Ok video, but I don't agree with the wording they use at the beginning.
FMJs are not designed to create a bigger wound. They are designed to punch narrow, relatively clean holes straight through. They do create a deeper wound, typically penetrating all the way through the target, as the video points out later.
Hollow points are NOT designed to fragment! They MAY fragment, especially if they are of older designs, but that is NOT their intended purpose! The video later points out the real purpose -- they expand in order to create a wider wound path that has more tissue destruction and more chance of hitting something vital, thus increasing the chance of stopping an attack.
I'm one and the same as gb_in_ga, so add a bit over 900 to my post count...
