Here is a good example.
A local Police Dept here in my area wanted some ammo that was the best effective man stopper they could get.
They wanted something that caused massive tissue damage and did not over penetrate.
This ammo shown was like the Eagle Talon made by Winchester some years back, The bullet mushroomed with sharp edges.
After they had it for awhile they finally used it on some bad guys and the doctors at the hospital told the Police dept that they would not treat gun shot victims, shot with this ammo.
It seems that it cut their rubber gloves and the doctors hands when they tried to remove the bullets from the bad guys.
The Police dept traded in all the unused ammo and got new ammo that was doctor friendly.
The public got this stuff at a great deal ($10 per box of 50).
It is excellent ammo and shoots great.
