With the bullets landing sideways into the targets the penetration can't be very deep. In fact I wonder if it will even defeat heavy clothing (think leather jacket- even some premier hollow points have trouble there). If they landed true with the odd shape penetration will still be an issue due to yawing.
I am interested in where this goes though in its development.
Wasn't there handgun and rifles bullet developed that had multiple projectiles that were lined end to end... At least the 303 and 30-06 green tip multiball rings a bell.
Here is a 38 special end to end: (max range 10ft)
