I remember there was a thread about this ammo but couldn't find it.
9 mm Fiocchi 92 gr EMB
We had a chance to look at the Fiocchi 92 gr Expansion Mono Block this week; as can be seen, it was less than impressive...
Fiocchi 92 gr Expansion Mono-Block (9EMB) fired from G17 at ave vel of 1315 f/s; 5 shot ave below:
BG: Pen = 12.6", Ave RD = 0.56", Ave RL = 0.54", Ave RW = 93.5 gr
4LD: Pen = 16.1+", Ave RD = 0.36", Ave RL = 0.55", Ave RW = 93.5 gr
Here is a photo showing how full of fail the EMB is, top row is fired into BG, bottom row into 4LD:

Even if the EMB works perfectly, it is still problematic. The expanded portion of the EMB is far behind the leading edge of the projectile. The temporary cavity forms at the leading edge of the projectile--in the case of the EMB, at the front of the upright post, much like first generation Hydrashoks with the large thick center posts. Think of the EMB like a Hydrashok on Viagra. The TC forming at the front of the erect post can result in the tissue being stretched away from the expanded jacket at the back of the bullet, thus preventing the expanded bullet edges from touching and cutting tissue. With deforming handgun projectiles, the expanded bullet edges need to be as close to the leading edge of ther projectile as possible for maximum tissue disruption to occur. Unfortunately the EMB fails in every way...
