105 gr DRT fired from 4.5" barrel EAA Witness through into calibrated 10% ordnance gelatin.


BB: 590.2 fps, 3.6"

Impact velocity: 1,415 fps
Penetration: 7.1"
Retained weight: 0 gr
Expansion: N/A


Obviously extremely shallow penetration and not suitable for defensive use. Still kind of a cool round, though. The star like appearance of the stretch cavity is pretty cool looking.
 
Yeah, that's a pathetic round. Only 1400+ fps from a 10mm? Again pathetic.

Underwood has a 40sw 135 JHP that'll do 1400 fps. I carry UW 155 which is 1300 fps myself. :cool:
 
I expected more velocity out of that weight bullet. I've pushed a 175 gr lead bullet to 1400 fps out of a G20. Maybe that velocity coupled with the construction of that bullet is why it disintegrated the way it did.
 
Yeah, I'm really surprised at the velocity too. I opened this thread thinking "I bet that 10mm round was over 2,000".
 
this is my opinion but I would not use any specialty ammo for self deference. Id go with a proven round by a major manufacturer. I cant imagine facing an antigun jury after using "Dead right there" ammo. That is just asking for trouble.
 
I don't think the 10 was designed with "lightweight" bullets in mind--I think about 155 was the bottom end envisioned. I recently bought some "boutique" 45 acp that also was being touted by one of my LGS as the next greatest thing (aka "here's a sucker we can unload this crap on")--they all seem to be doing the same thing--pushing ultra-lightweight bullets and ultra high (for the cartridge) velocities. At what point does ammo like this just become "guaranteed to maim?"
 
Did anyone watch the same video I did? Muzzle velocity wasn't measured, impact velocity was measured. The chrono looked to be at least 15 feet away from the muzzle. Advertised velocity is 1541 fps.
 
15' doesn't make any notable difference in velocity, the distance was actually about ten feet, and that's where "muzzle" velocity is always measured. If you shoot too close to the chronograph, it can produce erroneous readings.
 
I'd like to see how some of the DoubleTap ammo does in gel if you get a chance. I've chronographed some of the 200 gr hardcast @ 1315 fps from my G-20. It is advertised at 1300. I also have some of their 200 gr HP ammo advertised at 1250 fps, but I've never shot it over a chronograph. The hardcast should penetrate deep, but I don't think I've ever seen any actual data.
