How powerful is it?

It's so powerful the jacket and core almost separated (this just doesn't happen with Gold Dots, not through denim)!

It's so powerful you don't measure the expanded diameter, you measure the stretched length!

That is awesome. I would like to see the same test using the same Underwood ammo but with the Hornady XTP bullet that they also offer.

My guess is it would penetrate at least 20''. That XTP isn't known for expansion...

I'd like to see the 155gr and 165gr Gold Dots tested as well.

Ummmmm, who cares if the jkt seperated a wee bit? Not I, that was friggin awesome and would do a real number on flesh. Makes me want a 10mm upper for my 21.

Just ordered some of these for a winter woods load. After reading a bunch on this offering, it would seem that Underwood has done it right for true 10mm Auto spec loads. Thank you for sharing the video!

The XTP is an excellent bullet designed for deep penetration and controlled expansion. It is one of the most accurate JHPs I've ever had the pleasure of shooting and have never had any issues of any kind with the bullet.

Obviously I am a big fan of Hornady's XTP JHP bullet (and the Speer Gold Dot). I have shot (and recovered) these bullets thru just about every type of material I can think of. I am always impressed with the consistency of the expansion and the recovered bullet weight.

I have just stumbled onto Underwood ammo recently and am excited to have another choice of 10mm loads.

No argument that the XTP is a good bullet. But, like you said it's known for deep penetration, not wide expansion. That's all I was trying to point out.

Freaking awesome! Let me rephrase that: Holy mother of Thor!!!

Bullet failure technically, but anything hit by that would also suffer failure. It goes without saying, even if your shot placement wasn't spot on, the damage caused by that would be disabling, and the bleeding would be something that won't take long to be deadly, and the "shock" factor of a hit like that alone would most likely stop a fight.

I wish LE would look back into the 10mm on the G20 platform.

(waiting on 9mm fanboy arguments)

LOVE my G20. Now, need some new ammo. Can't wait to see more test. I'd like to see the cavity left by the 135gr.

Although the test result was impressive, well, standard in my mind for the 10mm, the best part is what he mentioned near the end... he is going to train up to use the 10mm where he feels comfortable. Most people try to throttle down the loadings ( other than 10mm) until they feel good about their shooting, TN9 is obviously someone who will put in the effort to master his desired loading instead.

cowboy 1964 that was a cool test. I am interested in maybe trying the 200 grain underwood load for deer maybe if you get a chance to test that load I would really appreciate that. I think that load would have some very deep penetration! your videos are very good keep up the good work.

I wonder what he's going to test next, the 165's? When I did my own personal testing on DT's 165 it was quite impressive. I'd like to see the 135 in some balistics gel. I know it doesn't penetrate very deep, but every kind of other test I've seen done the 135 does massive damage. 155's would be interesting too. As far as the 180-200 XTP's, he will need to get another block or he's going to finally use some of those water jugs.

Interesting.

I'd never carry that load. It's way too hot and the bullet is obviously being pushed beyond it's design limits. Back off the velocity by 75 to 100 fps and maybe they will have something.

Besides, I'd be willing to bet there would be repeatable overpenetration issues with this load in the real world.

At least Underwood hit the advertised velocity mark for a change! :rofl:

Being a 10mm noob myself, how much of an issue is this jacket separation issue w/ normal FACTORY 10mm loads?

I keep hearing about how great the mighty 10mm is and I am interested in it in a full size gun, but not if jacket separation and over penetration are normal things?

Underwood has a Delta Elite specific load which is the same 180 grain Gold Dot bullet backed off to 1240 fps to allow it to be safely fired in a Colt Delta.

TNOutdoors, I would love to see this load tested as a comparison to the 1300 fps load!

Guys, this was not "complete" jacket seperation. The jacket peeled back, but stayed bonded to the load core. There was some fragmentation which is not necessarily a bad thing, and could be a good thing when you have enough penetration (17 3/4" of it).

Each fragment creates its own separate wound channel.

Devastating.

This is my EDC load. I am kinda surprised he fired several shots to get an average velocity but didn't do that for an average gel test.

BTW, in my experience, Underwood ammo has always performed at advertised specs. DT, not so much.

That would probably be a pain in the arse shoot 5 different blocks as the integritey of that particular block was mostly ruined. To shoot the same block, the rounds obviously have to stagger, the more you do this, the more penetration goes up since wound tracks overlap. This would not be much of a problem with, say, a 147grn standard pressure 9mm but not so much with the underwood 180 he used.

As 4949shooter has stated, the bullet did not fail the jacket did what it was supposed to do. Looks to me like that underwood load sqeezed the most out of that bullet. On another note, I personally don't mind some frag...

On to the overpenetration subject. Considering the human body, the skin on entrance equates to roughly 2" of penetration value, on exit about 4". That's totals 6" of penetration, give or take just considering the skin. Now let's add about 8" of media that the bullet has to contend with inside the body (slender person), that's 14" of penetration value that the bullet will have to overcome in this example. Based on the load tested, assuming a decent correlation between the gel shot and our hypothetical BG, that only leaves about 3" of unaccounted penetration. At this point the bullet is terribly deformed with a much larger sectional density thus it's penetration potential is pathetic at best. If it were to strike another target beyond your first it would barely be able to contend with clothing and/or the first layer of skin. The bullet is not harmless but pretty damn close. This is why people generally don't concern themselves with overpentration. Missing your target is your true nemesis.

Maybe not, I could only consider it from my point of view. I wouldn't want to have to store 200+lbs of ballistic gel. Nor would I want to melt one block down and reuse it on 5 deferent occasions for the same bullet test. But that's just me.

ETA: Also, I just appreciate that he is willing to do these tests at all. It must take a good bit of his time considering how meticulous he is.

09-02-2012, 08:05
I just figured if you shoot more than one shot to get a chrono average, the same would apply to a gel test. Maybe not.

I guess the old statement about " as long as you have good shot placement" doesn't matter so much with the 10MM, at least in the 180 grain Gold Dot underwood offering. :supergrin:

Could you even begin to imagine a shoulder shot, arm, thigh, crotch, stomach, or, center of mass shot, that wouldn't stop a goblin, immediately. Talk about a fight stopper. Why would anyone choose anything less? :dunno:

A couple of comments.

1) I have seen complete copper jacket/lead core separation in other bullets. This GD bullet performed as expected...especially pushed to it's limits. The recovered bullet weight was excellent.

2) This is pure conjecture on my part but a XTP bullet could possibly penetrate 18"-20" (compared to the GD 17") and pass thru a body if nothing solid was struck. This might limit it's application to something other than a self defense round against a human.

3) It seems like it is time to develop a true 10mm bullet versus using the standard .40 S&W bullet pushed to 1300-1600 fps.

Keep in mind you are looking at the bullet after it had completely finished it's path of 17" of gel. From about 2" in all the way to about 8" in that bullet was probably an inch wide if not more. It expanded to it's max and then began to peel back, but it didn't do that instantly. Bullet failure, did you see that wound track? If the bullet had failed, there wouldn't have been that impressive of a wound track. About the overpenetration....

On to the overpenetration subject. Considering the human body, the skin on entrance equates to roughly 2" of penetration value, on exit about 4". That's totals 6" of penetration, give or take just considering the skin. Now let's add about 8" of media that the bullet has to contend with inside the body (slender person), that's 14" of penetration value that the bullet will have to overcome in this example.

This is why people generally don't concern themselves with overpentration. Missing your target is your true nemesis.

Very true. For that bullet to make an exit and then in it's expanded state start to penetrate another person, it's not going to be very potent. Even in rifle bullets it take a whole lot of power to do this. Once a bullet hits an object, it loses a lot of energy as most of it is transfered. Such as in modern tanks. WWII and before the tanks were pretty much solid iron, but since then, a tanks armor consists of a multiple layers of hard and soft material. The hard material to stop the round, the soft to absorb the energy, then repeats. The Israeli tank has probably the most advanced armor type of this kind, which has taken direct hits against anti-tank misiles available to their enemies only to return fire.

3) It seems like it is time to develop a true 10mm bullet versus using the standard .40 S&W bullet pushed to 1300-1600 fps.

The only issue with that is how could that be done. I guess a smaller opening to the hollowpoint but that would decrease the speed of expansion and likelyhood of expansion. Also, the 10mm energy/velocity is pushing the limits of the lead itself. Using a harder casting of lead, which wouldn't expand as wide, or as fast. Then, either method would result in less expansion and more penetration. Like you said, I think this was an example of the limits of a GD bullet. So, the 180GD was perfect in this loading.

avenues165
09-02-2012, 12:26
That test is most impressive. I would imagine if it were to strike bone in the first half of its penetration it would create a gigantic mess inside the target. Broken bones, traveling bone fragments, fragmenting lead and copper, etc. It surely would also create a mess inside the target without striking anything solid.

If you can handle the recoil this seems like a devastating SD load. I would imagine that a double tap center mass would almost always be a fight ender.

I don't think the bullet failed, it was just pushed to the limit, with great effect.

Well he does melt the gel down and reuse it. Bringing more than one block wouldn't seem to be that big of a pain IMHO.

It IS a pain in the arse. Each test requires approximately 10 hours of my day; chronograph, opening shots, review, test shot, followup, cleanup, gel melting, video production, upload, processing. Considering that I travel on business quite a bit and I'm buried in spreadsheets and email when I'm home (YouTube isn't my real job) there are times when it takes several days to run elements of the test, then it's compiled into a short video.

The block needs 4 to 5 days to fully cure, and I'm currently rotating 2 blocks. I really can't manage any more than that, going back to time and travel. If a block is out of spec, I'm back to square one.

More shots in a test only screw up the block and increase the possibility of "crossing the streams" like Ghostbusters. That would probably invalidate everything I'm trying to accomplish.

As expected, there were several calls for a re-test. If I did that with my second block, future projects, and there are many; get pushed back a week or greater. So, I did post a water jug test following this upload, link in description of that video; it runs about 3 minutes. I was only trying to prove my theory that the velocity envelope for this bullet was surpassed.

I don't have any 10mm in the house today, other than some FMJ. Looking at .40 HST 165 gr this weekend if the rain stops, followed by something in .357 Mag, a .40 Gold Dot, then possibly a 9mm Black Talon. The only other Underwood test on the horizon is their Gold Dot in .357 SIG. Hoping to get some rifle and shotgun tests in as the weather cools.

Time for some .45 Super testing! Don't need a new gun, just put in a heavier recoil spring. I loaded some 200gr XTPs to 1300 fps. Underwoods offers some .45 Super too.

The 10mm test was cool. My one complaint about the 10mm is that driving .40 cal bullets designed for typical .40 S&W speeds isn't always a good thing. But the 180gr GD did pretty well in that regard. I've got some of this ammo too, and the 155gr version, seems like good stuff.

I wouldn't mind seeing the 135gr .40 S&W Underwoods has at 1500 fps tested, or the 10mm version that does 1600fps. At least you won't have to dig deep for it, penetration will be horrible, but destruction should be impressive.

Bullet failure technically

Actually, no. That is a Speer bullet for .40 S&W for a velocity maximum of 1295 fps, I believe. The only failure is on the part of Underwood in loading it beyond its maximum.

That being said, the bullet still technically held together.

This^^^

The test results were as I expected. The same bullet is usually going sub 1050fps in .40 and designed to perform well at that velocity. The jacket held on for dear life however it held and weight retention IMO was more than acceptable.

That is awesome. I would like to see the same test using the same Underwood ammo but with the Hornady XTP bullet that they also offer.

My guess is it would penetrate at least 20''. That XTP isn't known for expansion...

I'd like to see the 155gr and 165gr Gold Dots tested as well.

The Hornady XTP's do really well.

Retention of 177grs at that velocity might be technically called failure but in my eyes that bullet is the only one capable of that "much" of success. That might be one of the most effected rounds I have seen tested in a while, makes me want to shoot more 10mm. If only I could win the powerball......

I will carry proudly and take that extra split second if possible of what is behind my target if the going ever got tough. I was very impressed with this Underwood ammo. I want to get some of their 200 grain for woods carry.

Thank you again Awesome video:perfect10: all the WAY

Not sure, I figure it is close to 1350 give or take... but that is only a guess. We have finally purchased a good chrono so I will chrono them in a few weeks to have a solid number.

I got my 180 GD loads over the chrono last weekend and I'm getting an average of 1240 from the stock barrel. 1330 from my 6".

These are the book max blue dot loads from the Speer manual.

I'm waiting for the 45 ACP 230 gold dot +P test, hint, hint.

The .45 ACP doesn't have to expand to be effective. It is already at .45 caliber.

If it does not have a proper nose shape it won't be that good,
think large flat point.

When I carry my SA M1911A1, I use 255gr LSWCs at 850 FPS.

Thanks to cowboy1964 and everyone else who contributed to this thread as I have just purchased some Underwood Ammo 10mm 200gr XTP ammunition if it were not for this thread I would not have been able to buy the ammo. I guess I got lucky as everything else I looked at was out of stock on the site.

I HATE THE PHRASE BULLET FAILURE!!! I mean... you can hear the almost disbelief, he is choking in his voice upon seeing the damage that HANDGUN round did to that gel and then says "Well, mixed feelings here because technically the bullet failed." GIVE ME A BREAK! It had mild jacket separation. It did not "fail" its intended function in devastating its target. It did not fail to penetrate sufficiently.

Guys do you think Underwoods 180gr DE load at 1240 fps perform better or the same.

Mild jacket separation? The bullet was compromised due to excessive velocity, driven past it's design envelope; regardless of the damage.

I will add that I made a necklace out of it and it does a great job of attracting biker chicks.

That is awesome. (mentally picture Homer Simpson drooling) "Biker Chicks..."


I still contend that the Gold Dot in your test did not fail. A meteorite by any other name, is still a frick'n Meteorite !! A massive hunk of jagged metal, ripping through muscle, fat, bone, and organ...
