JMZ - Thanks for re-posting my meat and TUBE testing photos!
For The folks who are scrolling through these pics, Most of the photos are of regular ballistics gel being used to test the performance of the listed rounds fired out of the Five-seveN handgun. I did the meat and blue ballistics gel testing (which is actually not gel but waxy stuff) that you see in the middle.
The meat shown is a 22lb block of pork shoulder I purchased from Sam's Club. I did this test because I had recently purchased my Five-seveN and kept hearing all the negative information about the 57x28mm's poor stopping power. I also heard things like it is basically just a .22 magnum and you would be a fool to carry this round for self defense. I had to put an end to all the mis information and rumors my self. My results pretty much confirmed what several people on this forum had already told me. The pics speak for themselves.
I did the test on a warm 70 degree night and the meat's temperature was about 57 degrees (a lot colder than a living specimen) just before I shot it. The meat was placed 10' from the muzzle of my Five-seveN USG and 1 round of SS195 was fired into it. The white zip tie shows the bullet's path and you can see where the bullet nearly exited the meat on the right lower portion. The total penetration was just under 9 inches and the permanent wound cavity measured right at 4 inches in diameter! Yes, I said it, a permanent wound cavity of 4 inches! If you study the pics closely you will see the bullet entered almost right in the center of the block, began to tumble/yaw at about the 2 inch mark which spread the wound channel to nearly 4 inches wide, continuing for the next 6 inches. The bullet began to lose it's energy, stopped tumbling and began to go down in it's path, finally stopping facing sideways with the tip of the bullet pointing up.
If you look at the other ballistic gel testing, the results are pretty similar. Keep in mind that Pork meat is much tougher and denser than any type of human tissue.
The blue gel testing is actually a testing product called "Bullet Test Tube" (do a search for it, you can buy it yourself) and it is a waxy media used for testing bullet expansion. The test was set up the same as the meat testing and you can see similar results with slightly less penetration and cavitations, which is due to the characteristics of the wax. The company recommends you multiply the measurements you get by 1.34 to get an idea of what the bullet would do in flesh.
If you own a Five-seveN or are curious about it and need to prove the terminal performance yourself, I would recommend you try the meat test yourself. The block of meat was readily avalible and cost about $18. Thanks for taking the time to read this, I hope this helps clear up some of the rumors and/or wrong information about the 5.7x28mm.

Looking at what the SS197SR does to that ballistic gel-ain't no way in hell I'd want to get shot with it!

Next guy who says it's an overgrown .22WMR is gonna get a bonk upside the head :laugh:

I'd upriciate if you'd sacrafice a cople ss190 for a science sake :) of course.
We're planning to conduct a wide range of testing on most of EA ammo line, as well as several new loads that we working on in the mean time.

uhhh you can clearly see the fragments in the gel.

As Vitaly stated, the picture is of EA's varminTOR round. Which means it's loaded with the Barnes Varmint Grenade bullet. Which means it fragments rather violently upon impact.

Sorry, I'm surfing from my iPhone since I don't have an Internet connection just yet, I couldn't see the pics as good as I would on my PC, and I'm not spending much time reading as I should since my hands go numb holding this close up

I've been shooting and reloading for a long time, but I'm brand new to the 5.7 and the PS90.

Looks like it's a whole new ball game compared to the stuff I'm accustomed to. (Finicky?? :ponder: )

These tables are great, and I just wanted to express my gratitude to the folks who took the time and trouble to post them! :thumb:

WELL DONE! :D :D
