Think twice about Lehigh “Extreme Penetrator
http://www.homedefensegun.net/leigh/
This is a guest post by Andrew Bettsleigh penetrator
Lehigh “Extreme Penetrator” and “Extreme Defender” look like Phillips head screwdriver bits and they have one thing in common with screwdrivers: they screw you good. Unlike most normal tools, though, they don’t work. That’s not to say that Lehigh ammo doesn’t fire or won’t poke holes in things. Of course it does. It just doesn’t do it any better than regular full metal jacket. It just doesn’t do any of the things Lehigh claims it does. It’s not like Lehigh doesn’t know this, either. They have to be aware that their claims about fluid dynamics and faerie magic are completely false. It strains credulity to accept that they actually believe their product does the things that they claim. They had to have tested it and they must know their claims are entirely false. That means they are intentionally screwing you.
The reason they have been able to screw customers so efficiently and to grab such a large market share in a short time lies mainly in their social media marketing strategy. In short, the strategy hinges on sending samples to YouTube testers and gun writers with the explicit understanding that they will say nothing negative. While there has long been an implied understanding between manufacturers and reviewers that the reviews not be too harsh or the free stuff stops coming, Lehigh has gone so far as to explicitly state that they will not send ammunition to reviewers without assurances that the review will be positive. As a result, the YouTube testers and gun writers obediently gush about how super awesome this new gimmick ammo is, despite its cost. Please bear in mind that Lehigh never made the claim that their Extreme Penetrator line offered enhanced wounding until the YouTube reviewers decided it looked super cool in ballistic gel. Now, it is possible that some of them are not intentionally misleading their viewers but are simply mistaken. Interpreting gelatin test results can be a little confusing. At first glance, one might expect that the disturbance seen in a gel block would represent the damage that would be done to tissue. The gel is used to simulate tissue, after all, right?
In reality, properly calibrated 10% ordnance gelatin produces penetration, expansion, fragmentation, and retained weight figures that correlate strongly with those same figures as observed in human soft tissue. That gives us excellent, empirical data to compare various projectiles to each other when tests are performed correctly. Gelatin does not produce “wounds” that are representative of a wound produced in real tissue, though. The biggest difference is that gelatin is not nearly as elastic as real tissue (except brain and liver tissue). When a projectile passes through gelatin or tissue, it pushes some of the material out to the side and the momentum imparted on that tissue causes it to continue outward for some distance. The empty space this creates is called the temporary stretch cavity, or TSC. It is temporary because the tissue stretches, then snaps back into place like a rubber band. At velocities exceeding 2,000 fps, this TSC can expand beyond the elastic limit of the tissue and cause tearing. The Lehigh ammunition doesn’t produce velocities anywhere near that, though. That means that the tears that are seen in the gelatin block do not represent wounding. They are simply an artifact caused by the relative inelasticity of gelatin. It is also worth noting that on closer examination, even the exaggerated “wounding” seen in gelatin isn’t that impressive alongside standard full metal jacket.
When you directly compare Lehigh Extreme Penetrator to FMJ of the same weight, the FMJ actually produces a better wound. While neither has the velocity to wound via TSC, the FMJ has a tendency to turn sideways, or “yaw,” which results in a slightly wider wound channel while the bullet is moving sideways.
Lehigh is not the only company that sells gimmick ammunition and they are not the only company that arranges for biased “reviews” from the gun rags and social media. It has long been known that claims in this industry should be taken with a whole handful of salt. If you are choosing ammunition for defensive use, you are strongly advised to avoid anything that claims any sort of “revolutionary” technology and instead depend on established, well documented performers. There are mountains of independent test results available for Gold Dot, HST, and Ranger T as well as many other dependable defense loads. As always, the equipment you select is nowhere near as important as the time that you spend training. Find a competent, certified instructor and take a course. If you have already done that, apply those skills on the range and then take another course. Training is perishable and the more you sweat in training the less you’ll bleed in a fight.

I'm always wary of anything that has anything even remotely in common with snake oil.

Re: Think twice about Lehigh “Extreme Penetrator
There is a similar bullet being hawked that's made from a polymer and metal. I thought it was that one. It all looks like crap. I do want a box of RIP for the odd ball ammo collection.

I don't know about this particular bullet that Lehigh Defense offers, but I can tell you that I've used their Controlled Fracturing and it delivers.
I use it in my 300 BlackOut bolt action for deer hunting and it delivers. The bullet fragments into four pieces and it does expand at subsonic speeds. I know many folks over on 300blktalk that use Lehigh Defense bullets for hunting applications and all have been very happy.
This company is local in SEPA and they really are a good bunch of guys. I had the pleasure of touring their facility a couple of years ago and they were very good at answering any and all questions that I had for them.

Re: Think twice about Lehigh “Extreme Penetrator
I do not use Lehigh Extreme Penetrator, but I do shoot Underwood Extreme Penetrator. Which I carry when hiking in places where I might meet a bear. I CC with a 2 spare mags.The Underwood round is is a the Lehigh brass and bullet loaded with Underwoods powder. It is 115 grain +P in 9mm. The Lehigh is not +P. I also shoot 115 G FMJ in 9mm and Hornady Self defense. The FMJ does not have the penetration of the Extreme. The best test of the Underwood Extreme I have seen showed the bullet to penetrate 36 inches of ballistic gel, then 4 gallon bottles of water, and then land 68 feet from the last bottle. The FMJ did not come close to that.
The weird bullet nose of the Extreme is made to keep the bullet from tumbling to increase its penetration and to increase cavitation. I carry two magazines on my belt. One has the Hornady and the other has the Extreme. I carry the Extreme because it can penetrate walls, doors, car sheet metal, particle board, and other materials that will cause a hollow point to expand too soon, slow it down, and reduce its effectiveness.
If you shoot .380 watch this video which explains why Lehigh XP might be the best self defense ammo you can use.Last edited by Cyclops; December 28th, 2015 at 06:58 PM.

Re: Think twice about Lehigh “Extreme Penetrator
Maybe Polycase? They're superficially similar, but this article highlights interesting differences: http://www.thetruthaboutguns.com/201...0-acp-and-9mm/
Even though they seem similar, the more I studied them, the more I realized that the Polycase ARX and the Lehigh XP really aren’t all that similar. The Polycase has angled flutes, the Lehigh’s are straight on. The Polycase is a round-nose bullet, the Lehigh is a flat-faced projectile with a sharp meplat. The Polycase is a low-weight, high-velocity bullet, the Lehigh is a heavier, slower load. But the biggest difference to me is the way the damage is done — the Polycase seems engineered to create a big initial cavity and then to start tumbling. The Polycase doesn’t rely on its fluted nose to do the damage, other than in the initial impact — after all, as soon as the bullet starts tumbling, that fluted nose isn’t working anymore to exaggerate the damage through radial dispersion.
The Lehigh, on the other hand, is designed to fly nose-forward the entire time, relying on the flutes in its nose to create a wider damage path than a solid projectile should normally be able to do. They both succeed in creating larger damage paths than conventional solid projectiles, but they get at that destination by different means.

Re: Think twice about Lehigh “Extreme Penetrator
Just watched a video on the test of Lehigh Extreme Penetrator in .380. It suggests that it is the best self defense ammo in .380. Watch it here.

Re: Think twice about Lehigh “Extreme Penetrator
From most of testing I have seen with the extreme perpetrator it does do more damage than most FMJs, especially RN FMJ. I don't carry any Lehigh products but I keep up on all the "new" stuff and go through a lot of the testing of the rounds. I make my own decisions off of what I see and experienced and don't count much on internet bloggers, internet "professionals" opinions and etc. These days it seems every guy that spent any time in the military or as a police officer whom owns a video camera and a computer is an "expert".

Re: Think twice about Lehigh “Extreme Penetrator
Why not the hornady critical duty, instead of the Extreme? It was built to pass the FBI barrier tests? Or do you want more push through than that?
Like the RIP round I guess. Quite frankly, anyone who thinks rounds breaking apart is less lethal then a single hole is not thinking it through :-D"Cives Arma Ferant"
