Ballistics Question..

I've compared the ballistics between 130 and 150 grain Supreme power point 270 bullets on the Winchester website and the 130 is obviously faster and flater shooting, but it also carries more kinetic energy than the 150..

This may sound dumb but why should I consider the 150 grain? At All! Even for larger game? As I understand it, the two things that cause the most damage is the energy dissipated and the bullet canal created by the mushroomed bullet. I am wondering what the extra 20 grains will buy me at the expense of the velocity, energy and trajectory.. I do feel that velocity is pretty important because really that is what seperates a 150 grain 30/30 from a 150 grain 30/06 or 300 mag..

Thanks in advance for your feedback and opinions.. If you're wondering I am strictly thinking about Barnes X bullets.
