357 sig Underwood Ammo Test (65gr Xtreme Defender VS 125gr Gold Dot) in Ballistics Gel

[@joejones1779]

It's kinda funny that a under powered .357 sig rounds, is still way more powerful and damaging than most other rounds. Just shows how potent this caliber is. Thanks for the test. Have a wonderful day.

[@AzAirgunner.]

Thank you sir, you have a great day as well!!

[@nikos6220]

I run the 65 grainers out of my 5.3‘ Glock 35. nice to get confirmation that that is a nasty round. cavity volume is probably 2x the GD!

[@louv4437]

You have an awesome combo bro about as good as it gets to stop a bad guy

[@maxmccain8950]

Any feeding issues? I still wonder about them hitting the ramp on a flute one round and a ridge on the next. They sound kind of clunky going in when fed from a locked back slide.

[@nikos6220]

Awesome test. The disruption on the Defender was nuts! I was on the fence about picking up the 65gr Defender rounds. Not anymore, ordering a box this week. Thanks....

[@angrysheepdog9744]

That 65gr wound channel is wicked. Looking forward to a comparison test between the 65gr and 90gr XD. The Joint Agency Ballistics Handgun Ammunition Test 2016-2017 favored the 90gr due to barrier blindness. Search it YT blocks the links

Thank you, I appreciate it!!

[@c.r.chandler5905]

My word, AZ. That Xtreme Defender is just something else. I've always wanted to carry a rifle in a high ride holster. The ONLY thing that worries be about the defender is that amount of penetration. The disruption was nasty but I shudder to think about someone standing behind the intended target

Thank you!! Yes, I will be testing 5.56/.223 soon also .308. Just have a ton of handgun calibers and ammo to get done. Thanks again!!

[@rangetime6779]

Another great test. The 65 XD has a tendency to tumble and not track straight. I choose the Gold Dot. The added momentum also helps. If you shot a steel plate the GD would swing it more.

[@ryantogo8359]

So would throwing a baseball at it. Doesn't mean the baseball is gonna kill quicker lol. Flawed thinking. And no indication that it tumbled lol.

Does the Secret Service still use 357 Sig or did they do the same as the FBI? Is their any LE that use 357 Sig?

[@aleintstein]

I have seen over the years the 357 sig 65 grain get 2200 FPS out of same size (4.5 inch) barrel or even 4 inch. So would agree this lot is much lower in power.

[@angrysheepdog9744]

An interesting comparison would be 357SIG/65-68gr vs Speer 223/62-64gr soft point out of a 10-12" pistol carbine

[@AzAirgunner.]

I have the 55gr speer and a 10" barrel🤔. Thanks for the idea, sounds like a fun test.

[@kennethferguson4283]

You are correct Underwood does vary somewhat in their loadings from one batch to another. You could actually do the 357 Sig folks a favor by testing their new batches to see how hot each batch is. Example the batch of "68gr" XDs that were put out last year were 150 fps faster than what you just tested. Several people found out about this on the interweb because of an individual who posted his velocity test results, the batch sold out shortly thereafter, with myself aiding the sellout!

[@AzAirgunner.]

I will definitely have to do that. Thanks buddy!!

[@kennethferguson4283]

@@AzAirgunner. The batch number on the 125gr GD looks to date back to around 2020. The batch number on the 65gr XD would date it back to around 2018. Underwood introduced their XD round in 2015.

Nice. I definitely will soon. Should be a fun one. Lmk how it goes out of the longer barrel.

[@guardianminifarm8005]

These are both winners for personal protection. Not sure I would choose the Defender for bear protection. But I might consider the Gold Dot for black bear if I didn't have a larger caliber handgun. Thank you Sir.

[@patrickferryman6579]

Wherr did you get the gold dot round? I cant find them on the underwood website anymore.

[@curlybill3966]

They use Nosler now. It’s a good bullet, flattens but stays together.

[@Texas2Step79]

I feel like the 65 grainer would deflect off hard objects such as bone.. think I still like the 125 grainer best ..

[@eddiearchuleta615]

The old 65 grain XD is way underpowered the new 68 grain is going 2200-2230 from a g31 2300 from a 5 inch

[@ryantogo8359]

Yep

[@TERMINAL-BALLISTICS]

Great video, but I'm a bit confused. How are you arriving at the conclusion that these rounds were below advertised velocities, when you're not even replicating the FBI ordinance distance from the gelatin block? FBI specs notate that the requirement is 10 ft from the block. Not 15.

[@DonDeMarcoKarlsruhe]

The most anticipated on paper!!!! Let see how it performs in real world....... Black Hills called honey badger second gen of that kind of ammo is even better because the improved bullet shape. I hope Wilson Combat will improve soon that screwdriver tip bullet design even better (3 gen).

[@TERMINAL-BALLISTICS]

Lehigh invented the design and it's absolutely impeccable. Improved shape? How so? The XD's shape was specifically engineered to centrifugally impel surrounding tissue outward as it deposits it's kinetic energy and that's precisely what it does (exceptionally) in the absence of expansion. Black Hills Honey Badger wouldn't even exist if it weren't for Lehigh's revolutionary design.

[@TERMINAL-BALLISTICS]

lol at Wilson Combat. They're bozos compared to Lehigh when it comes to projectile engineering. Have you seen their new fracturing bullet? It's a glorified version of Liberty's Civil Defense and they act as if they reinvented the wheel. They'd better not change the XD design, cuz it will be the downfall of a superior projectile.

[@TERMINAL-BALLISTICS]

Anticipated "on paper"? Were your eyes open when this video was playing? Because the cavitation from the non-expanding/barrier-blind XD absolutely smoked the 125gr HP. That degree of performance doesn't just go away in "real world" scenarios.

[@DonDeMarcoKarlsruhe]

@@TERMINAL-BALLISTICS Ok i understand Leigh invented the design and they are the most capable to improve it.

[@DonDeMarcoKarlsruhe]

@@TERMINAL-BALLISTICS Honey badger is 15-20% superiour to the first gen extreme defender. That was already said at the gun show years ago from Black Hills himself. Interesting will be a ballistic test with those kind of improved bullets (when they are fast enough) out of a longer barell because the higher spinning. Or the Black Hills 357 or even the 45/70. Those bullets look meaner even when they dont move... Just imagine that 45/70 copper with higher and sharper edges touching a ballistic gel. Because its light for his caliber the energy transfer in that 5" to 15" inch area would be better than something else on the market today. A 45/70 rifle is allways lighter and handier than every modern shotgun and could be even more effective that a 12 gauge Brenneke Black Magic. For dinosaur hunting only 🤠🤠🤠🤠

[@ultrafuel2559]

I wonder how different chronographs would compare? Gun Sam_Revolver Aficionado clocked the Grizzly 90gr 357 Sig at around 1900 fps, while you got a max of 1842 fps for the Grizzly in an earlier test (could be barrel length). Your results are also considerably different than what I got from a friends chronograph. I chrono'd the 357 Sig 65gr Extreme Defender out of my 3.5inch barrelled P224 at 2126fps, 4 inch Glock 32 at 2178fps, and 4.4 inch P226 at 2289fps. These were the max velocities of two shots each. The P224 is my daily carry, and I carry two Grizzly Ammo 90 gr on top of 4 65gr Extreme Defenders and 4 115gr Extreme Penetrators. I think the Extreme Defenders are superior, but my concern is the potentially liberal progressive attitude towards exotic bullets if I end up in court. Grizzly Ammo rounds use a conventional hollow point, but are still very powerful (near hot 10mm energy) as demonstrated in both previous test. My assumption if I have to shoot more than two rounds I'll be shooting through some kind of barrier. I started carrying the Extreme Defenders/Penetrators after the truck attack in France. They won't stop a truck, but I suspect they will be more effective if I have to shoot through car glass and car doors.

[@BillHimmel]

Of all the .357 sig and .40 cal ammo you tested so far, which one would you personally use for real-life home-defense?

[@nickadkins7765]

He just did a 357 sig test with the Underwood 124gr Nosler projectile and the Underwood 125gr bonded Speer Gold Dot, and if I remember correctly he preferred the 124gr Nosler round. They just exolode upon entry and create some carnage that would be a surgeons nightmare. I run that Underwood 124gr Nosler +P+ in my 9mm and a factory loaded 125gr bonded Speer Gold Dot in my 357 sig. Might have to pick up a few more boxes of that 124gr Nosler for my 357sig though as that test he did the other day proves it's extremely devastating!

[@AzAirgunner.]

For 357 sig I actually like the 125gr Federal HST quite a bit, definitely one of my favorites. I have a ton of tests on it. As Nick said I very much like the 124gr nosler loaded by underwood. It's one nasty round for sure, always performs great. As for .40 s&w I really like the 180gr Ranger t-series. I have a bunch of tests on that also and it seems to do really well in short and full size barrels. Another one I like for .40 is the 155gr Federal HST, it's been discontinued but I have a good supply stash for a rainy day. I like em all though lol. Thanks for checkin this one out😁

[@justusbryant7366]

Handgun rounds are handgun rounds. Has to be over 2200 ft per second to cause and explosive tissue damage. All you need is a good penetrating round. People die from blood loss from handgun rounds. They just poke holes. People get to cracked up about the ballistics on these rounds.

[@TERMINAL-BALLISTICS]

False. Irrespective of handguns or rifles, projectiles traveling at velocities exceeding 2,000 fps (not 2,200), can rupture surrounding hematopoetic / vascular organs through the process of shockwave dynamics, which extend to areas well beyond the permanent wound channel itself. Let me know if you wanna learn some facts pertaining to wound ballistics, or if you'd like to see some peer-reviewed scientific literature by actual trauma surgeons that legitimize my statement.

[@eddiearchuleta615]

[@TERMINAL-BALLISTICS]

@@eddiearchuleta615 I agree that the 68gr are typically hitting higher velocities however, it's worth noting that there's videos on KZbin showing averages of +2,200 fps out of 4 inch barrels with the 65gr.
