of projects currently in progress. Just some thoughts to ponder.... |

Unless and until this projectile is independently tested the claims are smoke and mirrors. All that's necessary to clear the smoke is for the maker to provide the independent testing data.
I'm unaware of any [i]vested interest[/i] Commander Roberts has in any ammunition, he's a researcher of the first order (as is MacPherson, who really is a rocket scientist). One of the principles of scientific research is that the researchers publish their [i]raw data[/i] or provide samples of their devices for independent verification. It ain't true unless it can be proven by others. -- Chuck |

I wonder who this thomas dude " a consultant with a private company" is and how did he get this secret squirrel ammo and get enough familiarity with it to trust his and his teamates life to it.
I would guess that either he has some connection to le mas or he's one of those idiots that will try anything new in dangerous situations. Either of which would be sufficient to discount his input. another reason to discount him is his assertion that this ammo is too dangerous for the average grunt to use and that it should be reserved for SF. Hey Thomas! better take those grenades away while you're at it they can be pretty dangerous too. Flies are buzzing around this pile. |

The more I think about their claims, the more it stinks. Kind of goes against physics and enters the magic bullet arena.
|

The video footage I saw in the History Channel documentary showed those bullets being shot into chunks of meat, with a very impressive explosion-like effect. Impressive. Right. The second I saw that I said to my wife that it didn't look any different than my "experiments" shooting similar-sized chunks of spoiled meat with 75gr OTM bullets, SS109, or 60 gr V-Max bullets.
Maybe those bullets are the Second Coming, or maybe they are smoke and mirrors. In any event, I hope they use some demonstration other than what you can already do with off-the-shelf ammo. |

Delta6,
In the last several years I have been involved with testing a wide variety of items including 5.56 mm, 6 mm, 6.5 mm, 6.8 mm, 7 mm, 7.62 x 39 mm, 7.62 x 51 mm, 7.62 x 54 mm, 7.62 x 63 mm, .338, .45-70, 12 ga, .380 ACP, .38 Sp, 9mm, 357 Sig, .40 S&W, .44 Mag, .45 ACP, as well as a few others. Many of the items we have tested have been adopted by various agencies and units, others have not. Either way, it does not effect me--I report accurate results and the end-users get to decide what to do with that information. I am not in the employee of any ammunition or firearm's manufacturer, nor will I receive any financial benefits from any organization or agency adopting any particular weapon system or ammunition. Exactly what "vested" interest do I have? |
|
I was thinking smoke and "magic Bullet" as well.
However, it would at least be interesting if someone on the board(independant third party) did aquire some of this APLP and ran some of their own tests versus M193/M855 and other load such as the BH SMK loads. |
|
I've just spent an incredible amount of time that I really don't have reading all the threads about this, including the Lightfighter thread, and I think I'm up to speed. Let me just sum up:
1) APLP ammo doesn't do well in ballistic gelatin... 2)...but that's because ballistic gelatin is too cold for it to do it's stuff... 3)...but ballistic gelatin is the "gold standard" for such testing, so the mainstream scientific community doesn't accept APLP as anything remarkable. Okay so far? 4) Some other type of testing, such as shooting 100-200 pound hogs under controlled conditions with proper necropsy is necessary to determine if APLP is really all it's cracked up to be, but... 5) ...BMT either won't do this kind of testing, won't cooperate with others who want to do it, or won't release the results of said testing, and 6) until some type of controlled, quantifiable, scientific testing is performed, the APLP's effectiveness will be proven by nothing more than anecdotal evidence and destruction of deli meats. Does this sum it up pretty well? |

Ballistic gelatin is, by definition, 90% water, with the remaining 10% being gelatin. Is there anyone who believes that fluid dymanics changes in any significant way between 36-39F and 98F? If that was the case, we'd see the same differences with any other round, and we would know this to be a common phenomenon from thousands of other experiments.
The other problem is that, while Seals, Delta, etc. are experts at USING their guns, we also know that very few have any significant knowledge of terminal ballistics. Several companies are using the current war to push their products, which have failed in testing and have been soundly rejected by the military, via media/public pressure. RBCD and Militech are two excellent examples of this. Both companies are spending far more money and effort on their "back-door advertising" campaigns than they are in developing products that can actually be proven to be superior to the products currently being used. In both cases, representatives from these companies have demonstrated a vast amount of ignorance in the areas where they are trying to sell their products. When you fail to grasp or accept well-known and widely-accepted testing methods because their results are "inconvenient" to the sale of your product, then I could not recommend anything that company makes. And pushing your products on the backs of our fallen soldiers is simply disgusting (more of an issue for Militech than with RBCD, admittedly). -Troy |

I have no experiance shooting Gelatin. I was under the impression that ordnace gelatin was calibrated, stored at a certain temp, and kept in a certain temp range during testing?
Does a Block of gelatin at near freezing offer the same resistance to a bullet as a block of gelatin at say desert temps? Ive noticed that often items I take out of my refrigerator are firmer/stiffer than if left out on the kitchen counter all day. Make me wonder if Ballistic gel has the same traits? |

Quoted: Does a Block of gelatin at near freezing offer the same resistance to a bullet as a block of gelatin at say desert temps? View Quote No, it would melt at desert temps, but note carefully that your body does not. Gelatin is used at the temperature specified because that is the temperature that *gelatin* needs to be to simulate flesh properly, specifically to allow the block to remain intact enough that the damage from the bullet is still discernable after the bullet does the damage. My point is: given that you can reproduce bullet behavior with plain water (though you obviously don't get a record of the bullet's performance like you do with gelatin), why would you believe that the properties of the fluid involved (water) are going to be different to any significant degree between 39F to 98F? We would all understand it if we were changing the temperature enough to change the state of the water from liquid to either solid or gas, but we aren't. Also, it's telling that the company is not allowing [b]independant[/b] testing of their ammo on live animals. Instead, they want you to simply accept what they tell you without seeing it for yourself. Without scientific, reproducable, peer-reviewed results, I'll pass, and so will anyone who understands why this practice is valuable. -Troy |

Completely disregarding the apparent target temperature sensing capability of the rounds in question, the article is misleading regarding results of the shot placement;
The description of the wound results suggests a Pelvis / Thigh joint hit which is second only to a direct Central Nervous System hit in its immediate disabling effect. The Pelvic region provides structural support for the entire body and houses major arteries as well. The pelvic bone mass is ideal for causing bullet fragmentation as well as secondary bone fragmentation into the lower abdomen area – especially at 100 yards. In short – the recipient [i]immediately[/i] stops locomotion and is likely hemorrhaging arterial blood. There is nothing surprising to me in the results of the shot – regardless of the bullet used. |

Quoted: So the only issue is did Doc test the RCBS ammo with the Gel at the right temp or not? Right temp, valid test. Too warm or too cold, invalid test. View Quote Great care is done to keep ALL of the factors consistant. Not only is temperature important, but so is calibrating the gelatin with a BB at a specific velocity to test for penetration depth, to ensure that the gelatin is giving consistant results. Dr. Roberts and all IBWA testers all follow the same protocols to the letter, because they publish their results for peer review*, with the full expectation that people around the world will attempt to duplicate their tests. This is the very basis of the "scientific method." If they were not following the protocols correctly, then the results would be different when others went to duplicate the testing. If this happened very often, a researcher would quickly lose his credibility. The reason Dr. Roberts has the respect that he does is because, in hundreds of tests, his results have been duplicated by other researchers and found to be consistantly accurate. * The results that Doc shares with us are really only the summaries; if you subscribe to the IBWA, you'll get the full data, with all of the charts listing each individual test result. Most folks aren't interested in reading 20-30 pages of that, so we get the "laymen's summary." -Troy |

Okay, so let me get this straight. You can't buy it, they won't let anyone have any for evaluation, but a Former SEAL gets his hands on some to take to Iraq?
Sounds like the Chewbacca defense. It does not make sense. Hey Brou, you're deploying to Iraq, aren't you? |
