Preminum bullets really come into there own when trying to drive a bullet through heavy bone such as the shoulder. Heck you can kill elk with a .22 hornet if you hit them in the lungs, but try driving that same bulletthrough the shoulder on a elk coming at you and your looking at a flesh wound. Im a shoulder shooter, prefer not to have to chase an animal and have it fall into someone elses hands, and a big fan of Barnes XLCs and TSXs.
