In theory there is no difference between theory and practice, but in practice there is.

Looks more like a .38 than a .40 caliber.
That being said, it looks like a small percentage of his shots bounced off the ice rather than penetrating. Given the low angle, that's not so very surprising.
These ricochets come to rest as objects spinning very fast, but not translating very fast, on the ice. The rapid spin causes a very localized and small amount of friction heating, for a thin film of water between bullet and ice.
Wet ice has a lot less friction than dry (try driving on wet glare ice sometime). So, the spinning bullet does not slow down very fast.
There is some chance you will have a spinning ricochet come down close enough to see before it quits spinning. I suspect the chance of being directly struck by the ricochet is at least crudely similar.
All in all, not an experiment I'd recommend. But interesting, nonetheless.
