Today I tried a highly unscientific expansion test of the Fiocchi 92gr EMB from one of my M&P9c's. I will admit to being a little concerned about using such a light bullet out of the 9c's short bbl. I used 3 1-gal water jugs in full contact, presenting 18" of medium (I thought 2 might be sufficient w/the 3rd for a margin of safety). Fired a single shot from 10', impacting the center of the first jug. Surprisingly, all 3 jugs exploded w/the third showing an exit hole out the back (shucks and other comments!). Having deliberately set up the jugs so line-of-travel was easy to determine I decided to hunt out a bit along the bullet's probable track to see if I could locate it. I'd barely looked down into the mud when I located the expanded bullet just inches away from the third jug's location. Apparently the bullet had just enough energy to barely punch out the back of the third jug and no further. Expansion was a full & classic mushroom measuring .64" at the widest w/full weight retention (the bullet is entirely copper & bronze). I realize this test is highly unscientific under ideal conditions but still I find myself impressed w/the level of expansion & depth of penetration from a short bbl.
