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
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.
If you guys are mystified by a lighter projectile traveling at a higher speed then I'm not holding out much hope for the video, Lol. Also, you might want to reference that it's a Lehigh bullet as loaded by several ammunition manufacturers. Post viewing - great footage nonetheless, thanks for that, and I also saw your pinned comment providing your explanation. Good that you got that sorted.
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 spy an fde frame with threaded barrel shooting the gel then I see a regular 19 when showing the rounds come out the muzzle I wonder if that would affect the velocity with the extra half inch of barrel 😁. Love the videos gents!
Their Extreme Defense rounds look very much like Underwood's Extreme Penetrator. The flutes in Underwoods Extreme Defender are significantly deeper. (More pronounced)
This is the cleanest and most clear slow motion footage of gel ballistics I’ve ever seen. I’ve scoured the internet and RU-vid looking at these videos, to the point where my wife now hates RU-vid. 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.
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.
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!
@@BallisticHighSpeed you are the most amazing channel on RU-vid. I absolutely love you. You truly are the best. In a few years you will reach more than 1 million subscribers
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
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.)
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!
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.
@@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. 🇺🇸🇺🇸
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.
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.
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!
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.
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.
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 🏴🤔😇🏴
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
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?
"Somehow the lighter bullets fly faster"... NO WAY!?! YA DON'T SAY?!? Like seriously, even without middle school physics knowledge, any gun owner should know that lighter bullets are faster all else equal smh
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!
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.
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’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. 🦅🇺🇸
video request can you do 126 +p federal HST or 147 grain federal HST 9mm to compare against the xtreme defense bullet (they say underwood is the best of all extreme defenders fluted bullets)
Is it just me who sees different wapon being shot in normal speed and in slow mo? I mean, there isn't even any disclaimer. It's like setting a speed record with white and dirty Ford Focus and then filming the "cool" stuf with red Lambo
Likled thhe channel im subbed.... but i have construtive criticism..... if you guy are going to be guns and slow mo you need to get WAY more educated on the weapons, ammo, and ballistics. Its very cool just to watch but youll gain a shit ton more subs if you get more technical. Like calibrated ballistic gel testing of different defense and duty rounds. But youll need to know more of the basics or people will look right over
Hi Adam , hi Bryce , can I ask you to put metric speeds as well ( m/s ) for all future videos, Europe is watching too not only America, and i think that a lot of bullet and firearms companies are using metric sistem for diagnostics. Thank you if you read my post. Hello from Croatia
Got to be honest - I’m not sure people who don’t understand what the grain of a round means should be presenting themselves as a ballistic expert comparing rounds on the internet 🤷🏻♂️ Cool footage though
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....
I like your content, but why does the video show different firearms being used for full speed and slow motion shots? Green lower with a muzzle device vs all black, no device on slow motion?
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
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?
Why the hell are you heating the block? You guys still have alot to learn, especially with grain weights. Those detentions only happen in the clear ballistic gels as well.
This channel would be so much more effective if the hosts had even a moderate amount of knowledge in relation to the topic. They seem to have done zero research on the material presented and rely entirely on the high speed imagery.
Lol Just seen that slide slider along the top of your hand and then when it goes across the top your hand because in between the handle grips and the slide I seen it get rubbed pretty good I’ve gotten slide bite before it fn hurts like hell from a nine mill
