Spinning bullets on a frozen lake...

I also cannot explain it, so far I regard Angus' explaination as the most reasonable one. Some observations:
- The bullet spin is definitely clockwise. Can any of you gun nuts identify the firearm and confirm that the barrell of this model provides a clockwise spin?
- Each shot makes an impact onto the ice, however the bullet most likely bounces back when it is fired in a certain angle. This angle should be rather flat < 45°, otherwise the projectile would penetrate into the ice.
- I guess the little wall of frozen ice and snow, where the targets are located, has something to do with it. The bullet gets reflected back towards the shoote/camera guy. So there must at least 2 reflections.
- The colder the ice gets, the harder it is. I read somewhere, when the temperature reach -25° C, the hardness of ice would be the same as steel. There are no deformations visible, as I would have expected when a projectile gets reflected by a hard surface. So either it was not that cold, or the energy of the bullet melted the ice on the impact point enough to provide a "smooth" bouncing.

Another good argument for free firearms for all, so we can all recreate this little experiment in the winter!
