Both are pretty neat!

Did you see the other 140 gr with the 3 segmented petal HP?

Underwood Ammo's 10mm 140gr Controlled Fracture round. Made with Lehigh Defense's Controlled Fracture Bullet, this round offers a sure-fire, replicable pattern every time. These bullets are solid copper and pre-stressed in three particular areas to allow the petals to separate from the bullet base. At the specified penetration depth, the petals separate from the base, releasing an energy spike, and expand from the primary path of the bullet. The bullet base continues penetrating in a deep straight line along the initial path.

Jeff Quinn of Gunblast.com did some interesting ballistic testing of this Lehigh Defense projectile bout a month ago:

Although interesting novelty, at $1.70 & $1.80 per cartridge, believe I'll pass.  Kind of sorry to see
Underwood finally marketing 10mm products at pricing levels right up there with Buffalo Bore & Double Tap.

 Received them today:




Added the 180gr XTP as well:

Nice, those look like they would screw things up!  But phillips head is so old school, need Torx head...

The others (CF HP's) could be called Triceratops or Tri-CrerFlops!

Both items from LeHigh Defense are supposed to be added to the catalog as component items for reloaders. Considering they are solid copper, you could use them in California for hunting deer in the lead free zones.

I don't know if carried by 6 or tried by 12 would be any better if you use these. Don't get me wrong in a gun fight there is but 1 rule win. But life in prison when you could have just used good Hollow Points to me would bet easier to win a case because every cop in the USA uses them.  But I guess there isn't any difference in CorBons Glaciers or is there? Think I will wait until these are used and the person is tried before I will carry them. That was always the strong point of being the baby of 7 you get to learn from your brothers and sisters screw up. Mostly.

Honestly if these prove to be superior I'll carry them. I want the best thing I can possibly have. You had it right when you said the key was to win. Besides, chances are you'll never have to use your CCW in your life. I'm not worried about the courts. I always find it funny when someone I know is carrying FMJ or Federal classic or some generic crap. "But Gold Dots are expensive."

[Pinsnscrews]

The xtreme penetrators are meant for the Handgun hunting crowd. The HP's are for defense. I wish they would make the 220gr they have for the .44mag in 10mm. I would give up some powder capacity for those puppies on a deer or elk. I think 1100fps could still be possible out of a 10mm case.

Dave;

Totally agree - I want to carry and keep the absolute best for self defense.  My thought is if you can't afford the best, you REALLY can't afford the gun then!  My God, what are you saving it for anyway??

Right on "if these prove to be superior" we'll all be caring them.

However at this point; interesting, expensive novelty.     

Really looking forward to test results of these Lehigh projectiles in 10mm fired into calibrated ballistic gel (by people not trying to sell anything) using FBI protocols. 

In the meantime several very well established projectile options; all with potential to be devastatingly effective in 10mm readily available.

   I decided to play hooky today and have an extended range session. The weather doesn't look too good for a while and I deserve it

  As usual with just about all Underwood it meets or exceeds the rating. I'm betting these 140's are the same load/powder for both.
