Bingo.
The truncated cone works similar to a semi-wadcutter in that the flat meplat leads to greater energy dump and kinetic energy transfer into the target medium. Stopping power is increased dramatically over standard round nosed ball, which slips and slides through tissue, leading to little wounding.
Not only is that a good quality brand of ammo, it's a great fightsman's load especially when you're wanting more penetration and would turn any 9mm into a serviceable woods gun for defense against smaller woodland four-legged threats, not to mention any goblins hellbent on doing you harm.
In a word, EXCELLENT choice!!
