Le Mas Ltd. Blended Metal Technology Ammo vs. ADS Transparent Armor: AFJI Video!
Posted on Sunday, August 31 @ 23:08:15 PDT by davidc

Ammunition by David Crane

For the last couple of years, Le Mas Ltd. has been pitting their "Blended Metal Technology" ammo (made specifically for them by RBCD Performance Plus, Inc.) against American Defense Systems, Inc. (ADS)/A.J. Piscitelli & Associates, Inc.'s "VistaSteel" bullet-resistant glass, which is manufactured for them by Cardinal LG. Both companies have been engaging in this match-up at AFJI's (Armed Forces Journal International) annual small arms "Shoot-Out". This annual competition has apparently led to constant product improvements on both sides that keep both companies on the cutting edge of their respective technologies.

A couple of weeks ago, I spoke with Stan Bulmer of LeMas Ltd., several times, and came away from those conversations extremely impressed. DefRev is always interested in technologically advanced ammunition that can penetrate either body armor or hard armor targets, and still get the job done on the other side of the barrier. As the reader may or may not be aware, many criminals and criminal organizations are now...

taking advantage of the latest body armor and vehicle hard armor technologies. That's why it behooves both law enforcement (LE) and civilian CCW's (i.e. private citizens with concealed carry licenses) to acquire this kind of ammunition if they can. It doesn't do a police officer or law abiding citizen with a CCW (concealed carry permit) any good to carry a pistol or keep an emergency "homeland security" rifle in their car if they can't effectively use that pistol or rifle to shoot through the badguy's body armor or vehicle windows and doors.

Basically, police and CCW civilians need pistol ammo that will defeat the latest bullet-resistant vests/body armor and deploy properly in soft tissue. They also need rifle ammo that will penetrate the latest vehicle hard armor protection technologies and effectively deploy inside the target sitting inside. I see both police officers and citizen CCW's as having an equal need for this special purpose ammo, post 9/11. We're living in a different time now, and we need both police AND CCW civilians to be equipped with the latest weapon and ammunition technology, so they can effectively engage immediate and dangerous threats IMMEDIATELY, i.e. AS SOON AS they arise. The police simply cannot handle this task by themselves as, most of the time, they will not be there when the violence starts, or in time to positively affect the outcome before innocent people are severely injured or killed. That's why it's up to licensed CCW civilians to help law enforcement officers with this task.

DefRev would very much like to test the Le Mas/RBCD 9mm LE-H SPLP (Special Purpose Limited Penetration) BMT rounds. We would also like to test both the .45 ACP and 9x23mm caliber versions of the LE-H SPLP BMT round. We're also anxious to check out (first hand) the LeMas Ltd./RBCD APLP (Armor Piercing Limited Penetration) BMT and HARPP (Hardened ARmor Penetration Priority) ammo. The HARPP ammo is intended for those situations where you need the highest possible degree of hard armor penetration.

LeMas Ltd./RBCD "Blended Metal Technology (BMT)" ammo is currently only available to verified and authorized military and law enforcement personnel for official use. If you are Mil/LE, and would like to learn more about or acquire some of the most advanced special-purpose ammunition currently being made, you can contact Stan Bulmer by phone at 509-951-4968, or via email at VMOMAX@LeMasLTD.com. You can also contact Stan's associate, John Hamilton, by phone at 501-960-5847, or via email at VNE@LeMasLtd.com. If you or organization have specific ammunition performance needs that your current ammunition can't solve, DefRev is confident that the boys at Le Mas can change all that.

If you would like to find out more about, or acquire, the most advanced bullet-resistant glass currently out there, you can contact American Defense Systems, Inc. (ADS)/A.J. Piscitelli & Associates, Inc. by phone at 516-992-5054 or via email at WRECKDVR@OPTONLINE.NET. DefRev has not yet spoken with the folks at American Defense Systems, Inc. (ADS)/A.J. Piscitelli & Associates, but we plan on doing so, soon.

To read more about the LeMas Ltd./RBCD ammo vs. American Defense Systems, Inc. (ADS)/A.J. Piscitelli & Associates, Inc.'s "VistaSteel" bullet-resistant glass technology face-off, DefRev advises you to read AFJI's excellent "Glass Challenge" article. This article is great reading and very informative regarding Le Mas Ltd.'s and ADS' products. DefRev highly recommends this article.

You can read Le Mas Ltd.'s extensive and entertaining rebuttal to Dr. Gary Roberts' report on the LeMas Blended Metal Technology (BMT) ammo, by clicking here. Some of you may recognize Dr. Gary Roberts as "DocGKR" on TacticalForums.com. Gary is a moderator for their "Terminal Effects Forum", and TacticalForums.com's resident "guru" on ammunition and ballistics. LeMas has provided lots of great pics to go along with their rebuttal to Dr. Roberts.

DefRev has received it on HIGH AUTHORITY that the Blended Metal Technology (BMT) SPLP (Special Purpose Limited Penetration) ammo performance on live tissue is FAR different than its observed performance in calibrated 10% ballistic gelatin. Basically, the LeMas/RBCD "Blended Metal Technology (BMT)" SPLP (Special Purpose Limited Penetration) ammunition's performance is simply not comparable between the two mediums (live tissue vs. 10% ballistic gelatin). A primary factor in this regard is the much lower temparature (degrees F) of 10% ballistic gelatin compared to that of living human or animal tissue.

Calibrated 10% ballistic gelatin literally pulls heat away from the Blended Metal Technology (BMT) bullet as the bullet passes through it. This results in the BMT bullet remaining intact, and not going frangible like it would in living tissue. Live/living tissue, with its much higher temparature, has a totally different effect on the Le Mas/RBCD BMT rounds. A living body's heat is the necessary mechanism for the LeMas/RBCD Blended Metal Technology (BMT) SPLP bullet to deploy as it was designed to do.

Your article states:

"Calibrated 10% ballistic gelatin literally pulls heat away from the Blended Metal Technology (BMT) bullet as the bullet passes through it. This results in the BMT bullet remaining intact, and not going frangible like it would in living tissue. Live/living tissue, with its much higher temparature, has a totally different effect on the LeMas/RBCD BMT rounds. A living body's heat is the necessary mechanism for the LeMas/RBCD Blended Metal Technology (BMT) SPLP bullet to deploy as it was designed to do."

Has an valid and verified engineering analysis been performed to identify and quantify the thermal dynamics involved? Have you examined the data?

What is the minimum temperature required to ensure reliable and consistent projectile deployment?

Since water produces inertial forces that are nearly identical to inertial forces encountered in soft tissues, and inertial force is the primary mechanism that produces penetration resistance and projectile upset, the claim that "body heat" is necessary to produce BMT projectile deployment should be pretty easy to verify by shooting BMT bullets into water at, say, 100-degrees F. Have you examined data such as this?

Has there been any tests of BMT ammunition in cold, artic-like conditions? What are the effects of cold weather on terminal performance?

I'm reposting Stan Bulmer's response to Shawn Dodson's comments above, so it can be viewed more easily.

Here it is:

"There are many factors which determine the extent to which the BMT bullet designs penetrate various impact mediums as non fragmenting projectile, or dramatically deploying frangible bullet design.

Recorded impacts of BMT military and law enforcement bullet designs into calibrated 10% ballistic gelatin show very little expansion or fragmentation. Yet recorded impacts from the same military and law enforcement bullet designs demonstrate dramatic fragmenting and frangible bullet deployments when penetating live tissue mediums.

Reference to the temperature of a partiuclar impact medium as it would affect whether BMT APLP bullet designs penetrate mediums as FMJ, or frangible bullet designs is signifigant only to the extent that the resulting heat energy transmission rates during penetration increase or decrease the projectile temperature to signifigant levels.

The same bullet which will penetrate hard armor without expansion, but deploy as a dramatic frangible bullet design which will not penetrate beyond 4 sheets of 5/8" firecode drywall demonstrates this same type of heat energy transfer rate phenomena that can be observed
between gelatin impacts and live tissue impacts.

BMT APLP bullet penetrations into freshly killed raw meat when cooled to temperatures which approximate calibrated 10% gelatin show very little expansion or fragmentation, yet when impacting both live and recently killed warm live tissue mediums demonstrate dramatic fragmenting and frangible bullet deployments.

It is the very same type non comparable ballistic gelatin performance which allows for the same BMT APLP bullet design to perform as both a passive armor penetrator and limited penetration frangible munition which provides multi mission capabilities from a single weapon platform.

Stan Bulmer's claims are unsupported speculation.

The "heat energy transmission" is total BS. A bullet penetrating 6-inches into 39-degree ordnance gelatin experiences a "heat energy transmission" that is substantially less than passing your finger through a 300+ degree candle flame without burning yourself.

Bulmer has a history of presenting unsupported speculation as fact. Consultation with a qualified, professional thermodynamist easily discredits Bulmer's claims.

If you want to believe Bulmer's BS, be my guest. However don't expect him to present any hard data, nor expert opinion from a qualified professional. He habitually attempts to discredit those who disagree with his claims as lab nerds who're incapable of understanding the realities of shooting "live tissues."

If you're interested in LeMas ammunition, I suggest you request LeMas to provide a professional, peer reviewed engineering analysis of the claims being made. However don't be surprised if Bulmer tries to shuck and jive you with impressive, but unsupported claims.

how come none of the links in this article are working?

I really don't understand how the difference in temperature will make that much difference, I'm not saying it can't i'm saying I don't understand how, considering all the heating during figing...

"A bullet penetrating 6-inches into 39-degree ordnance gelatin experiences a "heat energy transmission" that is substantially less than passing your finger through a 300+ degree candle flame without burning yourself."

and what about heat from friction, i don't see, a lot of the kenetic energy in the bullet will get teansfered to heat from friction. like i saw pictures from the autopsy of someone who got shot in the head and around the bullet's resting place they pointed out, and it was quite visible, the localised cooking from the heat of the bullet.

what difference does 50 degreesF make if the bullet will heat up to many hundreds because of friction?

you know like

Professor: these reactions typically take place at around 20Mdegrees

Student: is that kelvin or celcius

Professor: what difference does it make?

so someone help me out here i'd like to understand
