Josh over at Barnes was kind enough to send me a CD with their data. I broke it up into individual bullets, but the documents are still pretty large, so it'll take some time to download each document. Enjoy...

Great stuff!

I don't suppose i could prevail upon you to get some data on the 200gr XPB bullet?
Zhukov
04-24-11, 21:01
The only 200gr bullet in the list is for .44spl.

Josh at Barnes provided the info to me, FWIW...

Ah, okay...perhaps you could pm me his contact info and I can bug him about the load I'm playing with

Thanks for posting this! Why is it that the .40 actually had MORE penetration with the car door test? The wound cavity wasnt as big but thats pretty impressive penetration

Because without the petals you see in regular expansion, there is less resistance to the bullet, allowing it to penetrate deeper. The expanded hollowpoint increases drag, one of the main reasons for using a hollowpoint, that both allows it to address more tissue and causes the bullet to lose momentum faster, keeping the bullet in the body and reducing overpenetration. Think of it like a parachute effect.

The reduction in diameter of the wound channel is due to the same effect- no expansion, less facial surface area to disrupt tissue, smaller wound cavity.

Thankk you. I was thinking that but I didnt know for sure.

Interesting, with one caveat: How does a Grendel get a 120gr bullet to 2700fps? Alexander Arms' own ballistic chart shows a 24" barrel topping out at 2600fps...

http://www.alexanderarms.com/grendel_ballistics.pdf

For that matter, how do they have a 5.56 launching a 55gr at only 2561fps?

Seems the setup was a bit odd.

It appears the purpose of the tests were to show differences in bullet construction (in the 5.56 tests specifically) without bias from velocity. I've loaded the 70 gr TSX and was easily able to get 2800 fps from a 20" M16 without seeing any pressure signs.

So with the 70 gr TSX penetrating almost 5" more than the 55 gr was penetrating --consistently, it shows that the added mass aided in penetration regardless of velocity. Call it a bit of a control in their tests.



I admire they kept the car door results which show the petals being sheared off and part of the car door merging with the bullet to increase penetration slightly.



very good post and thanks, zhukov

I shot this 150 pound hog at 225 yards with a handloaded Barnes 70 grain Copper TSX bullet and recovered the bullet under his skin on the far side, it definitely worked very well.

Entered behind his elbow and stopped under the scapula on the far side, DRT.

Thompson Center Contender with custom MatchGrade Machine 20" barrel with 1:7" twist.

Congrats on the hog! Looks like the TSX did its job. What was the bullets recovered weight?

Have not had the chance to weigh the slug but I will, bet it weighs at least 98% or more.

The bullet certainly performed as advertised.

The slug weighs 69.9 grains, cannot beat that!:dirol:

Dang impressive!! Thanks for taking the time to weigh it.

It very well could have been its weight. No doubt.

Now, if he'd've shot that with an AR, we'd at least know where tactical bacon comes from. :D
