Gentlemen, don't worry about a .450 bullet @ 1900 doing a lot of damage on roe. In fact, it is less damaging than most "standard" rifle cartridges like 7x57,30-06 or 8x57. The slow, heavy bullets don't meet enough resistance in our tiny deer to expand much. Only on heavier game like boar and red deer these bullets do expand more, especially if heavier bones are hit. For instance, in the roe deer photo I posted above, it is the exit hole that you see! Entrance was exactly opposite.
