Winchester Ranger 147 gr SXT
OUCH!
Let me say first of all... that looks absolutely vicious. Ouch indeed. If you could get this expansion without the jacket separating from core, a single hit to any part of the body (except maybe the limbs) is going to cause catastrophic injury.
I did a thread about 9mm ammo awhile back. I absolutely love 9mm and I try and "collect" a sample of as many kinds as I can find. For self defence, have a look at these (some people have mentioned them already):
Remington Golden Sabre 147gr. This is Remington's top of the line bullet. It is a brass (rather than copper, for you newbies) jacketed hollow point.
And have a look at the price. Yaowzah! I just bought one box (on sale for $26) to check it out:
This is the Golden Sabre compared to two other Remington 9mm. The 115gr. +P bonded jacketed HP is another really smoking round. When you fire that stuff you think, "Yah, this would work". It has some omph to it, to say the least.
From this angle you can see that the Golden Sabre and the +P bonded jacketed hollow point have a longer overall length than the others. The regular UMC stuff seems to be seated lower in the case than many brands though (although I also find it to be by far the best "pratice ammo" on the market - for the price). Left to right these are:
Golden Sabre 147gr.
+P bonded jacketed 115gr.
UMC 115gr, HP
UMC 147gr. flat nose MC
UMC 115gr. round nose MC
From this view you can see that the "cavity" on the Golden Sabres is huge. It also has that look to it that makes you think (or hope) that it will expand back in individual strips, like in Ronin's photo. This is where bonding to the core becomes important. All bullets flatten out and expand if they hit something hard enough. What you want is maximum expansion without having the jacket ripped off of the core.
Here are some more garden variety 9mm:
