[@marcrhodes3382]

This is one of my favorite vids. The shape of the xtreme defender and the honeybadger for me represent the future of defensive ammo. This design negates the validity of hollow points because they simply fail with just a few layers of cloth, sheetrock, fibers, and these will make it so much more reliable and consistent. The temporary cavitation of the underwood is bigger than a hollow point and longer as well. Dont leave home without them!! Thanks for the great vid!! And for your sacrifices !!!America!!!

[@jacktheaviator4938]

Using these rounds for self defense makes me VERY nervous. We set up 5 pieces of Sheetrock and the 9mm extreme defender punched right through, barely even slowed down. Personally, I'm not gonna carry a round with that type of over penetration. I live in an attached house in an urban area, and I really don't want to inadvertently kill my own kid or one of the neighbors. Same reason that my fallback shotgun is loaded with mini shells.

Five (including myself) have a full frame, and two carry a Compact 45 caliber pistol. It would be great to see a Paul Harrell type "meat test".

[@hoffpbass]

No reason you can't have both rounds alternating in you mag. Cover all situations approach.

[@spencermerritt3891]

Judging by this and several other tests I've seen from these Lehigh rounds it seems that they retain KE extremely well until they hit something wet and/or squishy, at which point the geometry causes the projectile to dump KE at a high (and impressively consistent) rate, resulting in highly consistent penetration and wound cavity.

[@spinnie3stax]

.22 was made to deflect off bones and cause more damage.but my biggiest fear is walking through the woods and someone slinging an arrow and it not going all the way through. even if it did the hole arrows make these days are brutal

[@sammoon2906]

.22 long rifle was made first in 1887, it was not designed to deflect off bone, it was made to shoot squirrels, rabbits, and other small game without making them explode like .44WCF(.44-40), or .45-70 did. It as actually designed to do LESS damage. The only reason it does deflect *sometimes* is simply because it's an unjacketed lead bullet, which is 1. How all bullets were made in the 19th century, 2. Why .22lr is so cheap: rimfire, no bullet jacket, very little powder used.

Am I not too far off in saying that the combination of Lehigh and Underwood is making a downright revolution in carry ammo?

[@kai-vp8mz]

Fast forward to 2022 there not really a gimmick brand at all anymore. Controlled chaos, maximum expansion, and the great xtreme defender/penetrator are all super awesome loads that fit their niches very well.

[@acannon2700]

Yes, they're pretty spectacular. Better bullet than anything else for defense from humans or animals. Penetrator is probably better for larger beasties where that long deep wound and bone destruction can work out. Defender causes more expansion and dumps energy much much faster once it hits flesh, with very little worry of overpenetration and collateral (look up tests or perform them on pig carcass and such)

[@evanf1443]

Replying in March 2023. I agree. The service calibers didn't really need the revolution that much but where it really became a game changer was in the marginal pocket carry calibers; .380acp and .32acp. Even the disdained .32acp in the Underwood Xtreme Defender cartridge consistently satified the FBI penetration standard.

[@mbm2355]

Personally, I am *relieved and encouraged* by Lehigh's decision to pare down the *penetrating* capabilities of this round. I was horrified last year by the number of sporting KZbin channels that referred to the Xtreme Penetrator as a "self defense" round. Channel after channel showing slow-motion replays of the Penetrator round passing through multiple blocks of gel without slowing or dumping energy - these are NOT the properties of a Self Defense round, unless you are well and truly alone. That said, this new Xtreme Defender round has hit a sweet spot, in my opinion. As your field tests have demonstrated, the capability to ignore an initial obstacle and penetrate to a known distance consistently, while causing a large initial wound cavity is damn near ideal. I would hesistate to use this round in my home (where I believe 12ga birdshot or hollow-point .45 excell) but in a public space as a concealed carry load, I can't imagine a better round. The ability to ignore an initial obstacle (storefront glass, auto glass, light building material, vanity/deco construction material) and penetrate to an average depth that represents the width of a single attacker every time is a feature not to be ignored. Well done, Lehigh.

Good stuff, especially if you have the X-D and X-P rounds on you in different mags (like for my carbine) for different operations/needs.

Bullets just leaves a straight hole in pork shoulders indetical to a FMJ round in the same tissue. Ballistics gel tears after it stretches a certain amount, this ammo exploits that. Someone really needs to make a video and show what we found at my brother in laws farm...The Lehigh Xtreme Defense and Pentrators, shot in meat, leave wound paths that are indistinguishable from FMJ / ball ammo. The hollow points left far larger cavities / wound paths in our stack of butchers throw away meat.

[@bigmike9128]

I always Wondered?

[@brianbuchert6382]

testing2741 well usually meat from the butcher is drained of body fluid such as blood I’d bet the extreme defender would create a greater wound channel in something that was alive and not butchered and cut up just a thought to your comments we all know ballistic gel isn’t the best tell tale of damage the bullets flutes rely on pressure from body fluid that’s forced outwards to create a bigger wound channel

[@MrMarrok657]

brian buchert well gel only simulates live muscle tissue. No bone, pop a pork shoulder blade or breast plate and see what happens.

[@brianbuchert6382]

MrMarrok657 I’ve seen tests with that done and it’s a solid bullet it does great plus you can say that about any round like hollow point can lose thier integrity and ball penetrate to far but with this round you get penetration through bones and barriers without over penetrate or losing shape with hollow points

Website says this round is as effective as a 5.56. If true, that would be superior to a standard 10mm.

How so? 45 super is 600 ftpounds of energy, 10mm is the same or maybe 700ftp. 556 is 1700ftp? 45 acp is like 390 or 450 ftp?

[@katmarriot4269]

I'm literally just saying what it says on the website. Also, performance is not soley based on muzzle energy. For the record though, .45 acp has 477-700 Joules of energy typically. 10mm has 600-1,000 Joules.

[@wingxxzero]

Those numbers are not accurate. maybe for +p but 700 is completely out of the range of any 45acp. 45 super could handle that probably.

[@frankgonzalez3822]

bullet weight and velocity provided put this in .357 magnum range.

[@LawlessNate]

It puts it in the watered down 357 magnum range. Full power .357 magnum would have much more energy than this. Full power .357 out of a 4" or so barrel should get a 125 grain bullet going ~1,600 feet per second.

[@exothermal.sprocket]

Energy isn't everything here. The projectile doesn't deform, so everything it has is being directed at the footprint it makes upon impact, driving it through. Which means, less energy lost on barrier objects and higher velocities retained through those objects, to ensure good cavitation will result beyond in fluid-like targets. That's not something typically possible with most expanding nose lead-based projectiles, no matter the total weight-x-velocity energy numbers.

[@chgofirefighter]

Would be nice to compare these grains with shorter barrel length pistols in .45acp calibers such as shorter barrel 1911, S&W Shield .45, etc etc

It's too hard to tell if this ammo is a gimmick. handgun bullets only seem to damage what they physically hit in practical applications. ballistic gel is decieving

[@GC_Rallo]

I'm pretty sure any bullet will only damage what it physically hits, bud. XD I'm just messin with ya, I'm guessing you mean like as far as the temporary cavity and whatnot in gel goes, that damage isn't apparent in living creatures. This isn't exactly accurate, while you may not be able to see the damage caused by the hydrostatic shock with your eyes, it certainly has an effect. It's a similar principle to how an explosion kills you, in many cases it's not the secondary projectiles or burns that kills you, it's the pressure wave disrupting vital organs and causing them to shut down. Kindof like when you get hit really hard in the jaw and get knocked out, you're not getting knocked out from the actual impact on your jawbone, you're getting knocked out because the impact causes your head to move rapidly, which jars your brain and causes it to shut down, albeit for a very brief period.

[@20cameron1]

It’s a gimmick. Just another attempt at a magic bullet. Really discredits a gun dealer that believes this stuff. If you need more power, you don’t change ammo, you change to magnum or 10mm calibers.

[@GC_Rallo]

Whether or not the "scalloped FMJ" design of this ammunition is superior to traditional hollow-points in real world situations remains to be seen, since that data really isn't available, so synthetic mediums such as ballistic gel, synthetic bone, jugs of fluid etc are really all we have to go on. While those mediums might not exactly replicate human tissue, and the performance of the round may not be identical in living tissue and synthetic test mediums, you CAN draw direct comparisons between rounds in the same medium assuming the two tests are done in relatively controlled environments, and so far the evidence is promising. Unless you have some substantial evidence showing that these rounds perform no better than FMJ, I don't think you can really claim they're a gimmick. I get that there are people who will always think any new development in projectile technology is just black magic and snake oil, but one has to pretty much disregard 99% of available evidence to come to that conclusion. That being said, some new rounds sound well on paper, but just don't work out in real life, like the G2 R.I.P rounds, but that doesn't mean ALL new rounds are that way. Obviously shot placement is more important than the shape of the projectile when determining how capable a round is at incapacitating a living target, but the shape of the round DOES play a part, and not an insignificant one. Whether it's worth it to pay more for that increased performance is up to the individual.

[@20cameron1]

Abaddon GC Gimmick: (1) Our technology is so now that “new and improved” is rarely improved or better (2) Lehigh and Underwood are not the first to try “extreme” ammo. Can’t remember the brand of ammo, but it was guaranteed to create a huge wound cavity and was a failure. (3) Veteran police officers use hollow points and tell citizens to use them since they’ve seen the results between fmj and hp

(1) I'm just not sure that is true, are you speaking in generalities or specifically on firearms/ammunition development? Everything from video games, computers, firearms, etc are all progressing at faster paces than ever before. It may seem, with all the improvements we hear about on a daily basis, that it all blends together and doesn't seem like any huge significant breakthroughs are occuring, but that doesn't mean that improvements and breakthroughs aren't happening. The fact that so many things are improved/upgraded so often that nothing seems "huge" anymore is actually a good thing, and just goes to show how quickly technology is being developed. (2) Well the name really isn't the point here, it's just marketing. What I'm discussing is the efficacy of the projectile's design. All recorded tests so far have been pretty positive and have indicated that these rounds are effective, whether they are more effective than traditional bonded hollow-points remains to be seen, but only because there hasn't been enough time to make a definitive claim one way or the other. I also don't agree with the idea of "some other new brand of ammo in the past was bad, so that means any new brand of ammo in the future will be bad", in every field there are always ideas that flop, that doesn't mean people should just pack it up and call it quits on ever making any new improvements, it just means that one idea or those few ideas didn't pan out. I'm all for approaching new and shiny things with skepticism, but that can turn into cynicism very quickly which is not a good thing at all. (3) All that says is hollow points are better than FMJ for incapacitating human targets, which is well known. That doesn't really speak to the efficacy of THIS design. The question here is, "Does the scalloped design of the Defender/Penetrator line of ammunition compare to, or surpass traditional bonded JHP ammunition?" and while the testing thus far has generally shown that yes, they definitely compare, and some even show that they could possibly be better than traditional JHP in certain circumstances, there really isn't enough data available to say one way or the other. That's why I'm saying you can't really claim they're a gimmick and have that claim hold any water.

[@ratlips4363]

As always, nice job. I look forward to using this in my USP 45

[@OrangeAmped]

Excellent video! I carry Federal HST in large part because of your videos. I think testing more obscure rounds is good. You never know when something better might come along, and also these sorts of videos help you understand what to expect from a liability standpoint as someone who carries for self defense.

[@ItsBodin]

wouldn't this be legal for use by the military since it doesn't deform when entering a body?

[@glockthirtyfive7617]

Kristobro98 everything would twchnically be legal in USA... the never signed that hollow point treaty.

[@gunnermcbangbang1056]

Kristobro98 per the Hague convention it specifies ammo not designed or intended to cause imminent death, which the design of these rounds are designed to leave a larger temporary and permanent cavity than standard ball. In fact, one of their big sales points is the wound rivals hollow points. So in order to take it to NATO to be approved I don't think it would pass the trials.

[@lovemym16]

guns and life of freedom that doesn't matter the US never signed the Hague treaty. And we never exactly used all NATO rounds anyway. We still have weapons in inventory in 30-06, .45ACP and .40SW

[@ProGunsZach]

So how is this different from carrying a 9mm? I'm a .45 guy myself, but this is a 9mm weigh bullet traveling at 9mm velocities.

[@georgejohnsmith]

First, some hair splitting: 120 grains at 1320-1350 fps and below 21000 psi are not typical 9mm numbers. You do not get 464-486 ft-lbs muzzle energy out of a 9mm unless it is a +p or +p+ round. You can consider the advantages of that yourself. The really important thing: the Extreme Defender essentially is a SOLID. The 9mm or a conventional .45 ACP JHP bullet really must struggle to achieve good, consistent penetration and good effectivity (=energy transfer) at the same time, and barriers usually compromise the performance seriously. The Extreme Defender complies with stringent specifications much easier, with a relatively low sensitivity to barriers that could occur in everyday situations. As a bonus, it is lead-free. This technology definitely is the future, and if the market is able to tolerate the somewhat higher production cost of these bullets, other manufacturers will catch up with Lehigh soon, offering very similar designs. In close range applications, where external ballistic properties are of no significance, heavier expansive bullets are no match to this technology.

[@M60gunner1971]

George just repeated your query back to you in the strange form of a stupefying answer.

[@Falconguygaming]

Zach Cushing I would think it's because it's a heavier bullet for that design, they have a 9mm version but it's only 90 gr. I'm not sure on velocity.

[@drfroglegs]

Well. There is the .451" hole vs. the .355" hole? Other than that, not much...

[@Subtlenimbus]

George, the round tested in this video is up toward the top of 45 +p performance. Pressure is close to 23,000 psi. Still way below 9mm pressures. These 120 grain 45’s are going almost 300 FPS faster than a 124 grain hst in 9mm, from a 4” barrel, so I don’t understand how Zach thinks they are similar to 9mm performance. They are in 357 sig ballpark, with a much bigger hole.

[@tennesseeron1297]

Great video. I use Underwood +P Extreme Penetrator in my .380 Kimber Micro, and now will consider Underwood Extreme Defender for my CCW 3" 1911. Thanks

[@woolygoat2236]

you guys are awesome and just keep getting better another great video! thanks

[@hitssquad]

Someone should introduce an ammo line called *_Reduced Liability_*.

[@billmoyer3254]

I need windshield penetration for cold Pizza delivery. The guy always jumps in the car and does a burnout on my driveway.

[@secnbc]

😂😂😂

[@henrybittle5234]

That was an excellent video. Thanks. Really well put together

[@stephenhair5501]

You definitely went all out on this video. Great performance in that round and well worth saving ones life in a dire situation. God Bless and thanks for sharing. I carry both 45 ACP and 9MM. I'll be getting some of the Underwood.

[@BricksAndSparrows]

You know, this video makes this ammo look really good, but I'm starting to wonder if this bullet design was driven by it's performance in GEL. You can rip that gel apary with your hands (something you really can't do with flesh,) because gel lacks the elasticity of flesh. Gel is a good tester for pre existing designs, because we can use it for comparison.. However it would be possible to design a bullet that exploits the differences between gel and flesh to represent amazing KZbin performance that might not translate to the street. I think these KZbin gel tests are REALLY selling ammo and it would only make sense for a manufacturer to try and exploit the qualifiers that impress us in gel tests...

[@Brandonx-nb7rv]

James Heyward we need to use real world tests. We should gather up a bunch of child molesters and terrorists and have some real ammo tests

[@20cameron1]

James Heyward Plus ballistic gelatin tests don't include fat and bones. Gel is not a legitimate way of testing bullets.

[@jonahpatton8879]

+All Things Magnum sure it is, it being a consistent medium means you can figure out which bullets have a tendency to penetrate more and expand less or vice versa due to the consistency, an inconsistent test medium with bones and fat would be unpredictable and goes against the scientific method

[@SirSpinalColumn]

Gel isn't a comparison to flesh, it's a way of consistently testing 2 different projectiles in the same medium. You can't even compare the result from one gel test to a different gel test unless it's exactly the same composition and temperature.

[@Brandonx-nb7rv]

I was really interested until I saw it was 35.99 for 20 rounds

[@bigchunk1]

Ouch. Seems the price hits almost as hard as the round.

[@smittywerbenjaegermanjense2350]

Not including shipping!!!!

[@terrywaters6186]

It's not range ammo. If you have to shoot someone in self defense do you really care if it's$2 a round instead of $1?

[@jellie33414]

Terry Waters id just use hollow points since these penetrate too good. Keywords: too good

[@crominion6045]

No, it isn't range ammo, but you want to shoot a lot of whatever ammo you're going to carry through your gun, to make sure it performs reliably. You should also practice regularly with your carry ammo. The price of this stuff makes that unrealistic for many people. You're better off finding a lower cost but still reliable hollow point round, like Winchester "white box" 230gr. JHP, which is about the same price for 50 rounds.

[@markhankins3023]

Excellent video, pragmatic and down to earth!

[@Alaskansnakecharmer]

Great video. Thanks Eric. Have a good holiday weekend!

[@caribesd]

2 much penetration = (backdrop damage) x 2 much liability...

[@PeaceManBro]

Eric Al Whats the chance of overpenetrating vs missing your target alltogether.

[@ravissary79]

Eric Al 16 inches is within the 12-18 inch metric created by the FBI. if it's not past 18 inches, then it's not really an over penetrator. And it only dented the back stop, it likely lacks significant force to penetrate a person past that.

[@PeaceManBro]

***** Then you didnt follow the 4 rules of firearm safety, i wouldnt have taken the shot

[@PeaceManBro]

***** And in the heat of the moment i might certainly miss my target alltogether. I never mentioned hollow points, I carry hollowpoints just like most conceal carriers but to me overpenetration is not worth worrying over.

[@terrywaters6186]

Good point Dustin since 80% of all rounds fired in self defense scenarios completely miss the intended target it seems over penetration is the least of our worries.

[@JabariHunt]

120gr @ 1320 fps...so it basically turns a .45 into a 9mm +P.

[@jmayak01]

+Jabari Hunt It sure sounds like it. Just a bigger hole. I'm sorry for saying this, but the Underwood Ammo in .357 Sig with the 125 gr. Gold Dots come in at 1520 fps out of my Glock 32. It will probably penetrate more than these. I guess these would be pretty good at minimizing overpenetration...

[@MrSmith-eg7oh]

A +p 9mm

[@MrSmith-eg7oh]

You're damn right. U think its a good investment?

[@Xtorin_Housecat_Ohern]

okay so whats with this whole high velocity non expanding deep penetrating self defense ammo that i have been seeing, isn't the whole point of self defense ammo to NOT go through the bad guy?

[@ZzBiohazzardzZ]

+Xtorin “Xt” O'hern The point to blow his body in half

[@evanwires4475]

Well done. That is something I would have not considered. This maybe a new definition of a go to round in every aspect. To be continued.....

[@ArtisanTony]

So they trying to make their .45 more like a 9mm :)

[@irhillbillyirhillbilly8605]

no speed kills and if lighter makes speed then it will be like 9mm. so again 45 is better

[@ArtisanTony]

+irhillbilly irhillbilly The typical .45 acp is 230 grn at 900 fps. So yes, they are trying to get closer to the balistics of a 9mm which you will see around 115 grn at 1,300. It's ok, we welcome you .45 acp people to the 9mm family :)

[@stotzmitchell]

+ArtisanTony There's no hope for some people. lol

[@Wanous-hv7zo]

[@gonzalez519]

+Jesse King i understand that it may look like he is doing underwood a favor by promoting this new ammo on his channel but if he and all the youtubers dont show us the new products that are out there who do you think will? I think he is merely pointing out the potential of this new ammo thats all. No beef.

[@chimpaflimp]

Except it isn't a paid advertisement; were it one it would be clearly labelled in the video and description. He's showcasing the ammunition, which is something he has done many times before.

[@RemoteViewr1]

the revern 1. Then use self discipline and avoid curiosity about innovation. Not his fault you indulged, I did too, and I learned a lot. Did you too? 2. Pretty interesting video, again. He simply enjoys this stuff. If it was pure shit, it wouldn't be of interest, I do think even shoot this stuff. My 9mm, hollow point cornbon dpx +p+, 115 grain, scoots along at the same speed, and is just as good at barrier penetration and performance afterwards as this 45 round. Interesting to note. Sorry, what's your bitch? I lost myself. You whining why? Just don't watch, you already know everything.

[@intrepid5592]

Great video guys. as usual. keep it up as lots of my friends really enjoy your presentations...
