New Ammunition From Lehigh

Lehigh_Defense_Xtreme_Penetrator_Technolofy_ammo-250

Lehigh Defense is offering a new self-defense round called Xtreme Defense, or XD. The new rounds are being manufactured in 9mm and will soon be followed by .357 SIG, .40 S&W, 10mm, .380 Auto, .45 ACP and .38 SPL. They’re designed to create a larger, more devastating wound cavity while reducing risk of over-penetration.

From Lehigh: “Our XD ammunition has an optimized nose flute, total weight, and velocity to achieve a penetration depth range of 18 inches with a permanent wound cavity (PWC) that is just simply enormous; no other expanding hollow point comes close to achieving anywhere near this diameter and volume. Not only is the PWC over 100% larger than any other expanding bullet, it is near barrier blind, ignoring wallboard, sheet metal, and automotive glass.”

Testing was done using the new XD round by the Military Arms Channel’s Tim, who put the round through its paces and recorded the following video:

    If it is barrier proof I would love to see proof of this. A car windshield, glass window, wooden door and plasterboard would all the good things to shoot through and into ballistics gel to test the claim being made.

    • Smiles

      Check out .22 plinkster and his recent video. He shoots a 10mm extreme penetrator right through bullet proof glass.

      • Smiles

        And it didn’t even deform!

  • Giolli Joker

    MAC uses the Underwood loadings.
    Basically we have Xtreme Penetrator bullets that shed some weight, getting velocity levels more in line with Inceptor ARX similar offerings.

  • bull

    doubles as screwdriver….

    • anomad101

      Metric at that.

  • gunsandrockets

    Aw, no .38 Super or .357 Magnum loads?

  • TechnoTriticale

    Perhaps the key feature, for customers living in areas ruled by dum dums, is that these are not hollowpoints.

    I’ll bet not cheap either. Cash in some copper futures before shopping.

    • PK

      On that line of thinking, the primarily copper projectiles could be interpreted as armor piercing, at least in the USA under current law.

      • Chipsa

        All copper is not armor piercing. Has to be brass to be considered armor piercing. Armor piercing is based on construction, not how much bullet resistant Lexan it can go through.

        • nova3930

          Yep plain copper is not listed in the statute. It has to be brass, bronze, or one of the high strength beryllium copper alloys….

          • PK

            Or, if the jacket (if there’s no core the ATF tech branch has interpreted the entire thing as “jacket) is copper and too heavy…

            “A full jacketed projectile larger than .22 caliber designed and intended for use in a handgun and whose jacket has a weight of more than 25 percent of the total weight of the projectile.”

          • nova3930

            Yeah I know. Tech branch is asinine though, as evidenced by interpretations that ignore the plain meaning of the English language…

  • Sianmink

    Another bonus is it’s 50-state legal, thanks to no hollow point.

    • YS

      Would this be legal for warfare under the Hague Convention?

      • ostiariusalpha

        Under the Hague? Absolutely.

      • anomad101

        Why would I care? I am not in the military anymore. Let me explain something to you, anything that kills you, you are still dead.

        • FightFireJay

          What about over kill? Would I be “more than dead”?

          • anomad101

            Only if you are a fanatic about it.

      • Sianmink

        Hague is fuzzy about the whole matter anyway, and was drafted in response to ‘dumdum’ rifle bullets. We’re not a signatory anyway.

  • Plumbiphilious

    Lehigh .357 Sig would probably penetrate 70″+ of gel, if we extrapolate from their .380 performance.

    • nova3930

      I was thinking the same unless they’ve modified the design and at least on the surface that doesn’t appear to be the case. The .380 loads penetrate like mad…

      • Paladin

        I think MAC mentioned in the video that the flutes on the XD are deeper, which would account for the larger wound cavity and shorter penetration.

  • sam

    Neat. The ‘x’ reminds me of dry cat food.

  • He keeps calling it a “permanent wound cavity”. It’s not. it’s the *temporary* wound cavity.

    • Paladin

      No, it’s permanent wound cavity, bullets produce both. The temporary wound cavity, by virtue of its temporary nature is somewhat more difficult to measure, and is often considered to have little in the way of bearing on terminal ballistic effect.

      • My Understanding is that the permanent wound channel is represented by the direct channel of the bullet path, and the “bubbling” effect in gel represents how far the gel disrupted due to the temporary cavity displacement.

        This is how it is described in Fackler’s work, the Military studies, and FBI Wound Ballistics report.

        Is there a resource or documentation that this is incorrect?

        • Paladin

          Every ballistician I’ve ever seen includes the permanently disrupted gel in the permanent wound cavity, and refers to the initial cavitation effect during impact as the temporary wound cavity.

          • Ah, okay. Then I misunderstood how it was being described. Thank you.

        • Darren Hruska

          Well, when you watch high speed footage, you can study temporary wound cavity. However, that’s what it is, temporary. Not that temporary wound cavity isn’t important, though. With enough force, much of that “temporary” damage can result in increased permanent damage. Also, while ballistic gelatin does provide a very good, consistent ballistic testing media (key word being “consistent,” as for comparison of loadings), it doesn’t represent many other things in the human body that may be more or less resistant to temporary-to-permanent damage than muscle tissue.

          • Yes, that I am well aware of. What I’m discussing specifically is the cavity shown in gel around the actual hole punched by the bullet, which I read in the reports to be the temporary cavity, not the permanent cavity. That was my specific point of confusion, hence my original post, and reply. 🙂

    • anomad101

      Temporary would imply you would get over it.

      • Uh, no. Temporary cavity references the maximum displacement of tissue due to the energy pulse. It’s temporary in nature due to the fact that after the energy dissipates, the tissue relaxes and returns to its normal shape and size, save for the permanent damage done.

        Tissue is elastic. This is why when you get a shot, it doesn’t remain the size of the needle. And why if you shoot someone, there’s very little blood from the entry or exit wound, since it puckers up a bit and closes in on itself.

        • anomad101

          No s**t? No, really, I have seen my share of bullet wounds. No stranger to them. Been awhile tho, around 1965.

          • That’s cool. I may have misunderstood the snark in your reply. 🙂

  • iksnilol

    I would like to see this in 7.62×25 Tokarev. That would be nice to have.

    • anomad101

      I do not buy what I can not spell. Never bought a Yugo tho.

  • USMC03Vet

    If I put XD bullets in my XD is that like dividing by zero?

    • Bob

      Then stick it in the microwave…go back in time.

      • anomad101

        I found putting cans in microwave makes interesting patterns on the wall in front of it.

    • Marcus D.

      More like XD squared.

  • Jeff Heeszel

    I know that TNoutdoors9 was not impressed one bit with these.

  • anomad101

    I got an idea, let’s make stuff that does same job, but looks different, and call it “revolutionary”. Keep it simple stupid. Want a non hollow point? Check out FTX round.

    • FightFireJay

      FTX is still a hollow point, they just put an elastic polymer plug in it. This is actually completely different. Revolutionary? well….

      • maodeedee

        Different isn’t always better. Neither is “New and Improved”. Americans have been conditioned for decades now by advertising to believe that the latest gimmick is some kind of magical technological breakthrough and far superior to existing technology simply because it’s new, completely different, and “Revolutionary”.

      • anomad101

        If the point is plugged, how is it hollow?

  • Marcus D.

    So basically what I am seeing is that Lehigh decreased bullet weight to 90 grains and increased the depth of the flutes to control penetration. but then it also appears that penetration is really not an issue except in ballistics gel for the standard weight bullets. And both outperform the HST, What’s not to like? (yeah, yeah, the price, right? But compared to nearly $30 a box for other premium ammo, it is really not out of line).)

  • Zebra Dun

    Four sided spoon tip bullet.

  • Coolhand77

    can I get it in .30 caliber for the M1 Carbine and 7.62 Tokarev loads?

    • maodeedee

      Yeah, maybe you could if anyone seriously thought that 40 grain 30 caliber bullets were better than 110 or 80 grain ones in those calibers. But if you want some decent controlled expansion ammo, Hornady already makes a 30 M1 Carbine 110 GR FTX Critical Defense® load for the 30M1, but for the 30 Tokerev you have to reload the Hornady 90 grain XTP to a max velocity of 14-1500 fps which is nothing to sneeze at.

  • maodeedee

    The nose profile is a good Idea but trading bullet weight (mass) for velocity is a trade-off where you lose more than you gain. what works good in theory and in blocks of Jello don’t necessarily work best in real life.

  • Will

    It’s clear people on here are getting this round confused with the xtreme penetrator from Lehigh. This is a different bullet. They have an xtreme defender and xtreme penetrator. 22 plinkster used the penetrator in 10mm, NOT the defender. The only video I have found using the defender (which this article is referring to) is MAC.

  • LarryNC

    In my opinion, twenty-one inches is too much penetration. His comment about the round not penetrating the width of the hog is just ridiculous. The should bones in that hog, and the very heavy muscle and two layers of pig leather are a HELL of a lot denser than those found in the human torso.
