QUICK NOTE: I learned during the production of this video that the bullet "grain" refers to its mass, and not the grain measurement of the gunpowder. Apologies for misspeaking during the video!
I appreciate the fact you say this. As someone who grew up around firearms and everything, I also assumed that’s what it was too. Learned maybe a year or two ago that it was bullet weight and not powder and went “huh.. I’ve been super wrong my whole life” lol
This is the cleanest and most clear slow motion footage of gel ballistics I’ve ever seen. I’ve scoured the internet and RUclips looking at these videos, to the point where my wife now hates RUclips. This was amazing. I hope to see more of these ballistic tests at this quality. Subscribed and liked, and left a comment for the algorithm gods. Top Notch fellas.
I've seen slower more clearer, but this was pretty good. Another trick I like that they don't tell you about is to rewatch the slowmo parts at 1/4 speed.
Just in case it isn't mentioned elsewhere, the reason for the secondary detonation in the gel is from the collapsing gasses. This is the same thing as a diesel engine combustion. The compression of the bubble collapsing compresses the gasses enough for ignition, and the fuel is either raw powder or the gel itself.
Your channel will grow tremendously if you keep up the quality of your videos like this. Amazing work, would love to see every grain of federal hst 9mm if ever possible.
That certainly looked like the Leheigh projectile that Underwood uses in Xtreme Defender. Military Arms Channel has a great comparison of 90 grain +P vs +P+ No high speed (that was cool) but very in-depth.
Just a heads up less grain weight bullets normally always go faster and incase you was confused the grain weight is the bullet weight not the powder charge
I'm surprised by how quickly the fluted bullet destabilizes; those things are supposed to derive their wounding potential from hydraulically displacing material, not wobbling around and tumbling. Would be interesting to see how the G9 bullet design fairs in the same kind of test. Great job on these videos, this is really cool to see!
@@BallisticHighSpeed you are the most amazing channel on RUclips. I absolutely love you. You truly are the best. In a few years you will reach more than 1 million subscribers
You’ve earned my sub. The footage is the clearest and best slow motion I’ve seen to date. Coupled with the amazing sound effect it’s a pure thrill to watch. 🦅🇺🇸
Your second video, my first viewing ( i don't know why i got no notification) . Loving your show for the last two years. Carry on blowing stuff up and showing it in gloriously slow motion colours 🏴🤔😇🏴
Wow i cant thank you enough for providing this insane quality video for free. Please try the liberty defense 9mm hollow point traveling at 2000 fps vs a 45 acp round. a lot of people think a heavier slow bullet does more damage than a fast light bullet. I believe a fast bullet is more deadly.
@@tihruytssgjjvsavcxtbvhj3429 overpenetration is useless because it means the force of the bullet is not quickly put into the target to wrangle the organs and deal fatal damage. A straight pass through will not do much. also, the bullet can end up in a innocent civilian.
@@RBWVETDOC yeah I have some that both cases are jag but some have gold primers and some regular silver color. The boxes have different I queasy lot numbers. Made different times using what ever components they can get that are good quality. I know they get their bullets from lehigh they kind of partnerd up.
Somehow faster with less grains? That's very normal. With everything else being equal, a lighter projectile will have more velocity. 1,000 horsepower with push a Miata a heck of a lot faster than it will push a 3/4 ton 4 door pick-up. Great video btw. I'm looking forward to seeing your channel grow. Have a sub!
It doesn't. The sounds are added in post processing. There are guys who specialize in creating fake slow-motion sound effects to be added to slow-mo videos. If they used the real sound, it would sound like very loud radio static.
Just throwing this out there for peoples knowledge. The Xtreme Defender bullets used by GH Ammo, Underwood and any others that use them are all made by Lehigh Defense. I believe they are all loaded to Lehigh specifications too. Just letting everyone know so they can check them out and see all the awesome bullets they make.
I like the slo mo, but why the switch up on the guns? Initially firing the extreme through a FDE framed, threaded barrel Glock, then the slo no is of a standard 19.
@@BallisticHighSpeed LOVE the videos brother!! Always a great thing for more brothers and sisters to join the 2A Community and Protection of yourself and loved ones. 🇺🇸🇺🇸
Need to get some good 300 blackout and 5.56 defensive ammo vs torso. But make sure you do not use subsonic ammo for the 300 AAC. As almost all defense ammo in 300 is supersonic at 120 grains or less.
So cool to see how everything acts/reacts in slow mo. I can’t tell if it was just me or if (especially on the ball round) you could see the bullet yawing a little as it exits the muzzle? Also I noticed when you get the dieseling effects in the gel, it’s always when the largest section of the temporary cavity recompresses. I’m gonna end up watching this a few more times now to see if there’s any solid footage of what the bullet is doing to make the wound channel larger in one area compared to another. Because if you noticed the dieseling happened closer to the exit with the ball round (I think about where it began to tumble) and closer to the entrance on the penetrator round (which seemed to possibly start tumbling and doing that lateral rotation closer to the entrance wound). Definitely gonna watch this a few more times to analyse it like a real nerd.
The larger cavities are due to the round beginning to transfer energy as it meets increased resistance; you can see how the shape of the bullet is a major factor in when the energy transfer occurs, especially in handgun calibers with short barrels and relatively low velocities.
The faster the bullet travels, the larger the cavity. That's why 556 is so deadly compared to 9mm. its cuz the high velocity puts so much trauma to ur organs.
It's interesting to me to see the amount of unburnt powder from the handgun. I assume the burn would be more complete in a longer barrel and I'd like to see a video covering that.
If you hand load you’ll notice that all the load data in a lyman book is from testing in a 6” barrel. I’ve always assumed that is what mfr uses to work up loads because it’s better to load for the longest barrel and have un burnt powder in shorter barrels than to have ammo run out of steam halfway through a longer barrel. When I was hand loading I would always have to modify powder charge to fit my specific barrel length
That was fun to watch. So the extreme ammo’s shape, allows the force of the bullet to affect closer to its impact point rather than further away? So, a human torso is shorter than a rectangle of gel; the original fmj looked like its force generated upon impact, affected the furthest end of the gel the most, so when a 9 would hit a person, the most force generated is after it passes through?
Really great video...I think this channel is going to do really well as I don't know of another one like it on youtube...keep it up!! I would love to see hollow point vs FMJ also
And i love your whole idea and a way you make this videos, all short clips not to much talking just right and important !! Love it and don t stop or change the idea. Btw I got one idea for you how to setup lower spread of bullet over balistics gel.
Awesome video fellas‼️ 😳😲😵👍👍👍👍🔥🔥🎯🎯🎯💯💯 I think Lehigh defense or Underwood have the same projectile‼️ I'd like to see a test between the round you showed and the lehighs or underwoods Extreme Penetrator and Is extreme defender
Looks like the Lehigh Defense 9mm, 90 gr +P I have used. Other videos described it as "barrier blind" due to its awesome ability to penetrate barriers and enter the ballistic gel.
So was that "explosion" caused by sonoluminescence ? Or was it superheating the air as the gel slammed back together? The bullet was completely clear of the gel... So it wasn't anything left behind by that...
I’d say you know, generally lighter rounds are faster. Impressive work; certain ballistic gels like the one you’re using have more elasticity to them than human flesh. There are gels that are better at mimicking flesh, but this still gives you a good idea. Good job, again!
The temperature of a gas increases as it comes under increased pressure. Compress a gas hard enough, it can reach a critical temperature, and go boom. Same concept is used in diesel engines; no spark plugs, just a mist and compression from the engine pistons. Those little combustions are caused by gas (aka air) being sucked into the channel by the bullet's wake then being trapped, and compressed to the point of auto-ignition by the collapsing temporary cavity(s). You can see the same thing happening in slow-mo footage of (simulated) depth charges.
What's the best FMJ (grain size and fps) for 9mm self-defense? I know an FMJ shouldn't even be in consideration, but I live in backwards New Jersey. Up to this year, NOBODY was approved for a CCW license until the recent SCOTUS ruling. The remaining issue is, NJ prohibits the carrying of hollowpoint ammo except for law enforcement, with zero exception. You can have JHPs in your home, but you cannot carry or transport JHPs. With that said, what grain and fps should I be looking at?
Interesting to see that both were tumbling espacially the XTREME DEFENSE. There is a manufacturer that make special bullets/ammo that is designer for tumbling TUI Tumblin Upon Impact.
Just watched this for the first time. You might not see this. Why are you showing a different pistol at the beginning of each shot than when you show it up close? Archive video? Enjoyed it but was curious. The first is a black slide/brown frame with threaded barrel. Close up is of a standard configuration Glock. Did I miss something?
You may have addressed this somewhere else but, I think it would be good to clarify the close-up shots of the bullets leaving the barrel are not from the same wide shot of the pistol shooting the gel. Obviously, you only have so many cameras and an increasingly limited viewing area as frame rate goes up. I'm enjoying your channel! Looking forward to what you do next!
I have most of the rounds you mentioned just because i like seeing how different rounds blow up water jugs 😂. One weird one i haven’t shot yet is the arx 65gr the box says 1650 fps,it’s a weird copper polymer bullet that i want to shoot into gel. As far as carry ammo the only thing i carry is 147gr hst rounds, i load my own and have never seen one fail to open. I have loaded them on the low end of published load data and shot them out of my 43x and they still expand. For rifle ammo i use a 64gr soft point and a 55gr frangible bullet that i load. They both seem to work extremely well, compared to a vmax round the soft point just seems to dominate ime.
Lol now ya got it. Channel has great potential and some true blue gun guys will watch IF ..... you do your homework. Alot of us would love to see the standard fbi clothing gel test in super slow mo... federal hst, speer gold dot, hornady critical defense....
This is exactly what I’ve been looking for for quite some time. The advertised function of the flutes on the projectile don’t seem to function at all like Lehigh advertised them to. Rather they induce a very controlled tumbling inside the target. I don’t know why they didn’t say that, as it’s an actually tried and true method to increase the size of the wound channel unlike the claimed fluid dynamics BS that doesn’t work the way they claim. I avoided the ammo because I didn’t trust it’s effectiveness would translate to to actual tissue, but seeing the way it actually works suggests it should translate just fine. So it should not only have a comparable wound channel as many hollow points, it’s not going to get clogged or be damaged by barriers.
Weird that you're using 2 different pistols. the Xtreme defense is initially shown being shot out of a FDE and Black glock w/suppressor length barrel and then all the videos after show a straight black glock w/regular barrel. Why the gun switch?
Guys, you need to take a look on tradicional bullets like Keith's semi wad cutters, and compare it with one or two modern defense bullets! I'm sure everyone will get shocked!
Real quick I realize that when he shot the ballistics jail the second time he had a gun that had a extended barrel like a muzzle brake with a black slide and dark OD Green body but when it showed the dramatic slow motion effect of the close-up of the Glock it was a all black Glock with no extended barrel what's up with that and you can clearly see how flimsy the gun is whenever it ejects and the slot forces back but the polymer front bottom of the slide is bouncing like a rubber band
Lehigh Defense bullets, their "claims" that the fluted tip bullets direct fluids perpendicular from the tip of the bullet and create permanent wound cavity larger than projectile. The actual fact is, their bullets are tumbling, much like a FMJ tumbles, but due to the sharp features, probably do a bit more tearing when they tumble. I'd still go with an expanding hollowpoint, whether lead or copper type.
This is utterly and completely false. The reason it is tumbling is because they are using silicone-based gelatin. They need to use organic just like the FBI uses to get accurate results.
Outstanding footage! I want to point out that the Extreme Defense is solid copper. I plan to use for my deer hunting this fall, as literature shows lead fragments end up in game meat. They are very small particles, you are not getting them out. So all copper is a HUGE plus for these (no pun intended). The shape of these rounds also causes more energy to dump sooner as seen in your slow motion frames, also a great aspect. Last, I shoot into rubber mulch. It stops even rifle rounds, and for target practice I suspect I can reuse these in my reloading system a number of times. The rifling grooves may be able to be filled electrochemically, (and swage or sand high parts?). This ammo is close to a buck per round, but if my hunch is correct about the reusable nature of this design, it will be well worth it. Especially if 9mm ever gets hard to acquire down the road again (EMP, Solar Flare, stupid politics, etc.)

Low grain often results in higher velocity. Less mass to push. Have you tried Underwood Xtreme Defender yet?

Heated gelatin with a heat gun provides added clarity

The secondary detonation is called sono luminescence.

VERY Interesting and informative video! I just subbed your channel. Thanks for sharing. God bless ya'll.
Great video! What causes the detonation (when the bullet passes through) in the medium?
I was gonna ask the same. Very curious
The temperature of a gas increases as it comes under increased pressure. Compress a gas hard enough, it can reach a critical temperature, and go boom. Same concept is used in diesel engines; no spark plugs, just a mist and compression from the engine pistons.
Those little combustions are caused by gas (aka air) being sucked into the channel by the bullet's wake then being trapped, and compressed to the point of auto-ignition by the collapsing temporary cavity(s).
You can see the same thing happening in slow-mo footage of (simulated) depth charges.
Cool video. How come there's a small explosion 💥 inside the gel after the bullet passes through. What's that from. I heard you say "detonation."
It would be great if there wasn't a bunch of popups at the end of the video covering the comparison shots at 50,000fps.
Great video 🔥🔥🔥
What an amazing video, very informative and very awesome

What is causing the explosions, when the bubbles collapse?
I really want to know this too why there was an little and short explosion after an impact by bullet going through the cavity
Great video, I wonder how many caught the fact that the B roll G19 is NOT the one used in the testing lol. Great job though.

I don’t know why they didn’t say that, as it’s an actually tried and true method to increase the size of the wound channel unlike the claimed fluid dynamics BS that doesn’t work the way they claim. I avoided the ammo because I didn’t trust it’s effectiveness would translate to to actual tissue, but seeing the way it actually works suggests it should translate just fine. So it should not only have a comparable wound channel as many hollow points, it’s not going to get clogged or be damaged by barriers.
Look up "right hand rule" in reference to mechanical engineering
Weird that you're using 2 different pistols. the Xtreme defense is initially shown being shot out of a FDE and Black glock w/suppressor length barrel and then all the videos after show a straight black glock w/regular barrel. Why the gun switch?
You may know this by now but you are supposed to keep the gelatin at 40F or something while testing in order to maintain the correct viscosity
Would love to see y’all shoot a 10mm Auto through one of those body gel torso’s!!
Wow. What a fun job you guys have.
It would be cool to add a color coded inch scale on the poster board behind the gel.
Amazing how much unburnt powder is coming out with the projectile and out of spent casing at ejection.
Guys, you need to take a look on tradicional bullets like Keith's semi wad cutters, and compare it with one or two modern defense bullets! I'm sure everyone will get shocked!
Would love to see what a wad utter would do
2:52. Can someone explain why this explosion happens ?
Real quick I realize that when he shot the ballistics jail the second time he had a gun that had a extended barrel like a muzzle brake with a black slide and dark OD Green body but when it showed the dramatic slow motion effect of the close-up of the Glock it was a all black Glock with no extended barrel what's up with that and you can clearly see how flimsy the gun is whenever it ejects and the slot forces back but the polymer front bottom of the slide is bouncing like a rubber band
Keep more videos coming nice work
Thank you much!
First time viewer. Oh my God was that awesome. Please put some beef ribs in front of the gel and see what that does
Lehigh Defense bullets, their "claims" that the fluted tip bullets direct fluids perpendicular from the tip of the bullet and create permanent wound cavity larger than projectile. The actual fact is, their bullets are tumbling, much like a FMJ tumbles, but due to the sharp features, probably do a bit more tearing when they tumble.
I'd still go with an expanding hollowpoint, whether lead or copper type.
This is utterly and completely false. The reason it is tumbling is because they are using silicone-based gelatin. They need to use organic just like the FBI uses to get accurate results.
Hey man, what is the mini explosion in the block? Powder?
@3:26 why the gun is different?
Outstanding footage! I want to point out that the Extreme Defense is solid copper. I plan to use for my deer hunting this fall, as literature shows lead fragments end up in game meat. They are very small particles, you are not getting them out. So all copper is a HUGE plus for these (no pun intended). The shape of these rounds also causes more energy to dump sooner as seen in your slow motion frames, also a great aspect. Last, I shoot into rubber mulch. It stops even rifle rounds, and for target practice I suspect I can reuse these in my reloading system a number of times. The rifling grooves may be able to be filled electrochemically, (and swage or sand high parts?). This ammo is close to a buck per round, but if my hunch is correct about the reusable nature of this design, it will be well worth it. Especially if 9mm ever gets hard to acquire down the road again (EMP, Solar Flare, stupid politics, etc.)
Can you compare the Grind Hard 9mm Xtreme's to Federal HST 147gr?
So cool to see
Thanks for watching! Glad you enjoyed
