I am curious if anyone here has used or carried any Underwood Ammo in their EDC pistols?

I am wondering what people's ideas are about their ammo, particularly the Extreme Defense stuff.

Anything you know or heard or have experience with please share.

Never used or heard of them. What's the appeal? Specs? Price?

I've never seen to need to deviate from Federal HST's or Speer Gold Dots.

I will put up some videos from Military Arms Channel. IraqVeteran8888 also has some good videos on them.

Here is one of the videos.

It's pretty self explanatory if you watch the videos.

My current carry load is a 124gr HST. I am considering buying some of these and testing them out though.

I chose the HST on the grounds that it is a good bullet, but also I shot round after round and my gun will cycle it without fail.

That said these other rounds look pretty cool if they will feed reliably.

They are under $30 bucks on the underwood website.

Wound ballistics from this load would be no different than what you would get from any other plain vanilla flat point pistol round, with a bit larger temp cavity, but not big enough to be making any difference.

Untrained people look at gelatine and get all impressed by what they see, because they have no idea how to read what they are looking at.Source: https://pistol-forum.com/showthread.php?17091-Underwood-extreme-defender-ammunition&p=349133&viewfull=1#post349133

Like UWone77, I'd just stick with whatever Gary Roberts recommends.

Like UWone77, I'd just stick with whatever Gary Roberts recommends.

I am using 124gr HST now. Again I chose it based on reliability as well as reputation. I also do not use +P rounds.

That said my thought to try something different is based around my carry weapon. I EDC a P938 which has a 3" barrel. While I don't plan on shooting anyone but if that ever happens there are probably 10,000 other things I should worry about other than the bullet. Freaking out (or not freaking out) and having adrenaline and all that is obviously way more important.

Since I carry a small gun and will lose velocity I was kind of curious about the barrier blind aspect. Those underwood bullets seem to check both boxes.

I don't know who Gary Roberts is but then again that's why I am asking this here (to learn).

If I can get reliable feeding, better penetration through barriers, and I don't have to worry about bullet deformation or other stuff like my HP clogging up it could be viable if the wound cavity is still comparable. On paper or in a lab it seems superior but I am no expert. It might be some whiz bang new thing but then again it might not be.

I still have no doubt that if anyone got shot with a standard velocity HST, even out of a pocket gun, their attitude would change. Not sure if changing would be worth it or not.

Also never heard of them. While shooting ballistic gelatin is a good starting point, I'm an advocate of using something with a proven track record. Nonetheless, interesting videos.

I really like the underwood 147gr+p+ - it is very accurate and high on the penetration side which I want from a pistol.

Voodoo, which pistol(s) are you shooting that through. Barrel length, etc.

Thanks,

Been shooting it for years, good stuff. Well made and trustworthy. My wife uses the 147 +p gold dots in her EDC pistol. Personally I use Federals 135g +p Tactical bonded in mine. She likes the 147s because they are softer shooting. Underwood is a good company.

I am wondering if those bullets they use in the videos are effective as it appears on the internet. The actual manufacturer of the bullets is Lehigh Defense which has it's own set of ammo as well.

Those Extreme Defenders and Extreme Penetrator bullets look interesting.

I don't know who Gary Roberts is but then again that's why I am asking this here (to learn).FYI:

Dr. Roberts is currently on staff at a large teaching hospital and Level I Trauma center were he performs hospital dentistry and surgery. After completing his residency at Navy Hospital Oakland in 1989 while on active military duty, he studied at the Army Wound Ballistic Research Laboratory at the Letterman Army Institute of Research and became one of the first members of the International Wound Ballistic Association. Since then, he has been tasked with performing military, law enforcement, and privately funded independent wound ballistic testing and analysis. As a Navy Reserve officer from 1986 to 2008, he served on the Joint Service Wound Ballistic IPT, as well as being a consultant to the Joint FBI-USMC munitions testing program and the TSWG MURG program. He is frequently asked to provide wound ballistic technical assistance to numerous U.S. and allied SOF units and organizations. In addition, he has been a technical advisor to the Association of Firearms and Toolmark Examiners, as well as to a variety of Federal, State, and municipal law enforcement agencies. He has been a sworn Reserve Police Officer in the San Francisco Bay Area, where he now he serves in an LE training role.

By all accounts, HST is already pretty good against barriers, particularly for a non-bonded round. If you're really that worried, Gold Dot is bonded, and even has special "Short Barrel" versions if you're that worried about shorter barrels.

I wouldn't use the word 'worried'... it's more like 'curious'. I am somewhat open minded about new technology.

I am under no illusion that if it ever came down to a bad situation that HST rounds would change attitudes. That said if these rounds really will penetrate better and cause more damage then why not give it a shot?

To me bullet choice does make a difference but it won't turn me into a Jason Bourne Ninja.
