Hollow Points increase stopping power but lower killing power....
Hollow point injuries are shallower which cause them to have a harder time killing the target. What causes the damage of a firearm is not the projectile but the shockwave and the hollow point remove most of the shockwave in favor of direct impact.
Hunting rounds are not hollow points, they are are designed for mass retention and transfer of energy on animals. The bullets best suited to hunting large big game are Impact Extruded and Homogeneous bullets. Due to their tough construction, these types of bullets expand consistently and penetrate deeply.
Other Hunting rounds are fragmentary rounds, bullets that "explode" inside the body at impact.
