I hope it is everything everyone has made it out to be. Purchased five boxes of ammo in three different calibers that are due to arrive tomorrow. Don't know if I'll be at the range Saturday morning or Sunday morning, but I will most definitely be there this weekend.

I just received my first order. One hundred rounds of 124 grain +p 9mm I hope to give it a go on Sunday. Easy company to do business with.

I have mixed feelings toward Underwood Ammo. For the price I think you great exceptional ammo. The downside is I think they use weak cases. I tried the 200 grain FMJ 10mm rounds in both my Glock and Delta Elite. The Glock did just fine as I expected. The Delta bulged the case more than I expected. For comparison I also fired Doubletap 10mm 200 grain FMJ through both guns and did not have a single bulged case. The only reason I can think of for the lack of bulges with the Doubletap is stronger cases used. I'm sure someone will point out the error of my ways if I'm wrong.

I also don't like that Underwood doesn't ship to Alaska so I have to have it shipped to friend in the lower 48 so he can bring it up here for me.

I know it tends to achieve and even exceed its advertised velocity. You can't say that about Doubletap.

Or less pressure from DT's weaker loadings?

Did you chrono the loads to verify that the DT was actually loaded as hot as the Underwood?

Underwood delivers on velocity most times, but that is not always a good thing. They are pushing some bullets beyond their design limits. Hence, some loadings have great expansion but poor penetration due to the parachute effect. Velocity is not the end-all-be-all of ballistics.

That would be the difference in the chamber support. The ammo is too hot for your Delta Elite. DON'T shoot any more of this ammo in it lest a case gives completely. The brass of all companies for all intents & purposes is basically the same for handguns.

Did you notice Underwood had a Delta Elite specific load(180gr GDHP) that is milder than the "normal" stuff?

All the 10mm I've purchased from Underwood used Starline brass. It's top notch brass. Matter of fact, I've reloaded most of that brass without any problems.

And DoubleTap is notorious for false advertisement.

I guess standard factory defensive ammo just doesn't get the job done and hasn't got it done for all these years.

Oh well, I guess I had better throw out all my factory ammo and get some Underwood or DT now since all my ammo is sub-standard and inferior.

you got that right bac...

i bought some of that stuff in 9mm a few years ago, did not come near the advertised velocity on the box.....and shooting from a G17...

doubletap = doubleCRAP

I don't think anybody was saying that there is anything wrong with standard factory defensive ammo, or that it doesn't perform. I don't know much about the other loads they offer, but when it comes to 10mm, Underwood is far from hype. There just aren't very many options out there for "standard factory defensive ammo" in 10mm that is true full power stuff.

My research for the best 10 mm load for my g 20 is pointing toward Underwood. DT did not cut it for what they said it would there for I will not buy from them again. Getting ready to place my first order with Underwood for my 10mm and my back up 380.

And I agree factory ammo is good for most calibers but when it come to 10mm they don't stack up to true 10mm performance, basically 40 cal. So I really looking forward to trying the Underwood ammo.

What is your definition of factory?

I haven't chono'd any of this ammo but numerous others have and it seems to perform as advertised.

As for factory ammo not getting the job done, factory ammo comes in everything from .22 short to .500 S&W Magnum. What's wrong with someone who carries a 9mm wanting a little more zip?

Not to mention factory ammo is constantly evolving and improving.

BTW I carry a 9mm with regular old Federal Tactical Bonded 135 +P.

I don't find it pleasing, that DT's ammo, doesn't achieve the velocities, they advertise, but, that is just one of their problems. My bigger concern is they still price their ammo, as though they are the only ones offering, real 10MM ammo. For crying out loud, DT is double the price, of underwoodammo.com!

Just for the record, either of their 10MM ammo offerings, whether advertised velocities are achieved, or not, in a defensive scenario, will get the job done. Whether a 135 grain Gold Dot is going 1400, or the advertised 1600 FPS, it's still going to drop gobblins!

Here is what most are not seeing. Most calibers guys can get full power from a few different big names. When it comes to 10 mm. None of the big names make full power ammo. Underwood makes full power for the 10 mm. That is why anyone with a 10 mm loves underwood. That is where the hipe comes from.

He truley gives u what u pay for. Not watered down ammo.

The reason the case would bulge from the Underwood and not the Double Tap is because the Underwood ammo is probably actually living up to the velocity claims. Or at least getting close. Double Tap is known to inflate their velocity claims.

Really though, how are any of you actually comparing any of this ammo? Do you at least have chronographs? Do you shoot for bench rest accuracy?

Just buying the ammo and running it through the gun is pretty meaningless.

I googled the parachute effect and came up with squat, nor have I ever seen it mentioned. Can you enlighten me about the parachute effect? Perhaps a link a website which describes/discusses it? I don't doubt you, I'm just curious to learn.

I was shooting underwood yesterday in a G20C; all the underwood ammo shoots good tight group's and the cases look good{star]These rounds are hot compared to factory rounds.

I just asked a good friend to chronograph my 357 Sig Doubletap 125g Gold Dot carry ammo through my G-33. Five rounds: 1394/1390/1381/1355/1390 = an AVERAGE velocity of 1382 fps through my gun. That's 530 ft/lbs of energy. Not bad at all for a compact carry pistol. Even the slowest round tested generated 509 ft/lbs.

Doubletap advertises 1415 fps from a 3.5" barrel. I'm averaging only 33 fps less and my barrel is 3.43 inches long. That difference is negligible and chrony/temperature/individual barrel variance can result in much greater differences in any caliber when tested from day to day. As far as I am concerned, Doubletap is delivering. I carry it with great confidence.

I wouldn't base my decision on whether or not to buy Doubletap based upon someone's account who had a bad experience years ago. They are performing well today, in my opinion, at least in 357 Sig caliber. YMMV.

Put me down as a fan. Their 10mm is my go to defensive G20 ammo (either the 155 or 165gr GD) and their ammo in other calibers has always performed well.

I've never seen any evidence that their Starline brass is weak.

They also have good customer service on top of having reasonable prices. Kevin at Underwood says they're going to be offering defensive loads for the 9x18 guns soon and I'll likely be using those instead of my Hornady XTP rounds once I test them.

Underwood is good factory ammo and if you own a 10mm they let it do what it can do.

Fit an EGW flat bottomed Firing Pin Stop to your Delta Elite and you will have no more bulge. A flat FPS with 18 to 20# recoil springs will slow slide opening significantly and not batter the gun on the return stroke. http://www.egwguns.com/firing-pin-stops/oversized-series-70-firing-pin-stop/ I used this in conjunction with a Wolff 18# variable recoil spring and had great result with 180 grains @ 1300 fps loads. I sold that DE to my friend back in 2007 but it is a hell of a nice gun. Nowadays if I want more the 45 ACP +P but not all the way to 44 magnum I can load 45 Super in my USP 45, Glock 21 or S&W 625 JM.

It is definitely hot ammo. Some of their loadings kind of make me nervous (especially the .380 +P as there is no SAAMI spec for +P in .380) and if/how that extra speed translates into performance remains to be seen.

I've only bought their 10mm ammo as I see no need for 9mm +P+. Factory 9mm ammo works fine.

Who said anything about self defense ammo?

Do you have to be so dramatic?



HYPE HYPE HYPE and nothing more.



If it performs as claimed, where is the hype?


Waste your money if you want to.


Let's see, for roughly $30, I can get 50rds of 10mm GD, GS, or XTP. Plus, I now have once fired Starline brass.

Again, what are you talking about?

If you read the Underwood web page for the 10mm 200 gr FMJ load, it say that it must not be used in Delta Elite or other guns without a fully supported barrel. The cases are not weak, the pressure is high. They work great in my Kimber 10mm with a supported barrel.

Sounds to me like you are not a 10mm owner. If you are, I would then say you don't understand what you have. There's no hype about something that does what it claims. This actually holds true to just about anything. If it claims to be something and it is... there is no "hype".
