GLOCK 40 10mm and UNDERWOOD EXTREME PENETRATORS VS BULLETPROOF GLASS

[@AnhTrieu90]

All that force and it still didn't deform. That's one badass bullet.

[@rhubarbpie2027]

Copper is a metal that "work hardens" meaning that as it is swaged, pressed, folded, stretched, extruded, etc, it becomes harder. Maybe the rifling squeezing on the bullet helped it maintain its shape, in addition to copper already being *much* harder and less malleable than lead.

[@trelewis3]

[@billh7860]

Since Lehigh Defense makes their Extreme Penetrators in most sizes of handgun calibers how about comparing all handun calibers to see which of them will go through the bullet-proof glass vs stopped by the glass starting with .380 then 9mm, 357 mag, .44 mag., .45,acp and we saw the 10mm. This is great information for both sides of the glass. My guesses are: no to the .380acp and the .45acp but yes to the 9mm, 357mag., .44mag.

[@JoshuaHedgecock]

+bill h I second that.

[@badlandsmunitionsco]

That would be nice. But these things are like 40 bucks a box of 20.

[@frankgon4]

+bill h I third the motion. The 10mm is similar to .357 magnum. I would like to see if .357 magnum goes through

[@frankgon4]

+Luis Bajo The price of the bullet proof glass makes the $40 seem cheap in comparison

[@christopherhowdle6128]

+Luis Bajo I'm sure if you all "donate" that ammo to 22plinkster, he would be happy to shoot what ever you want :p

[@Claimjumper55]

I have a Glock 20 & 29. I've found that most 'off the shelf' 10mm ammo is loaded fairly close to .40 S&W spec. The 3 that I've been impressed with are HPR, Underwood and DoubleTap. Each of them get about 1250 fps from the G29 and 1300+ from the G20.

[@bcviking9381]

+Darrell McMillan Yea wonder why that is? also Buffalo Bore is loaded proper , HPR is the cheapest real 10mm out there .

[@jerry2847]

+Darrell McMillan i have a glock 29 with a 23 pound recoil spring and guild rod and a 6 in lonewolf barrel and i use the new extreme defender round and it works fine ,i use it in a glaco ankle glove for ccw it is my everyday carry gun

[@texastacticaltrainingcente6549]

Buffalo Bore 180gr big game load is 1,350fps and 705ft/Ilbs

[@rustyshackleford17]

Thats the crappy thing about the 10mm. The "affordable" stuff is horribly underpowered, the good stuff is stupid expensive. 10mm is one of those rounds that should push you into reloading because you save a metric ton of money doing so.

[@__Ryan_]

I had underwoods 180@1350 out of my g20 kkm 4.6". Underwood is hot and more affordable than most

[@stephenmilata9629]

Love it! Please, if you can, can you repeat this test, but have ballistic gel behind the bulletproof glass? I would love to see the penetration that the XP bullet has "left" after going through the "Bullet Proof"glass. I'd love to see just how much power it has left, if any. The ballistic gel behind the glass would give me some indication.

[@paulsimmons5726]

Obviously, a few boxes of that ammo is now on the list of things I really want. I found it unbelievable that the bullet looked like it could be reloaded. Thumbs up for the bullet design and production values.

[@JP-jn2yx]

I can't wait you try out the Underwood in my new G40. Looks like a great option for Grizzly defense.

[@007jjb]

Thank you! I had NO IDEA that was possible, that was like a laser beam. That bullet punched through that glass like paper absolutely amazing. I dont think I would want that bullet but the Extreme Defender is what my eyes are on...Like any tool the penetrator has its place I just dont think I need that tool...but WOW! it really is unstoppable.

[@GunGlutton]

I need this gun! I can't be happy without it!!!

[@dpattersonbusiness]

Can you try two additional follow up test. 1. Since the bullet went through the glass using a Glock 40. Test the same bullet using the Glock 20 and 29 in 10mm as well. This should show if the additional velocity of the longer barrel made all the difference or if and when barrel length was a deciding factor. 2. Also try same brand of bullet in the other Glock MOS guns and their respective relatives. This should give more data to link to the first test as well as provide more supporting data across multiple areas.

[@rustyshackleford17]

I'd be really curious if the g29 would have the same results. The civil defense will defeat IIIA out of a 29.

[@thedtmann]

We already know the G40 is more powerful than the 20 or 29, by mere virtue of the 6" (swut she said).

+HeavyHitter5150 Quite frankly, no. You don't. On top of the fact that I have never ever seen an example of an innocent bystander hit by a bullet that passed completely through a bad guy (not a miss, that's a different scenario), the 10mm is so versatile you can choose loads from 135gr all the way up to 220gr. So with proper bullet selection over penetration is a non-issue, just like every other handgun.

[@TheWoundChannel]

***** That has to do with capacity and follow up shots, not over penetration lol. Go ahead, find one example of someone hitting a bad guy center of mass and the bullet passing all the way through and hurting someone else. I'll be waiting...

[@someonewhocares5033]

I am thinking since the regular 10mm fmj acted like a 9mm fmj, see if a 9mm leheigh penetrator will go through like the 10mm did. Also, since you have a 10mm, get yourself a 9x25 Dillon barrel. Smoking fast round.

Probably not. One of the biggest things to defeat body armor is bullet speed. 10mm moves substantially faster than 9mm

[@Swampytheroot]

Just a question; Didn't you compromise the barrier by hitting it with the Armscor first? I don't know the answer, but it looks like, in the video, it created fractures. At 1:20, when the 1st round hits, the whole pane seems to be damaged all the way across

[@fragmentedmind549]

a lot of the 10mm range ammo and some of the defense ammo are fairly light loads, very comparable to a .40S&W and all for good reasons. Underwood, Buffalo Bore, DT have full power loads that typically blow away any large ammo makers 10mm specs. I a defense or range load a full power 10mm is overkill so they keep the loads light, knowing that any heavy 10mm user is going to use custom loads suited for their needs. the lehigh rounds are pretty wicked, great for when penetration and wc is needed.

interesting that the UW load penetrd with only about half of the power of an AK-47 round. Which is the go-to round for this kind of thing. I think it shows the performance of this bullet design in combination with the cartridge weight/speed and caliber. And that's why the 10mm is admired. The other round was the equivalent of the .40 s&w, which ain't shabby by any means...I'd like to see the stock Lehigh Def round which is 1200fps, fired at the panel.

I'm amazed at how undeformed the bullet is more than anything else. For some reason, Underwood seems to advertise this type of ammo as both "Extreme Penetrating" and "Extreme Defender". I couldn't imagine using something like this as defense ammo, all I can think about is over penetration, but it would be damn fun to shoot.

[@williamkissinger3164]

Over penetration like come on its rare enough that you'll even need it it would be more rare that someone will catch a stray behind the bad guy. Maybe in an apartment wouldn't be my first choice but yea chances are astronomical you'll hit a bad guy and an innocent person at the same time. Most people can't even hit the target they spray and pray them the people that may hit someone else by accident. Definitely more of self defense in the wilderness tho lol
