If the point of the pellets were hollow then they will deform more easily, however I beleive that the majority of pointed pellets have a solid front.

The wadcutter should hit almost flat and better impart its energy into whatever it hits, its also a shorter and lighter pellet thats more suited to a C02 pistol. The front of the wadcutter is closer to the hollow skirt so again, more energy and less rigidity in the pellet.

It's worth a try though, but I would stick with a light wadcutter type pellet in the Beretta.
