Ventura 10mm Lehigh Extreme Defense/Penetrator armor test

We shoot Ventura 10mm Lehigh 115gr Extreme Defense and 140 gr Extreme Penetrator ammunition from an EAA Witness with a 4.5″ barrel into Clearballistics ballistic gel to measure velocity, penetration, expansion/fragmentation, and retained weight. Buy it at Ventura Munitions.

    So Andrew, do you finally realize and accept that the bigger flutes of the defender creates extra drag that makes the makes the projectile dump energy faster than traditional fmj and more than makes up for the higher velocity? Or do you insist that the defender still behaves like a fmj, even though no test shows that?

    Sorry for the harsh tone, but I’m happy you seem to finally accept that Lehigh does have something unique instead of a “glorified fmj”.

    • No. I don’t “accept” that. And until there is scientifically rigorous testing by an independent party not paid by Lehigh that supports the assertion that the magical flutes contribute to actual wounding in actual tissue, I will remain skeptical. We are fully aware of the interaction with JHP bullets and tissue as well as with ballistic gel. This isn’t Apple vs Android. There are real consequences in ammunition choices. I will grant that Extreme Defender tends to penetrate adequately. Neither over or under the recommended depth. After shot placement, penetration is the most important factor.

  • Vitor Roma

    Andrew trying to be a smartass by supposing that the bullet labeled Penetrator would penetrate less than the one labeled Defender. I guess Lehigh know their bullets.

    • It penetrates more in tissue or gel, than the Defender because the Penetrator is heavier and has a higher sectional density. But it also has more frontal area and a lower velocity, making it less likely to perforate aramid armor. In this case, both perforated, but if one were to fail, it would have been the Penetrator.

    Now that looks like very good self defence ammo. All that’s needed now is to put 16 of them in a light weight Para perhaps with one of those mini-red dots.

    Wouldn’t a bronze bullet perform even better?

    Can we see a test on Level 4 armor?

    • Bronze, along with Berryllilium Copper, Brass, Steel, and Tungsten, are banned for use in pistol caliber projectiles. The exception being for powdered metal frangible rounds.

        Is it a blacklist, or a whitelist? i.e. can we do, say, depleted uranium?

        • Steve Truffer

          Blacklist. DU is on it.
          Any one or mix of : tungsten, steel, iron, brass, bronze, beryllium copper, or depleted uranium

          • int19h

            Well, damn. I guess we’ll just have to stick to copper-jacketed osmium.

        • DU is also banned name.

          • valorius

            Where on earth would a US civilian even get DU238 to begin with?

          • Military surplus? It was banned in the 80’s, presumably when these things were less regulated.

          • valorius

            If i ever found anyone offering to sell DU238 i would be immediately 100% convinced it was a sting operation.

        • But, yes, it’s a blacklist.

    • Level IV will definitely stop it.

    • valorius

      Bronze pistol caliber bullets are illegal “armor piercing” ammo by US federal law.

    • Stuki Moi

      Man, 16 rounds of 10…..Bronze bullets….. You’re making me feel grossly undergunned with my little .38 LCR out in bear country….

  • hahahahaha The backwards bullet literally sticking out of the armor plate like something from Hollywood was pretty awesome. These are some mean motherhubbard loads; if armored felons are a problem in your area, I’d say these EX-TREME!!! things are a pretty good investment.

    • iksnilol

      Or just use a rifle?

      • If I could fit a rifle down the front of my pants, my wife wouldn’t let me leave the house anyway.

        • iksnilol

          A small one, in a shoulder rig.

  • M1911

    140 gr 10mm? If I wanted to shoot a bullet that light, I would shoot .40 S&W.

    I’ll stick with my 220 gr hard cast from Buffalo Bore.

  • valorius

    I carry Underwoods +P loading of Lehigh defense extreme penetrator in my red trigger Ruger LCP. Very accurate, reliable, and in my own tests, penetrates .5″ polycarbonate “bullet proof” glass that will stop .45 acp and 9mm hard ball rounds.


  • Stuki Moi

    Cool test!

    I much prefer seeing tests like this, of stuff that goes beyond the standard “FBI” protocol.

    Manufacturers of defensive ammo already optimize for the “FBI” tests (in standard barrel lengths), so I tend to take them as a bit of a given. This kind of stuff illustrates how rounds do outside their “comfort zone,” and I find that much more interesting.
