They are offering plenty of crazy velocities that appear to be legit from people testing their ammo.
I saw a 9mm 147 gr +P+ that was listed on their site at 1175 fps. 380 90 grain ammo listed at 1200 fps. I know they have a 135 grain 10mm offering that is supposed to go 1600fps. So are they just loading super hot/high pressure ammo for people that just want to chase high velocity numbers or what? Kind of reminds me of buffalo bore.

I just ordered 3 boxes and plan to shoot them up this coming weekend. It took 2 days to arrive on my doorstep once i ordered them.
Found this guy on youtube with several reviews of Underwood ammo http://www.youtube.com/watch?v=gQ7ri9wa728&feature=plcp |

Wouldn't this question be more appropriate in the Ammo forum since it has nothing to do with individual shooters reloading?

I thought maybe someone here had an idea as to how they were getting the higher than normal velocity. It wouldn't bother me if Aero or Dryflash wants to move it. |

147 grain 9mm at 1175 fps is 25 fps slower than VihtaVouri's published load using 3N38. Same with other cartridges listed. Savvy handloaders research their loads. Apparantly this company has done their homework.
It's not rocket science. |

Apparantly this company has done their homework. It's not rocket science. Pretty much every one else 147/9mm offering goes 1000fps. All my reloading books max out with 9mm/147 at 1000fps. Call me a skeptic, but I'm suspicious when one particular powder combo is that much higher than what anyone else is doing. If it was as easy as using max charges of VV3n38, then why aren't the major ammo companies producing 9mm 147 ammo that runs 1200fps? |

I guess what I mean to ask is:
If these people are routinely getting 150-200 fps more out of rounds than major ammo companies are getting, are they using propriety powders, duplex loads, or just exceeding pressure standards? |

Not everyone does it because not everyone needs the extra punch or recoil. Like the people I only have this gun what round for hiking around dangerous animals. Well now you got a hot +p+ round in 9 that you can't get anywhere else.

I ran their 10mm ammo thru my G29 when I had it. All high quality, and hot like it should be. The 10mm guys all raved about Underwood, full power loads and the prices where/are great.

My guess is that they are going right up to the edge pressure wise, using the powder best suited for velocity, instead of economy. Factory loads are usually below SAAMI max. Plus, they are loading millions of rounds, and load for economy, even if means sacrificing a few FPS. |

I got two boxes of their 357Sig 125gr Gold Dots. They are supposed to do 1475fps from a 4" barrel.
tnoutdoors9 (the guy on Youtube) said on another site that he has a few boxes of these and will soon chrono and test them in his usual fashion (4 layers of denim and Simtest media). I just got mine and haven't shot any yet. |

Like other cartridges, velocities seem to have fallen with the passage of time. This perhaps explains why some people insist that 357 SIG doesn't go much faster than 9x19 +p. It takes a very special bullet to perform at these velocities. |

I want that particular caliber for what it was designed to do: mimic a 4", .357 Magnum 125gr SJHP ballistics. |

I have shot the 357SIG ammo from Underwood and they live up to their reputation. They are very hot and extremely accurate.

Because the 9mm 147 Federal HST or Winchester T of bonded seem to have enough penetration. And without the extra blast and recoil. About the same reason why I gave up on the 125gr 357magnum loads and moved to the 38spl+P I could put more rounds down range faster and have a smaller group. |

TNoutdoors9 test of the new "improved" Underwood 125gr 357Sig is up on YouTube. It AVERAGED 1511fps from a Glock 32!!! (4" barrel)
It was the 6-petal Gold Dot designed for deeper penetration. It penetrated 15" and expanded to almost .57" in SimTest gel media after 4 layers of denim. Quite frankly, I think that high of a velocity is wasted on a Gold Dot. I'm not a GD fan, so take with a grain of salt. I'd like to see a bullet that would act more like the .357 Magnum SJHP, i.e. extreme deformation and yes, maybe even a little fragging. That Gold Dot didn't look any different than any other expanded Gold Dot in 357Sig despite the screaming velocity. Maybe using a 9mm GD would help, or a Sierra, maybe a Nosler. Otherwise why deal with the recoil and blast when the bullet looks the same in the end? Yeah, it had a helluva stretch cavity but still..... |

I've been using Underwood in both 10mm and 500mag. It's definitely the hottest production ammo I can find in both of those calibers. Kevin is also a great guy to deal with and always has time to talk on the phone.

I really want to try their 230 grain .45acp loads rated at 1,000fps but am hesitant. I want some more feedback from users shooting Springfield Loaded models to see if they can tell any abnormal wear from these loads. A 230 grain bullet at 1,000 fps is almost .45super velocity and energy.
