I think you might have been thinking of semi-wadcutters rather than hollow points. Wadcutters are specially designed for shooting paper targets, as the blunt shape of them cuts out perfect circles in the target. Semi-wadcutters are a kind of hybrid between the wadcutter and a hollow point round, an attempt to make an all-purpose round, but there have been incidents of semi-wadcutters getting lodged in the arm, and even losing most of its stopping power when going through heavy clothing.

Of course, this also depends heavily on the bullet design... there are some semi-wadcutters that are quite effective, but some have all the effectiveness of a rubber bullet.
