10mm Liberty 60 gr Fragmenting Monolithic Copper Hollow Point fired from 4.5" EAA Witness into calibrated 10% gelatin.

BB: 585.3 fps, 3.3"

Impact velocity: 2,323 fps
Penetration: greater than 7.5"
Retained weight: N/A
Max expansion: N/A
Min expansion: N/A


The shot curved sharply upward and left the block at about the 7.5" mark. Based on the size of the track and the impact velocity, I doubt it would have continued much farther had it stayed in the block. When I first watched the video while editing, it looked like you could see the bullet leave the block and hit the water jug but I think that was just a chunk of gelatin.

I have one round left so I may test this against body armor later. The velocity seems to indicate it has the potential to penetrate it.

I forgot to place denim but at that velocity, it wouldn't have made any difference.
 
Wow, it dumped its energy quick. That would have left a crater entrance wound. I had a family member shoot a 357mag 110gr HP broadside into a doe years ago. It was loaded hot and left a massive shallow wound dropping the doe instantly. It was bang/flop. It made a mess like a shotgun with #6 shot at close range.
 
I'm not understanding this really light pistol bullet at really high velocity thinking. What would be the advantage of such a loading?
 
making monolithic bullets is definitely not cheaper, but you CAN charge double because it sounds really cool. and when people see exploding watermelon and 2 liters they think that it would blow someones chest open.

I do kind of wish more people actually DID use them for self-defense though, it would be nice to get some real world data on this new trend, just not me personally.

if attackers didn't wear clothing and you always shot them in the gut, they may be useul

It's the light weight that makes them cheaper compared to a similar bullet of the PROPER weight

Three of the 60 gr bullets would make one normal projectile for the caliber
 
I bought a box of 45 acp +p and it claims 600 flbs and 1900 fps.

To me it looks like a jacketed hollow point where they forgot to put anything in for a core. Obviously bullet weight is sacrificed for velocity. Haven't shot it yet, hard to get my brain around using this as an HD load.
 
Go for it--or do you want me to send a box to you?

I simply don't get what this ammo is really about. It looks like it dumps shrapnel in the immediate vacinity of the impact area and then sends the small core on through for deeper penetration--but's it's hard for me to figure out how that much smaller penetrating core compares with the kind of wound channel a traditional larger core bullet would make--especially upon encountering anything hard. I think it's a bit telling that the 10 mm veered off in it's path through the gel--though that just may be that one test.
 
I agree. I'm sticking with Gold Dot for my guns. No need to send that much. Two would be fine for a gel test. One and am extra in case I screw something up. A few more if you want me to soy water jugs or Kevlar or something. I'll PM you my address.
 
Or a bus, train, convenience store, sporting event, or any other place that there are a lot of people packed in close to each other, right? Because planes don't just blow up from one or two pistol rounds.

copper trades around 2.80 a pound and is even more expensive commercially, lead trades about .75 c a pound. so a lead bullet that weighs four times as much would be the same cost for material, but the price comes in the manufacturing process of all copper bullets, they aren't swaged like lead bullets, they are "turned" on very expensive, and slower, equipment. they just cost more, period, regardless of their weight
 
It's the all copper construction that makes them light and expensive. Lead is a lot cheaper.

A 60 gr lead bullet would be too small to even work in a 10 mm

I'm talking about comparing bullets of the same material, not lead vs copper.
 
Perhaps this might be useful when over penetration can never happen like on a plane.

It's a Hollywood myth that a bullet hole will destroy a plane

A 60 gr copper bullet in a 10 mm is nothing but a gimmick with no real purpose

In the good old days, when smoking was allowed on commercial flights, the aviation mechanics found minute leaks by looking for nicotine stains on the outside of the fuselage. So, yeah, even a pressurized plane can fly with a hole in it, and if it's small enough no one can tell. I think a bullet hole or two would be easy to patch without disrupting a flight much. As I understand the frangible Glaser Safety Slug was designed for use by air marshalls and is meant to minimize or prevent punching holes through fuselages.
