They might be made for the military (the bullet although open tip is not designed to mushroom so "legal") and also sold to civilians who want to be very civil at the range -- maybe also sipping tea from a cup and saucer at the shooting bench while the barrel cools in between.
Someone somewhere will do a water jug experiment before and after annealing the tip, but I doubt it will do quite as well as HP soft lead boolits.
