Interesting article in new American Rifleman on page 44
It's in thirds across the tip like the quick-shock was. Three 'petals' break apart radially, leaving the base as a blunt slug being the fourth piece. My earlier post's numbers were wrong because I didn't allow for the weight of the base piece. The three petal segments would be even lighter than I allowed, more like 20 grains or so each rather than 35 grains. And considering that the bullet would have to be at less than muzzle velocity by the time the petals broke off to begin with, they'd be more like a triple-tap with 22 shorts than 22LR.my browzer wont blow it up to read it. but it looks like they segmented it crosswise...
