Great hunting bullet. They do expand at the nose end of the bullet, but don't 'mushroom', more of a smashed in nose type thing. The flat point makes a big difference compared to the round nose, that seem to 'distort' more than 'expand'. 18 brinell seems a little too hard to get much expansion, a softer bullet would expand more. I would think that the addition of a hollow point on a bullet like this would make it even meaner than it already is.
